My term as President of theIndustrial Diamond Association ofAmerica (IDA) is coming to a close. Iwould like to thank the Boardmembers for their support as well asTerry and Kathy Kane who havecontinued to keep the IDA runningsmoothly.

When I assumed the Presidency I settwo main goals ...

First, I wanted to use of webcastconferencing and teleconferences toreduce the cost of Board meetingsand make all our Board moreaccessible throughout the year. Whenour By-Laws were established it wasover 70 years ago and those wordswritten in that document statedmeetings were to be held in-person.Obviously with cell phones, internetand new digital communications “in-person” has taken on a whole newmeaning.

Our Board members are spreadacross the country. The cost in timeand dollars to travel to attend ameeting is very high. Webinars arereplacing the need to travel to on-siteevents in every industry. In Januarywe held our first Webinar Boardmeeting, and while we encountered afew minor technical difficulties, theparticipation in the meeting wasexcellent. I would hope we expandour Webinar experience to allowmore members to participate in IDAeducation seminars and INTERTECH.

Second, I wanted to build closer tieswith other trade associations whosemembers use diamond tools. Wehave done that by tying in otherAssociations and reaching out toshare mutual goals and objectives.

In April the IDA will be holding ourAnnual Membership Meeting in LongBoat Key, Florida. The UnifiedAbrasives Manufacturers Association(UAMA) will also be holding theirconvention at the same site and weare looking forward to an openexchange of ideas and finding waysto support each other. The IDA hasgood relationships with the CSDAand IGGA as well as several othertrade associations—I would like toexpand these relationships as well.

By working together, we becomestronger and increase our ability toimpact the industries and customerswe serve.

As I look back on the past years Ihave served on the Board I ampleased with our accomplishments.The INTERTECH conferences havehad good reviews from attendees andthe last two education programs werewell attended. As we press forwardour education committee will buildon this success and strive to expandthe course content.

I have enjoyed my experiences on theBoard not only as a Director but as Imoved on to become an Officer andthen as President. I now move toserve my final year on the Board asPast President and look forward tocontinuing working with the newBoard of Directors and helping tobuild on the tremendousaccomplishments we have made overthe past few years. I would also liketo encourage more of our membersto seek office in the IndustrialDiamond Association of America; itis a tremendous privilege and achallenging opportunity.

Sincerely,

Keith Reckling, IDA President 2015Industrial Diamond Association of America

PRESIDENTKeith Reckling

In an effort to make the IDA AnnualMeetings more user friendly inINTERTECH years, the IDA Board ofDirectors with the approval of the General Membership have opted to change from a yearly Annual Meeting to a Biennial Meeting on alternating years with INTERTECH. The first meeting has been planned as a joint meeting with the Unified AbrasivesManufacturers Association (UAMA) and therefore we will share certain meeting and speakerevents that are applicable to both Associations. During this meeting the IDA will also holdseparate, focused business meetings and planning sessions for IDA events. Your attendance

is an investment in the future success of your business and in our industry as a whole!

With the tremendous success of INTERTECH Conferences andour education course, Superabrasive Materials, Principles andApplications, the Board feels it is critical that all Members makean effort to participate since we are now only holding thesemeetings every other year.

The IDA has reached and surpassed our goals over the past fewyears and it is important that we continue this momentum withthe active participation of our membership. Remember, this isthe only time when we can all meet as suppliers, customers,competitors and colleagues to share in marketing goals andaddress issues that affect us all throughout all the industries weserve. Here is your chance to have a say in your Associationsactivities and share in that feeling of accomplishment for asuccessful Association! This Meeting will be held April 11-13,2016 at the Resort at Longboat Key Club in Sarasota, Florida.Secluded on a barrier island in the Gulf of Mexico, theenvironmentally-friendly resort is an official Florida "GreenLodging" and just a short drive from the shopping, museumsand theaters in downtown Sarasota.

Along with breathtaking ocean views, guests enjoy oversizedaccommodations with private balconies, eight diverserestaurants & lounges, premier golf and a full-service beachfrontoffering of water sports and relaxation. This Sarasota resort willset the stage for a successful and memorable Biennial Meetingof the IDA and UAMA!

THERE IS STILL TIME TO MAKE THIS IMPORTANT MEETING, SO DON’T MISS IT!


INDUSTRIAL DIAMOND ASSOCIATIONOF AMERICA (IDA)

Biennial MeetingOVERVIEW

April 11-13, 2016

Longboat Key Club ResortLONGBOAT KEY, FLORIDA

The Industrial Diamond Association of America is Celebrating 70 Years!

INTRODUCTIONAfter more than twenty years of commercialization,CVD (Chemical vapor deposition) of diamond-coatedcarbide tooling is still a novelty in some machiningcircles. Even some of the shops currently using moreestablished diamond tooling (bonded grit, PCD) arenot generally aware of CVD Diamond’s capabilities.And some of the best applications for this new

technology are not traditional diamond applications.Some of the problem can be confusion over just what

CVD diamond is and how it is different from otherdiamond tooling. Some simple definitions will be useful to

distinguish between the different types of diamond toolingbefore going into details of how the CVD diamond coating is applied

to cutting tools and a discussion of a documented application.

BONDED DIAMOND GRIT TOOLSBonded diamond grit tools have probably been around since people first had diamond dust and glue.These are what most people think of when you say “diamond coated tools”. Today’s diamond grit toolsuse sophisticated methods to bond natural and synthetic diamond particles to a large variety of cutting,grinding and polishing tools. These tools are used primarily in the construction and mining trades, but

they are also very popular for edge finishing of carbon fiber composite structures and grinding hardmaterials like ceramics and glasses.

PCD DIAMOND TOOLSMost engineers and machinists also know about PCD (Poly-crystalline diamond) tooling. PCD also starts with finediamond particles but they are then formed into a dense sintered material using cobalt as a binder. These cementedcompacts of diamond and cobalt are cut into shape and brazed into solid carbide tool bodies. One popular manufacturerforms the sintered material directly into a slot in the tool body, allowing them to create a wide variety of helixed tools andlonger lengths of cut. The PCD tool edge is then ground to a finished shape and can be reground for repeated use. PCDtools have been around for over 50 years and are widely used in the aerospace industry for hole drilling in carbon fibercomposites. The automotive industry was the first to accept this technology and uses a large number of PCD tipped insertsfor machining highly abrasive cast aluminum-silicone engine components. The tools produced today still have a limitedvariety of geometries available and a high initial cost but they can be the best option in applications demanding a verysharp edge or high impact resistance.

CVD DIAMOND TOOLSCVD diamond is something completely different. Using this new technology, diamond coatings are actually grown atom byatom onto the surface of the tool. Several technologies are used to produce CVD diamond films commercially, but theprimary method used for coating cutting tools is known as Hot Filament Deposition. Inside the typical coating system, anarray of superheated tungsten wires are used to activate hydrogen and a carbon-containing gas (usually methane). Thisreactive vapor mixture will condense onto the part to be coated, producing the diamond film over the entire surface of thetool. The diamond crystal growth is carefully controlled to produce a high-purity diamond film with a microstructure suitedto the machining application. The coatings are from 4 to 40 microns in thickness depending on tool diameter andapplication. These films are pure diamond with no binder; they are both mechanically and chemically bonded to the toolsurface. The result is the ability to combine the latest in cutting tool geometry with the superior mechanical properties of diamond.

An Introductionto CVD Diamondfor Cutting Tools

Authors - ED FRANCIS, VPand CHRIS ENGDAHL, VP

ADVANTAGES OF DIAMOND TOOLSDiamond has many unique physical properties and some thatmake it an ideal material for cutting tool applications (Figure 1).Of course it is the hardest known material and so is extremelyabrasion resistant. And the extremely high thermal conductivityof diamond removes damaging heat from the cutting edge.Diamond’s low coefficient of friction (similar to Teflon) aids inchip formation and material flow up the flutes of the coatedtools. These thermal and wear properties mean diamond toolscan be run at speeds that would destroy all other coatingmaterials. And when used at normal speeds diamond toolsoperate cooler than other tool materials, reducing damage to heatsensitive work-piece materials.

So what does CVD diamond machine well? Many of the advancedcomposite materials that are gaining in popularity lately areperfectly suited to be machined with CVD diamond tooling.Carbon fiber composites, green ceramics, fiber reinforced plasticand graphite/graphite composites are all materials that rapidlywear out standard tooling, and they are also materials where CVDdiamond has proven its performance. Other suitable materials aregraphite, high silicone aluminum, and metal matrix materials.Diamond is not for everything though; it will not machine any ofthe ferrous materials due to a chemical reaction between the ironin these metals and the carbon atoms making up the diamondfilm. Some positive results have been shown using liquid nitrogento flood the work area to control the cutting temperature whencutting cast iron by General Motors. And no, it is not the answerto all of your titanium problems, though it can machine it, butnot cost effectively. CVD diamond films can be a new solution tomany other difficult to machine materials. The ideal CVDDiamond tooling applications are those where machining thematerial forms powder or small grit. These are situations wherethe primary operation at the cutting edge is basically abrasivewear rather than chip formation. Materials like graphite orfiberglass are perfect examples. The best application is machiningceramics in the green state (unfired), when machining these waxyabrasive materials, the CVD diamond coating will last from 50 to70 times longer than standard carbide.

TOOL MATERIALSelection of the proper tool material is crucial to the success ofthe diamond coating process. The prolonged high temperaturenecessary during the coating process will damage all butcemented tungsten-carbide and ceramic cutting tool materials.And for the optimum coating adhesion, a C-2 grade of tungsten-carbide must be used (6% cobalt binder, grain size above 1micron). Once you obtain the correct material, the tool grindingmust be carefully performed. Any overheating of the tungsten-carbide during grinding operations (burning) will damage thecarbide surface and cause the diamond film to flake off of theburned areas.

SURFACE PREPARATIONCareful preparation of the tungsten-carbide toolsbefore diamond coating is another of the keys toconsistent performance. The parts to be coatedare carefully cleaned and then typically putthrough a two-step chemical preparation. Thefirst step roughens the carbide surface forimproved mechanical adhesion (Figure 2) andthe second step removes cobalt from the surfaceto optimize chemical adhesion. Other methodsinvolve micro-blasting processes to optimize thephysical roughening, interlayer films and re-sintering steps designed to improve chemicaladhesion.

COATING PROCESSNext the parts are loaded into vacuum chamber containinghydrogen and methane gasses at a vacuum of 10 to 100 torr. Aseries of tungsten wires, heated to over 2300 degrees C, are usedto provide the energy necessary to both break-up the gasmolecules and heat the tools to over 750 degrees C (Figure 3).When the proper conditions are achieved, the activated carbonatoms can recombine into a pure diamond film over the entiretool surface.During the initial growth phase the carbon atoms will formdiamond crystallites in the crevasses between the tungsten carbidegrains. Thesecrystallites will grow to form a continuous film thatis both mechanically interlocked with the etched tungsten carbidestructure and chemicallybonded to the tungsten carbide grains.(Figure 4). One of the reasons that the cobalt content is limited isdue to the graphite that initially grows onthe cobalt and providesno adhesion.This coating process is very slow, with typical film growth rates ofonly .5 to 1.5 microns per hour. Since functional coatingthicknesses range from 2 to 40 microns, this can mean very longgrowth cycles of 2 days or longer.Another unique advantage of the CVD diamond coating process isthe ability to grow a wide range of surface structures and optimizethe film for a given application. (See Figures 5-8) When tool edgesharpness is a primary issue, the diamond film can be grown thinand very smooth. If abrasion is the main wear, mechanism andthicker films are needed, growing a faceted surface has beenshown to reduce the cutting forces and increase lifetime.

CARBON FIBER COMPOSITE APPLICATIONDrilling and countersinking in carbon fiber composites are justthe type of abrasive machining operations that are perfect forCVD diamond coatings. The first example is drilling andcountersinking rivet holes in a 7.6mm thick carbon fiberlaminate. The tool used was a combination 6.1mm diameter drill/ 13mm diameter countersink running at 3000 rpm and a feedrate of 280 mm/min. Results of testing conducted in a NIST/ATPfunded program at Boeing Aircraft in Seattle, WA are shown in thegraph. (Figure 9) The coating used here has a faceted surface andcutting edge (Figures 10 & 11) as compared to the ground edge ofthe carbide and PCD tools. This faceting is responsible forreducing the cutting forces that could normally be expected withsuch a thick coating (20 microns).The data (Figure 9) show how abrasive this material is onstandard carbide tooling, typically wearing out a tool in less than200 holes. Due to the sharp grind on the uncoated tool, theinitial thrust is low but rises quickly as the edge wears away. APCD tool can do the job quite well, but still has a shorter life. TheCVD coated tool has the best performance with low thrust, verynice quality holes and minimal backsidedelamination.Although end of life for this test was 50 lbs, theCVD tools were still producing high qualityholes, with very graceful wear. The tools will lastlonger on the shop floor where end of life iscloser to 60 lbs.

RECOMENDED MACHININGCONDITIONSIf your plant is using tungsten-carbide toolingalready, you pretty much know how to use CVDdiamond. It requires the same setup astungstencarbide for optimum performance: rigidtool holding, high quality spindles and solidwork piece fixtures. But remember, the diamond

CONCLUSION Like any new product, CVD diamond tools will need to prove their value on your shop floor beforethey really make sense to you. But CVD diamond has become a mature technology, which has the potential to dramaticallyreduce tooling cost and perhaps solve some problems at the same time. There are now several companies producingdiamond-coated tools for the aerospace industries. Many of the standard tools in use today are available in thesecompany’s catalogs. If you are willing to provide carbide tools ground from a suitable grade of carbide, the major diamondcoaters will usually coat those tools as samples for evaluation in your particular application.

cutting edge can survive a much higher temperature and so thetool can be run at a higher speed. The basic advice is to run atyour highest effective spindle speed and then increase your feedrate until you have the same chip load per rotation as you wouldwhen running your carbide tools under full load. The full rangeof cutting speeds and feeds for specific materials are available onthe web sites of all the major CVD diamond tool coaters and toolcompanies.

ECONOMICSAnd so, is it worth it? CVD diamond coated tools are typicallypriced at 4 to 6 times the cost of uncoated tungsten-carbidetooling, but for that price you receive 8x to 15x increase inlifetime. This translates into a net tooling cost reduction of 40%to 80%. Additionally, the increased tolerance control anduninterrupted machining can have a big impact on overallproductivity. And if your spindle is capable of high speeds(+15,000 rpm) you can take full advantage of CVD diamond’sproperties to increase your production rates. If we are comparingto PCD tooling we have seen that the CVD tool will have equal orbetter performance in many applications. The cost of the CVDtool is approximately equal to the regrinding cost of the muchmore expensive PCD tool. A single use tool also has advantagesrelated to the necessary inventory control and breakage lossduring handling and regrinding of the PCD tooling. ●


ELEMENT SIX EXHIBITS INNOVATION WITHDIAMOND PUREOPTICS, HIGH-POWER DIAMOND LASER, ANDLANDMARK QUANTUM MECHANICSElement Six’s most recent developments is its Diamond PureOptics, thefirst all-diamond optic delivering an order of magnitude with higherperformance for high power laser systems. With meta-surfaces etched into diamond, DiamondPureOptics mimics the structure of a moth’s eye which eliminates the need for thin film coatings,enabling more than 10 times increase in damage thresholds for high-power laser applicationsincluding EUV lithography. In other news, Element Six’s diamond was used by researchers at MQPhotonics Research Centre to demonstrate a high-power diamond laser 20 times more powerful thanprevious diamond laser systems at an emission wavelength of 1240 nm. Leveraging Element Six’slow-absorption singlecrystal chemical vapor deposited diamond, the research team developed a laserthat delivered up to 380 Watts of output power, which is the equivalent of approximately 400,000laser pointers and enough power to cut through steel. Delft University of Technology is anotherorganization that leveraged Element Six’s diamond, using it to successfully complete a landmarkexperiment testing quantum mechanics. With Delft, Element Six provided a nanoengineered syntheticCVD diamond to, for the first time, quantum mechanically entangle two defects over a distance of 1.3km—a major leap forward for quantum science.

FIVES SHOWCASED ITS NEW “TWIN TURRET” CRANFIELD PRECISIONMACHINING PLATFORM AT GRINDTEC 2016

The new machine is a radically new concept that coordinates two rotary axesand a short linear axis in a “Twin Turret” design. It uses a uniquecombination of rotary and linear axes to produce relative motion (bothposition and angle) between tool and workpiece over a swept working area.The new machine base is effectively two rotary, highly damped hydrostaticbearings that resist machining forces. The “Twin Turret” design enables asimple non-contacting labyrinth seal, making the machine base almostimmune to distortions. These are usually caused by the heat generated from

constantly changing coolant return path as the grinding wheel carriage moves along the linear axis.The new design responds to the needs of the most demanding applications looking for extremeaccuracy in their grinding processes. For more information visit www.fivesgroup.com

IT WAS THE BEST OF TIMES,IT WAS THE WORST OF TIMES

The first few words of the classic “A Tale ofTwo Cities” written over a century and a halfago still invoke images of a world torn apartin the throes of a violent revolution. Wordshave that effect and it just shows how a well-versed statement can span the decades andstill send a distinguishable message that stirsour imagination.

Writers get a certain thrill from being able toput together just the right words in the rightorder to tell a story, but most importantly, to

tell a true story! In a like manner it is exciting to design an ad and deliver that“certain” message in a few words with an eye-catching image.

When you are trying to sell a product or get your message across don’t you dothe same thing, or at least have your ad agency do this for you? How aboutwhen you give a speech or presentation? Do you make your audience want tosit in those seats and listen to what you have to say? Sure you do!

I get a tremendous kick out of good speeches, advertisements andcommercials. I like the clever and the outrageous that bid for my attention.Advertisements are sometimes recognized as the best written items in amagazine or a newspaper. Why? Because they have to attract your attentionand deliver a message in the shortest time possible. When we leaf through thepages of a magazine what makes us stop and look, bright colors or a cleverimage? You bet ... and if it’s really good we may even peruse the words to seewhat they actually have to say.

Advertising is important and well-done advertising is essential! Why advertise?Maybe it’s to herald a new product or proclaim a leading technologicaladvantage over your competitors, these are both great goals. But advertisinghas a secondary purpose many of us miss and the clever ones seize, it’s to juststick your foot in the door of your audience and say, “We are here for you,take notice”.

There is a reason that companies spend mega-bucks on 15 seconds of airtimeat the Superbowl! Some companies want to announce they are out there, butseriously, most of those wild commercials are for colas, beers and nachos wealready consume! They want to stamp an indelible mark in our subconsciousto remember them when we reach for a cola and a bag of chips!!! A few yearsago the advertising industry reported the leading cola manufacturer hadbacked off its advertising and an “uncola” made a big ad push, the result ...the big guy saw a significant loss in sales!

Advertising does work ... In our industry we stress how education of ourcustomers is critical to see the growth in the use of superabrasives. In the sameway, education of the companies in our industry to get their message out onwho they are and what they do is just as important.

If advertising didn’t work we wouldn’t see all the politicians cramming theairwaves, stuffing the newspapers and posting signs on every street corner and yard!

To paraphrase another memorable line, “It is a far, far better thing you can do,than you have ever done, it is a far, far better message you can send, that youhave ever known”.

The Value of Lab-Grown CVD Diamond in

Industrial Applications

by BRADLEY BAILEY

Scio Diamond

The extraordinary physical properties of diamond make itideal for industrial applications. When businesses need thequality, consistency and hardness of diamond for precisionmanufacturing, such as diamond-tipped bits and blades for

cutting tools, monocrystalline chemical vapor deposition(CVD) lab-grown diamond is the ideal choice. This article willreview the value of diamond over other materials in industrial

applications, and how CVD lab-grown diamond providessubstantial advantages over mined materials.



Diamond Material vs. Other MaterialsCVD diamond is an ideal alternative to other materials, such as carbide orsapphire, that are used in precision cutting, machining and finishing of a variety ofproducts. These softer materials wear much faster, requiring companies topurchase them more frequently and shut down the manufacturing line to changethem more often. Sometimes, minute pieces of the material that have worn awaycan be deposited into the machine and damage it. While the initial price per unitof other materials may be lower, the higher quantities required, repeatedmanufacturing shut-downs and risk for damaging expensive manufacturingequipment make them less cost-effective over time.

Applications for Diamond MaterialThere are many industrial applications where diamond material providesnoteworthy advantages to businesses. In the case of precision cuttingapplications, the longevity and hardness of CVD diamond delivers special value tothe manufacturer.

Cost Comparison: Diamond Material vs. Other MaterialsAn analysis of the cost of using diamond vs. ruby or sapphire for water jet nozzles,and diamond vs. carbide for end mills shows the potential cost savings with CVDdiamond.

Advantages of Lab-Grown Diamond MaterialWith clear cost advantages to using diamond material over other materials,businesses also have a choice in selecting diamond that has been mined ordiamond that was grown in a highly controlled laboratory setting.

Lab-grown diamond is defect free, while it is difficult to find mined diamondmaterial without inclusions or cracks. Defective mined diamond material cannot beused for industrial cutters or water jet nozzles because the defects will cause the

tooling to shatter in machines, requiring extensive shut-down periods andsometimes damaging the equipment. Also, because diamond tools often operateunder high stress or pressure, if a cleavage plane is within the tool, it will mostcertainly fail. These situations are costly in terms of delayed manufacturing andshipping, unanticipated expenses, and potential damage to customer satisfactiondue to late deliveries.

It is also challenging to find mined diamond material with the correct orientationfor a specific application. The orientation of the crystal plane is important becausethe hardness of diamond is different depending on the plane. Diamond behavesdifferently during post-growth processing and actual use depending on whichcrystallographic plane it is cut on. Most companies use the [100] 4-point plane,although some use the [110] 2-point plane.

CVD diamond can be grown with a known orientation repeatedly by using seedstock with a known orientation. With mined diamond, the orientation is not knownuntil it is removed from the ground and tested. This testing can increase the priceof diamond material, so lab-grown diamond can be more cost-effective.

Highly precise control over diamond material is only possible when it is grownrather than mined. The growth process creates a highly repeatable and scalablemanufacturing platform. A diamond-growing company can produce largenumbers of identical products. For industrial use, consistency is essential, but itcan’t be achieved with mined diamond. In addition, lab-grown diamond can becustom manufactured to provide the exact orientation required by a company

Lab-grown material offers cost savings to businesses that must keep tight controlof manufacturing budgets. With lab-grown diamond, companies can get larger orhigher quality material for the same price as mined diamond, or identicalproperties for a lower price. Over time, this cost savings can mean millions tosome manufacturers. ●

GUEST EDITORIALSUPERABRASIVES FACE NEW OECD AND G20 RULES

By: ROBERT FEINSCHREIBER and MARGARET KENT,Attorneys at TransferPricingConsorium.com

Superabrasivebusinesses now mustface the wrath of the

OECD (Organization for Economic Development) and similarresponse from the largest of governmental powers, the G20. Thesetrans-governmental institutions initiated special pricing rulesbeginning January 2016 impacting a broad-based “commodity”business segment. These pricing rules are not neutral - thesecommodity rules favor governments having mining operations intheir territories. These rules enable these governments to capturemore income than before, taxing the difference in values. Resource-rich developing countries initiated these valuation rules becausethey feared the power of large multinational enterprises, treating allsuch businesses with the same brush. 92 countries have signed-onwith the OECD and G20, with more countries to follow.These new OECD and G20 rules enable governments to increasecommodity values in their member jurisdictions. Here is why thisapproach matters to resource-rich countries: Enterprises in that initialjurisdiction will receive more revenue because of these rules. Thegovernments, then, will have more tax revenue. Of course, manysuperabrasives products are not commodities, and these new rulesdon’t affect those superabrasives.These OECD and G20 commodity rules are quite complex. You’llneed an international tax professional to guide you through the mazebefore you face an international tax audit. Superabrasive memberssubject to the new commodity rules should develop a database tocope with potential future tax audits. The OECD and the G20 bringuneven results to the superabrisive industry by challenging somesuperabasive members, but excluding others The IRS initiated thecommodity transfer pricing rules a quarter of a century ago. We are

pleased that the IRS consulted with us in developing those rules.TransferPricingConsortium.com has been successful in forestallingIRS tax abuses for clients in the commodity transfer pricing context.The OECD has 34 members and the G20 has 20 members. Withduplications, we’re talking about 40 countries. The OECD and theG20 are trying to get other countries to join their efforts. The OECD’sGlobal Forum and the G20’s Development Working Groupencompass virtually all countries on earth. Sophisticated membersprovide “knowledge, best practices, and tools” for unsophisticated“commodity-rich countries” in pricing commodity transactions fortransfer pricing purposes. The tax administration can ascertain whatindependent enterprises would have agreed to in comparablecircumstances, taking industry practices into account. Thesecommodity rules give tax administrations an upper hand against themultinational enterprise.Tax administrations can make their pricing determination claimsbased on the best available evidence they can obtain. This evidencemight include the date of shipment, as evidenced by the bill oflanding, contracts, or equivalent documents, depending on themeans of transport. In that situation, the tax administration can applythe price applicable to commodities being transported by referenceto the average quoted price on the shipment date. Be warned: Thetax administration might utilize comparability adjustments based onthe information it has available, but the taxpayer might notnecessarily have the same information available.

DC Torch/Plasma-Arc CVD Reactors for Free Standing Diamond


Typically, CVD grown diamond is created in a vacuum chamber of somekind, with a heat source (typically either by microwave, hot filament, or atorch arrangement). Carbon-rich gases are then introduced into the vacuumchamber and the heat source causes a reaction that causes diamondcrystals to form and bond to one another without a catalyst (which is oftenincorrectly referred to as a “binder”).

CVD diamond sheet is grown flat in the form of a disc and then is lappedand polished to various thicknesses (commonly 500 microns to 2 millimeters)and finishes depending on the application requirements. CVD Free-standingDiamond Sheet shown in Reactor Chamber

The discs are then laser cut into segments that are later brazed to the cuttingtool blank.

The blank can be carbide inserts, steel or carbide cartridges, pockets in afixed pocket tool such as a reamer and other cutting tool forms that utilize flatdiamond as the cutting material.

After brazing, the final form and size of the cutting tool edge can beprecision finished with a CNC laser, or CNC ground with diamond grindingwheels.

Typical applications for CVD diamond coated tools are in highly abrasivenon-metallic materials such as carbon fiber reinforced plastics (CFRP) andother composite materials such as Kevlar or fiberglass; green state ceramicmachining for semiconductor and ballistic armor manufacture; green

CVD DIAMOND CUTTING TOOL APPLICATIONSBy ERIK KOIK, sp3 Cutting Tools

Diamond is created in natureby heat and pressure, aprocess that can beduplicated in a manufacturingenvironment by usinghydraulic presses and a heatsource combined with acatalyst (typically cobalt)which causes the diamondcrystals to bond chemicallyand creates a PolycrystallineDiamond (commonly calledPCD). Diamond can also becreated by the ChemicalVapor Deposition (commonlycalled CVD) process whichuses heat and vacuum togrow diamond crystals eitheras a free standing material oras a coating on varioussubstrates like tungstencarbide, silicon or GalliumArsenide.

carbides used for wear parts or even for cutting tool forms, and forgraphite materials used in industries such as mold making or fuelcell production. CVD Diamond tools made from diamond sheetmaterial are typically used in abrasive, non-ferrous applications suchas silicon aluminums, metal matrix composites and CFRP.

The main advantages of CVD grown diamond are:

● Greater abrasion resistance than conventional PCD because ofgreater density of pure diamond in a given area

● Greater resistance to thermal issues caused by Coefficient ofThermal Expansion (CTE) mismatch between the cobalt and thediamond that occurs during machining processes

● No susceptibility to weakening during the machining processcaused by cobalt leaching out of the material because of reactionto coolants, resin systems and the like

● Best possible heat transfer from the cutting edge as diamond isthe best heat conductor in nature

● Potential for creating a sharper, finer cutting edge because of thehigher diamond density and no possibility of cobalt flaking out ofthe cutting edge

● All of these characteristics contribute to greater tool life; in somecases, up to 5 times the life of conventional PCD

● Additionally, CVD grown diamond can be used as a coating overcomplex tool geometries such as helical end mills, drills, insertsand the like

● This capability allows for more efficient and effective tool designs

The disadvantages of CVD grown diamond are:

● Lower fracture toughness than PCD, so less appropriate for heavyimpact situations or where cutting forces are high or material hasvoids that cause interruptions

● Higher cost per square centimeter to manufacture the raw materialthan conventional PCD

● CVD material is non-conductive electrically (unless doped withBoron or other conductive materials) and so cannot be cut usingElectrical Discharge Machining (EDM); typically, lasers areemployed for cutting and trimming CVD diamond.

● Grinding of CVD diamond for finished form and size is more costlythan grinding conventional PCD because of the higher diamondcontent

● CVD diamond coated tools lack the sharpness of a ground edgebecause the diamond grows first where the substrate has thehighest temperature and this is typically on the cutting edge

The advantages of CVD diamond often outweigh the disadvantagesbecause the characteristics of tools made with CVD diamond haveunique properties that give them significant advantages overconventional PCD.

For example, if the failure mode of a tool is edge/flank wear thatcauses burrs to form on a workpiece; CVD diamond will typically runfar longer than conventional CVD before burr formation starts to takeplace. Tool geometry for certain component/machine/fixtureconfigurations can further extend tool life before burrs become an issue.

Another advantage of CVD diamond when compared to conventionalPCD is in applications where controlling size to extremely tighttolerances is critical. In fine reaming applications where hole sizesare required to be held within a few microns or less, CVD diamond’swear resistance can result in a tool running multiples of tool life vs.conventional PCD before wear causes the hole diameter to runundersize and out of tolerance. An automotive transmission valvebody spool bore is one of the most difficult applications inmanufacturing due to the aluminum composition utilized. CVD

diamond will give 2x the tool life of conventional PCD in someinstances.

Another application where controlling size is the key issue is in thetrimming of carbon fiber (CFRP) composite structures. Tool wear overthe course of machining a long, continuous cutter path in CFRP(such as spars and stringers, door and window opening, etc.) cancause even conventional PCD tools to wear enough in the cut to runout of tolerance before the cut is finished. Simply changing tools isnot an acceptable solution due to the mismatch marks created bychanging tools. The longer life of CVD diamond when used in routingand trimming applications justifies the higher manufacturing cost inmany cases.

Channel milling of graphite with tight tolerances (+/- 25 microns) forwidth, and extreme requirements for perpendicularity of the channelwalls combined with difficult to achieve surface finish requirements istough enough to achieve over small lengths of cut. But when thechannel is part of a fuel cell and the length of cut of the entirechannel is 20 meters or more, CVD diamond is the only possible wayto achieve the requirements with single tool.

CVD diamond is again the cutting edge material of choice inapplications where its characteristics of wear resistance, ability tohold size and finish, and where helical geometry and shape are ofvalue to the end user. ●


Diamond Tipped Step-reamer with CVD tips

In summary, the unique advantages of CVD Diamond: wear resistance, chemical inertness, andflexibility of edge geometry are unavailable with other PCD materials. CVD Diamond willbecome an ever-increasingly used material where requirements for accurate machining of largevolume components from abrasive materials drive product performance. In some cases, CVDDiamond is the only practical economic alternative.
