KMT Precision Grinding has, today, subsidiaries all over the world. The branches in Boston, Leonberg, Lidköping, Bromma, Gurgaon and Beijing cover all time zones and provide a 24 hours support.

KMT’s subsidiaries in the US, China and Germany are working with sales and aftermarket. The production sites for new machines, rebuilds and repair work are located in Sweden; rebuilds are also performed in Gurgaon, India.

KMT Precision Grinding, today’s world leader in the field of precision grinding machines, is one of the oldest machine manufacturers in Sweden. The company is a merger of UVA International AB and KMT Lidköping, which were founded in 1928 and

1875 respectively as Nomy AB as well as Lidköpings Mekaniska Verkstad AB.

Lidköping started off with the production of exterior lighting, park benches, ploughs and other agricultural products. The engine construction started in 1902 and in 1908, we became one of the first suppliers of SKF, which was established in 1907. UVA began production of hydrody-namic bearings as well as gearboxes for among other things railways. n

Some important dates in KMT’s history:


Grinding determines precision and

thus friction

Photo: BMW

Sverige


The accuracy during grinding of raceways is the most important parameter to obtain a minimum of friction and thereby a long lifecycle and reduced energy consumption. If the friction of all the world’s bearings could be reduced by ten per cent, energy consumption would decrease by what a country the size of Brazil consumes during a year.

The KMT LIDKÖPING brand offers grinders that produce the required surface and shape. The wheels on cars and trains, turbines in all kinds of power stations, the compressor in your fridge - they all contain components that need to rotate with a minimum of friction, year after year, and often under heavy external pressure. The principle is a simple one: less friction, less energy. >>>

>>> The bearings play a considerable role at each rotation in order to reduce friction and guarantee a stable rotation. The requirements regarding the production process are respectively high, not least due to the final shape of the bearings and the finish during grinding and polish.

Adjusts to the customerKMT Precision Grinding has been grinding components for the bearing industry during the last century and during this time KMT has continously made developments of its technology to adapt to different customer applica-tions. Today, wind power is a growing industry and an area KMT is focusing on.

– We follow our customers development in new markets, says Thomas Karlsson, CEO of KMT. When our customer was expanding in the area of wind power stations, new bearing types were needed. We were there and developed new machines covering their needs.

VTG4000 Bearings are found in different locations in a wind power station turbine, such

as e.g. on the fitting of the rotor blade, the turbine axe and the gear box. The better that bearing performs its job, the smoother is the turbine rotation and the lower the energy loss of the mechanic parts.

The rotating rotor blades are connected to the turbine axes through a bearing showing a diameter of upto

four meters. Bearing rings of that size are grinded by a LIDKÖPING vertical grinding machine type VTG4000 and through which the material gets is shape with the help of the optional combination of grinding and lathe.

But there are also smaller sizes found in a wind power station, e.g. turbine axes and gear boxes.

– We adjust to the development of our customers in their markets, says CEO Thomas Karlsson.

>>> The rings for such bearings can begrinded by LIDKÖPING machines, which enable internal and external grinding at the same time in the LIDKÖPING grinding machine model SUUC600. The machine performs rough and fine grinding simultaneously and can therefore replace upto four machines in a conventional production line.

The outer diameter of the bearing ring can also be grinded in a one pass operation in a Centerless grinding machine. The rings are loaded in one line on a workblade into the machine and are grinded by a shaped tool, the grinding wheel. The rings obtain the right shape just in one operation.

Critical processingThomas Karlsson stresses how critical such process is:

– It is determined during the grinding process how accurate the recess, in which the ball will be placed, has to be. The accuracy determines the friction and, consequently, the accuracy of the power generation.

But well grinded bearings with high precision do not only offer the possibility to reduce the energy consumption, but also to improve the reliability.

– If the rotor blades are positions in the wrong axe at high wind forces, this might lead to severe consequences, says Thomas Karlsson. The enormous power may loosen the blades and, that would be worst case, the complete wind power station may collapse.

The global expansion of wind power has slightly reduced lately, even if China has expanded its wind power capacity by 75% in 2010 according to the report of the World Wind Energy Association.

Sales manager Otto Jernström follows the development of the wind power market with interests and realizes:

– The demand will return and that’s when we are ready and able to cover our customers‘ needs. n

EFFICIENTECONOMICAL

ENVIRONMENT FRIENDLY


– There are many reasons to use hydrostatics, says the Technical Manager at KMT Lidköping, Fredrik Wikström. The have been using the technology for a long time and we have very strong solutions.

One solution contains that the movable disc on which the tool holder has been mounted to, a so-called slide, is placed above a fix disc with a hydrostatic bearing in between. The bearing consists of a thin oil film deter-mining the distance between the individual slides to about 0,025 mm.

– Our construction leads to the fact that the force increases through the oil, says Fredrik Wikström. That means that, regardless of what is installed on the upper slide, the distance between the upper and the lower slide remains always the same. Therefore, the slide moves with a very low friction and, consequently, without any wear-and-tear of the machine’s mechanical parts.

Linear motor for fast actionThe slide’s movements are controlled by a linear motor, which has no movable parts. The combination of the linear motor and the hydrostatics leads

to a solution, which basically shows no wear-and-tear. It is a robust solution when high precision grinding and capacity is required. In addition, the linear motor provides the possibility of fast acceleration and retardation.

This requires that the machine is built stiffly. Resistance to forces is only then guaranteed and provides fast reaction time at movement of the spindle.

– Our machines are designed for short cycle times and high precision, says Fredrik Wikström.

Nomyline grinds small detailsUrban Myrefors is Plant Manager at Bromma, where the Nomyline machines are produced. He presents the measurement equipment controlling the parts for fuel injection in a Diesel engine. Less than one thousandth millimeters – that is the deviation allowed at precision grinded parts.

There are different technical solutions in order to reach such values and which makes the difference between Nomyline and its competitors.

– The direct operated chuck presents one of the characteristics. Earlier there was the belt-driven process, which could

lead to vibrations. But as the motor is located directly on the chuck, the parts can be grinded with higher precision and less maintenance.

Another technical solution, which Urban Myrefors likes to stress, it the so-called “Pivoting Spindle Holder“. A unit corrects the minimum bulge of the grinding tools during the grinding process, by placing the slide into such an angle that the contact with the hole in its full length remains. This guarantees that the holes to be grinded are cylindrical within the fraction of one miron (µ).

Notion for technical innovation is the reason for the unique market position of KMT. n

”We offer a number of upgrade packages, which help the customer to further extend his investment.”Björn Almgren, Manager Aftermarket


KMT‘s machines have a very long technical durability – this fact has been known for a long time. That is, among other things, connected to the hydrostatic slides eliminating a mechanic contact. As the customers’ needs change faster than the sustain-ability of the machines, the aftermar-ket department at KMT offers upgrade packages, which extend the machines’ lifecycle.

Upgrading packagesBjörn Almgren, Manager Aftermarket at KMT Bromma, indicates what the company offers:

– We offer a number of upgrade packages, which help the customer to further extend his investment. For example, the chuck’s belt transmission can be replaced by a direct drive. That improves the grinding result and reduces rejection.

– An upgrade of the Uvatronic control system to the actual version 3 contains the exchange of the software, data, bus, amplifier and engines. The customer gains performance improve-ment and better handling.

– Furthermore, we offer optimization of the processes and machine control software, which lead to shorter cycle times and improved quality.

KMT also offers different trainings for machine operators, process technicians and service staff. The training includes theory and practical work and offers the customers understanding and knowledge, which is necessary to use the machines in the best possible way.

Service and spare parts are, naturally, part of the offer just as the online support, during which the KMT engineers are connected through internet with the machine and create a problem analysis.

To make a long story short: an investment in the upgrade of the control system, pneumatic, hydraulic or mechanics increases the capacity and is quickly worth its money. n

The Aftermarket offer supports the customer and extends the machine’s lifecycle KMT Precision Grinding offers a large number of products and services, which provides the customer with a maximum use of his investments. Training, upgrades and optimization present one part of the services provided.

KMT also offers different trainings for machine operators, process technicians and service staff.


UVA Nomyline big at small

details


In Bromma, outside Stockholm, you can find the master of high precision and small measurements.This is the place, where the grinding machines are developed and which, among other things, produce the very accurate parts controlling fuel injection in diesel engines.

Diesel engines in cars, trucks, busses or any other vehicles, is a very sophisti-cated construction, not least when it comes to fuel injection management. The system is based on data controlled injection parts, which inject upto seven times per rate. The fuel forms different layers in the cylinder it ignites and the fuel explodes step-by-step.

Extreme precisionSuch a sophisticated combustion process requires high precision in every operation mode. The injection quantity must be accurate, in quantity as well as in structure.

In order to reach the correct result, the injector that distributes the fuel in the cylinder crucial. Go for any diesel engine in a bus, truck, car or any other vehicle – the chance is rather high that the inner part of the injector and the needle controlling the injection have been grinded by machines produced by KMT. The requirements are very high and the tolerances are measured in thousandth millimeters.

The trademark of these machines is UVA Nomyline, a serie of modular built products, which were launched in 2003 and are known as high quality-products.

>>> – We wanted to develop a Nomyline offering the customer a chuck, which can be indexed, says Per-Erik Pettersson, sales representativeand responsible for the construction ofthe UVAi index.

The solution implies that the machine is able to perform upto four grinding sequences by that the chuck with the detail is indexing to two different positions and these two details are being grinded parallely without a rechucking. For example, a nozzle for diesel can be grinded in one pass, including grinding of holes, lifts and a final face grinding.

That solution was available in the older machine types UVA 88, which were sold to e.g. China and India; but these markets have expressed interest in indexed solutions for Nomyline. Now, here it is. We close co-operation– One of the reasons for our success isour way of how we co-operate with our customers, says Urban Myrefors,Plant Manager. We do not have a traditional supplier-customerrelationship. We cooperate closely, KMT staff have a high presence

at the customer, which leads to continuous communicationand troubleshooting.

Cooperation with BoschAn example on such cooperation isfound in Bromma. A machine typeUVA U88 has been rebuilt to the newstandard. The project leader of Bosch, Torsten Vogel, is visiting Bromma in order to perform several tests required for the final approval. The machine will then be shipped to Nashik, India, to the plant of Bosch. As soon as the machine has arrived in India, Torsten Vogel will be on-site and perform the final approval tests.

– Our cooperation is very good, says

Torsten Vogel. There would have been other manufacturers to do the rebuild of our machines, but it seemed just natural to contact KMT, who is the original manufacturer of the machine.KMT has all the knowledge and competences we prefer. Our communi-cation is very open and good. When itall comes together, it’s a matter of thepeople cooperating. n


At GMN, clocks aren’t ticking faster than elsewhere in the world. Considering the fact however, that we develop high frequency spindles reaching highest rpm per second, it might be assumed that our seconds last longer than usual. By now, we are developing materials and technologies that enable even higher frequencies. And maybe one day, we can even steer the rotating speed of the sweep hand.

SlipNaxos har en 100-årig historia med 185 anställda och en omsättning på 320 mkr år 2010.Vår verksamhet består av utveckling, produktion och försäljning av slip-skivor till industrin över hela världen.Företaget ingår i den schweiziska koncernen Winterthur Technology Group som ägs av 3M med över 7500 personer inom Forskning och Utveckling och runt 80 000 anställda. Största delen av vår produktion består av kundanpassade slipskivor som är utvecklade för en specifik slipoperation eller maskin. Med det stora företagets resurser och det lilla företagets flexibilitet vill vi ge våra kunder bästa möjliga service och lägsta möjliga totalkostnad.

SlipNaxos shows 100 years of company history with 185 employees and a turnover of 320 MSEK in 2010.

Our activity consists in development, production and sales of grinding wheelsto worldwide industries.

The company is part of the Swiss group Winterthur Technology Group, which is owned by 3M with more than 7500 employees within Research and Development anda total of approx. 80.000 employees.

The largest part of our production consists of custom-made grinding wheels, which have been developed to serve a specific grinding operation or machine. The company’s large resources and flexibility enables us to provide our customers with the best possible service and the lowest possible total costs.

The Mechanic Workshop Lidköping delivered already in 1922 their first grinding machine build according to the Centerless principle, which presented one of the first ones of that type in Sweden.

Until to today, KMT has delivered between 7000 and 8000 machines of that type. Machines, which stand for long lasting, smooth operation. Otto Jerström says:

– Lately we have experienced that old customers come back to us after trying other machine suppliers. Our competitors definitely show the same initial values as we do.

But machines made by KMT keep that characteristic for years and years.

Hardly any cleaning after 30 years– We recently got a grinding machine, which was used to grind bars in a steel mill, under heavy conditions for the past 30 years. The machine had to be cleaned, the mechanical parts, though, worked without any problems!

That is one of the reasons, why machines made by KMT are so attractive to the market – regardless whether new or secondhand ones.

The basic construction of the machine types CL630 and CL660 is

sophisticated as well as reliable. Just as the other KMT products, for which solutions are applied based on hydrostatics minimizing friction and, consequently, eliminating wear-and-tear of the respective parts.

The customer mainly use the machines to grind different components for the car industry. A 4-cylinder car engine presents approx. 120 movable parts and more than half of those parts have been grinded according to the Centerless principle.

The construction of the Centerless machines is aligned to grind different types of axes. This might include grinding of bearing position of a camshaft for power steering, universal joints, or piston pins.

If you drive a Volvo, Saab, Volks-wagen, Ford, BMW or Mercedes – just to mention some of the brands – you will find components, which were grinded by KMT machines, in the engine, as the sub-suppliers mostly use established KMT machines.

Extreme high performance machinesCenterless Centerless machines are extreme high performance machines. The axes, pipes as well as the rings of the ball bearings are grinded, which

leads to a very high throughput speed of several meters per minute. One single CL machine is able to supply single parts up to six internal grinding machines.

– Our production development is subject to adjustment of the techno ogy, processes and software (PLC/NC). Today, we often have “fly to wire” machine types, the control becomes more and more intelligent, says Otto Jernström. We do our best to improve our products each year. In 1999, we shipped two machines to Volkswagen Argentina and can now ship another two ones. The customer has developedhis own system and process through out the past years and we adjust the new delivery to the customer’s needs. The machine is not only a machine, but is part of the system, e.g. throughtoolings, peripherals, feeding unit and measurement equipment.

We are not only talking cars. Bearing rings and rollers for a large number of different bearing types, piston for hydraulic cylinders withextremly high demands on roundness and diameter toolerances, steel bars and axes for electric motors. Diameters from 1 up to 275 mm – grinded with KMT Centerless machines. n

KMT’s Centerless machines stand for high productivity – year after year – Continuous improvement of our Centerless machines means ninety years of experience in the machines, says Otto Jernström, sales manager Machines, with pride.

Jörgen Möller is Plant Manager at KMT Lidköping. He describes the intense product development of the past years as follows:

– Until ten years ago, our machines were able to grind parts in sizes of upto 150 mm. Rings for ball and roller bearings are often details by which the needs of our customers have changed and due to the fact that bearings are used in new products.

– Therefore, the development made huge steps and new machines have been developed during the past years. Those machines are able to grind round parts upto a diameter of four millimeters.

That means that KMT’s machine rings for very large ball bearings, e.g. used in wind power stations, trucks and trains, can be grinded. Jörgen thinks that the wind power industry will strongly grow and that China will modernize its railway system – the need of machines producing large bearings will increase.

Worldwide customersKMT Lidköping has customers all over the world and mainly in Germany, France, Sweden, Italy, Spain, Brasil, Argentina, Mexico, USA, China and India. The sales department has been focusing on China and India for the past years. KMT Lidköping constructs and installs its machines in Lidköping.

– This means that our field of activity is deep as well as wide, says Jörgen. Our staff is often involved in the whole project chain, starting with tender preparation followed by the delivery and ending at installation on-site.

Rejuvenation of the staffKMT Lidköping needs well trained staff being skilled in machine and electro-technology, meaning within the construction as well as engineering. 95% of the company’s production is being exported and, therefore, language skills are important as well as feeling comfortable within an international environment.

– We will have to rejuvenate our staff within the following years, as many of our employees are retiring, states Jörgen Möller.

– Our field of activity is motivating as one is involved in numerous project stages and customer contacts. That creates a nice working atmosphere and high engagement within the company.

Unique competenceThe machines are custom-made as configuration may vary. KMT does not have any product lines, all work

independently and in their own responsibility.

KMT experienced, just as the whole industry, many tuff years but Jörgen Möller is optimistic in regard to the future.

– Our company shows a long history of competent and proud employees, who are willing to work. Originally, we were technical-oriented, but we are within a sound conversion phase towards a business oriented company with a unique technological expertise. n

KMT Lidköping focuses on the future

KMT Precision Grinding has been part of the Lidköpingindustry through name changes, economic fluctuationsand technical development.

Jörgen Möller looks optimistic into the future.


Priyank and his staff extend the lifetime of KMT machines

Project manager Anders Karlsson says:– It all started in 2006 as a main-

tenance program for one of our largest customer, who has a considerable activity on the Asian market. But all of our customers can profit from our rebuilding services.

– A rebuild may be done in two ways, says Anders Karlsson. We have a “light” version, which is rebuilt on-site at the customer and which consists of replacement of the electrical control system with the electrical cabinet, push-buttons and wiring. The machines are functioning, most of the times, well in a mechanical parts, thanks to the hydrostatic technology, which eliminates friction at some parts. The electrical components do have a shorter durability, not least due to it being difficult to find spare parts for compo-nents being older than ten years.

– Another alternative is the so-called ”full rebuild”, which includes demount-ing or repair work of and on mechanic parts, re-painting of the machine and giving it an impression of looking new. A full rebuild is performed on-site KMT.

All machines located in Asia, are also rebuilt by KMT staff in India. The machines from other parts of the world are rebuilt in Lidköping, the responsi-bility, though, is always at India.

In India since 2006KMT started its activity in India in 2006 and was planning 25 rebuilds per year.

After some start up difficulties following the establishment, there are now 30-40 rebuilds per year and inquiries are even exceeding that number. In order to meet with the increasing number of inquiries, the company relocated at the beginning of

2011 to Gurgaon. Priyank Garg is the General Manager KMT Production Machinery India.

– Fifteen employees are working here, says Priyank Garg on the phone.It is a young team and the average age is 25–30 years. We have been moving to new locations lately and have now an area of approx. 1200 m2 available. Our equipment is complete and consisting of compressors, cooling system, hydraulics and traverses. We do have our own generator, which is needed in case of power failure.

The machines are running on 100 kilowatt, which the net is unable to produce.

The first international project was a light rebuild at a customer in Bulgaria in May 2011 and during which Priyank was personally present prior tobecome the company’s manager. In the mean -

No one knows the durability of a machine made by KMT Precision Grinding. The KMT machines produced under the brand names LIDKÖPING and UVA are in some parts indestructible. But even such machines become older and that is when KMT can offer a rebuild and essentially extend the durability of the machine.

A large part of those measures were re-located to KMT’s plant in Gurgaon, India, three miles south-west of New Delhi.

time, the plant has performed a complete rebuild of a machine for a customer in China and an order has been received for another three rebuilds.

Several foreign projectsThe number of foreign project is increasing and orders are expected from Malaysia and Brasil. Many

employees have never been abroad before and Priyank accepts the positive challenge.

– Our competence is high and we are continuously building on that fact, says Priyank Garg. One part of our staff is trained in Lidköping, others get an on-the-job-training here in Gurgaon and additional training is performed through Swedish technicians visiting.

We are increasing the number of our staff and assume to have 20 employ-ees by the end of 2011.

Anders Karlsson summarizes:– To be close to our customers and

offer cost-effective service – this was the intention when starting the activity in India The development shows that it was the right thing to do. n
