Precision Design = Life = Value

Unlike other manufacturers, Riten Industries concentrates solely on the science of rotationalworkholding. We are committed to serving our customers with the ultimate in centering tech-nology, and direct all our energies to being the best there is. Thats why our motto isSolutions, not excuses.

With workpiece capabilities from 4 ounces to more than 400,000 pounds, an industry-leading.00008 TIR, and the worlds largest selection of standard and custom models, Riten offersthe widest range of workholding options to satisfy todays global manufacturing requirements.

The Riten threaded seal

adapter/retainer allows easybearing access and is lapped

to be parallel to the bearingface. This guarantees that the

seal adapter makes complete

contact with the face of thebearing for consistent

accuracy and rigidity.

Perpendicularity is paramount in the

manufacture of a precision live center.With the latest in CNC grinding technol-

ogy, each bearing shoulder is held towithin .0001 TIR perpendicular to the

centerline of the taper shank, conform-ing to strict international DIN standards.

This precision is crucial for obtaining

maximum rigidity and service life.

Ritens gageline cross

section, together with ourrobust spindle construction,

is designed to produce excep-tional resistance to deflection.

Some manufacturers claimthat their stubbed spindledesign is superior. The truth

is its simply less expensive to

manufacture. The Riten fulllength spindle design is

supported by multiple bear-ings which spread the load

over the full length of thetaper. Riten bearing bores are

ground concentric and coaxial

to the taper in one operationto .0001 TIR. This combina-

tion assures maximum bear-

ing life and accuracy. Throughprecisely calculated fulcrum

positioning, the full lengthspindle maintains maximum

rigidity, dampens vibration,and will flex rather than break

when subject to severe

moment loads. This uniquedesign is especially important

when supporting heavierworkpieces.

Super Accurate Live Centers

Standard Point


n Ideal for precision grinding

n Compact design

n Extended points available

n Five pounds of thrust to seat bearings


The ultimate live center for precision grinding is provided by Riten's unique design. Medium-duty live centers

are required where the weight of the workpiece is several hundred pounds. These centers are built with

larger bearings to provide the support and strength required to handle heavier workpieces.

chuck is part number 23105-10-4JI. Other chuck sizes and taper shanks

available on request.

Linear Compensating Live Center

Four interchangeable springs provide light, medium, heavy duty and

extra heavy duty axial deflection pressures to compensate for thermal

expansion and varying workpiece dimensions.

Reduced center inventory and significant reductions in set-up time.

Available in tapered and straight shanks, as well as a self-contained

model (shown) that can be chucked for sub-spiindle applications.

Lockable spindle quickly transforms the unit into a carbide tipped

to meet or exceed the manufacturers original speci-

fications, and carry a one-year factory warranty.

Repair and rebuilding

Rebuilt headstock of a large Russian lathe. The

lathe was used to turn rough forged 30 ft. rolls

weighing approximately 20,000 lbs. The rotating

spindle was completely refurbished: bearing boresand shoulders were plated and ground; the ID taper

and mounting face were ground and held concentric

to the bearings within .0002 TIR. The spindle was

reassembled with new bearings and seals and

returned to the customer for installation.

Reground tailstock spindle from a Mazak lathe

with a damaged 6 Morse taper ID. The bearing

bores were in good condition, so the shaft was

steady rested and the Morse taper ID was ground

concentric to the bearings within .0002 TIR. The

spindle was returned to the customer for assembly

into the lathe.

Remanufactured tailstock spindle from a

Cincinnati step grinder. Riten ground, plated and

ground the bearing diameters and shoulders. We

steady rested the spindle and ground the 14 Jarno

taper ID concentric to the bearings within .0002

TIR. The spindle was returned to the customer for

reassembly.

Upgrades and redesigns

Lathe tailstock for rebuild.

The ID was line bored and honed

to restore roundness and size. A

new quill was designed and man-

ufactured. A new bearing assem-

bly was selected to increase

bearing capacity and rigidity. It

used readily available bearings in

the event of future maintenance. A new spindle was

manufactured with a 5 Morse taper ID replacing theproprietary taper found in the old unit. The 5 Morse

taper was selected since it provided commonality

with the customers existing tooling and had the

advantage of being readily available. The tailstock

was completely reassembled and painted prior to

shipment to the customer.

Live quill design and manufacture. Our customer

needed to increase the capacity of a large roll

grinder, but the 7 Morse taper live centers used in

the tailstock would not support any heavier loads.

Riten designed and manufactured anew 9 diameter by 36 long

live quill to replace the

existing dead quill. The

new unit was rated for a

maximum work piece weight

of 40,000 pounds. The spindle featured a replace-

able point option to allow the customer to center

60, 70, and 90 center holes. The tailstock was

honed to size and assembled on site with the new

quill by our field service personnel.

Case study

Hannon Electric Company, which specializes in the

repair and rebuilding of electric motors up through

60,000 HP, had a massive Craven lathe with a 130"

swing and 29 ft. between

centers, which was pur-

chased used. Hannon

was beginning to quote

on new business with

motor shafts weighing up

to 180,000 lbs. The latheneeded exceptional rigidity to meet the required

accuracy of .005" TIR for size, roundness and taper.

It was soon apparent that the tailstock was under-

sized, and was simply being overpowered when

loads began to exceed 70,000 lbs., resulting in dam-

age to the live center. Riten engineers were called in

for a complete functional evaluation of the lathe.

The premature center failures were traced to the

lack of rigidity in the tailstock, which was deflecting

significantly under theheavier loads. Riten pro-

posed a complete

redesign, converting the

dead tailstock to a higher

capacity live tailstock and

quill assembly.

Riten designed and manu-

factured a 16" diameter

live quill rated for a maxi-

mum work piece weight of 200,000 lbs. During the

manufacturing process, Riten provided engineeringoversight, coordinating the efforts of the design firm

and the fabricator responsible for the tailstock. Riten

then installed the quill in the completed tailstock,

and supervised the installation of the entire assembly.

After thorough testing, the lathe was returned to ser-

vice. Final part sizes are now within .002", well

under the required maximum tolerance of .005".

Ever increasing demands on the manufacturer to improve

productivity and quality have led to the need for faster

machining techniques. Face drivers, coupled with modern

high performance equipment, maximize productivity and

increase product quality at minimal expense.

With a Riten Face Driver, the entire work piece is exposed for

machining. Since a face driver locates on the end face of the

shaft, it is possible to machine the entire length of the work

piece in one operation. The single axis reference point estab-

lished by the center point of the face driver allows for a highdegree of accuracy. In comparison, traditional machining

requires multiple operations as the part is reversed to turn

both ends. Accuracy and productivity suffer as the part is

repeatedly chucked. By eliminating operations and setups

the use of a face driver reduces costs, increases productivity

and produces a part with a higher degree of accuracy.

If you are new to face driving or need assis-

tance in selecting a face driver, call Riten at1-800-338-0027 and ask to speak to a face

driver technical specialist. Alternatively, fill

out the Information Request form on page

43 and fax to Riten at 800-338-0717 or email

to [email protected]. A product specialist

will contact you with a recommendation.

The mechanical design has several advantages in compari-

son to the older hydraulic design. It is a true quick changesystem, allowing the interchangeability of drive pins and cen-

ter points with-out disassem-

bling the facedriver.Changing out a

set of drive pinsand a center

point can beaccomplished in less than a minute. During operation the

center point in the mechanical design locks in place providingsuperior rigidity and a higher degree of accuracy in compari-son to the hydraulic design. Depending on the mounting,

concentricity ranges from .0004 -.0008 inches TIR.

Although the hydraulic design requires minor disassembly,

changing out a set of drive pins and a center point can be

accomplished in five to ten minutes. It performs best inroughing applications where part accuracy is not as critical.

The hydraulicdesign compen-

sates for a high-er degree of

inaccuracy inthe part face incomparison to

the mechanical design. Depending on the mounting, concen-tricity ranges from .0015 -.0025 inches TIR.

Both designs are offered in a variety of sizes. This widerange of models offers a high degree of versatility for large

parts, such as large rolls, motor shafts and crankshafts; forsmall parts, such as valve stems, ball studs and automatic

transmission shafts; for rough castings and forgings, such asautomotive gears. Face drivers are used in many betweencenter operations, such as hobbing, milling, shaping, gear

cutting, spline milling, facing and turning.

In addition to traditional turning, face drivers are becomingincreasing popular in both hard turning and grinding applica-tions. Consult the factory in these circumstances since spe-

cial pins and a special face driver may be required.

How Riten Face Drivers improvequality and increase productivity

Complete Turning in One Operation

Riten Face Drivers, used in conjunction with Riten Live orDead Centers (see pages 5, 7 and 8), allow the completeturning or grinding of the entire outside diameter of a

work piece in a single operation. Facing and chamferingof the ends of the part can be accomplished with the

careful selection of the correct face driver, center pointand drive pins.

Unlike a chuck or grinding dog, a face driver grips andturns the part by locating solely on the face of the work

piece. With a chuck or grinding dog, the part must beremoved after the first operation, reversed and rechuckedbefore subsequent operations can be performed. Tradi-

tional machining requires multiple operations and multi-ple setups, increasing costs and cycle times while reduc-

ing part quality.

Aggressive Machining

Properly applied, a Riten Face Driver allows you to takevery aggressive cuts, as much as 1/4 per side. The

chisel-edged drive pins bite deep into the end face of thepart under pressure from the tailstock. The initial cut,

which should be toward the face driver, will help further

seat the pins. Even under the high torque encounteredwith aggressive machining, the drive pins will rotate the

work piece without slippage.

Greater Accuracy and Improved Part Quality

The face drivers center point centers the part, establish-ing the axis of rotation while the drive pins penetrate the

face of the work piece. Clamped between the center inthe tailstock and the face driver in the headstock, the

work piece is ready for machining in a single operation.Continuous machining from end to end in one clamping

improves concentricity of the part.

Repeatability

The accuracy and repeatability of the end face position isassured with face drivers. Under uniform tailstock pres-sures, the drive pins consistently locate and penetratethe work piece within 0.002 from one piece to the next.

Faster Load Times

Load and unload times with a face driver are consistentlyfaster than using drive dogs or chucking. Since the face

driver self-centers the work piece, parts can be loaded inthe machine and clamped in seconds. Chucking takes

considerably longer while the operator ensures that thepart is centered and square in the chuck jaws. Higherthroughput, decreased downtime and increased produc-

tivity can be accomplished with face drivers.

Automatic Part LoadingDue to their self-centering and accurate positioning, facedrivers make it possible to automatically load and unload

the work piece. In some cases, this can be accomplishedwithout stopping the spindle rotation, further increasing

productivity.

Eliminate Facing of the Work piece

Face drivers reduce or eliminate the need to face irregu-lar or out-of-square faces as long as the center hole is

properly drilled. In some cases, even a forged centerhole is sufficient if care is used in selecting the correct

center point. The compensating medium (mechanical orhydraulic) in the face driver assures equal penetration ofthe drive pins, despite variations in the surface or in the

squareness of the face. Even parts with spherical endsor irregular shapes can be clamped securely with face

drivers. These special applications require custom drivepins and center points matched specifically to the

application.


42/68

Selecting a Face DriverIn selecting a face driver several factors should be con-

sidered. As stated earlier, the simplest approach is to fill

out an Information Request form on page 43 and send

it to the factory. The second approach is to fill out the

Information Request form and select the driver yourself

based on material hardness, accuracy required, part

diameter and the required mounting method. You may

find it helpful to fill out the request form as you read the

following example:

Assume you are attempting to turn a 15 long piece of2 diameter bar stock (Dimension S), while maintaining

.0004 TIR. The face driven end finishes at 1.5 in diam-

eter (Dimension F). It has a .380 diameter center hole.

The lathe has an A2-6 spindle nose. Part rotation is

clockwise and the material is under 35 Rc. Harder

materials may require carbide or diamond coated drive

pins. Consult the factory in these circumstances.

Accuracy is dependent on the mounting method and

the design of the driver. Direct spindle mounting with a

flange mount driver is the most accurate, followed bytaper mounts and jaw chucking. Mechanical face drivers

are accurate within .0004 - .0008 TIR depending on

the mounting. Hydraulic face drivers are accurate within

.0015 - .0025 TIR depending on the mounting. In this

example, a flange mount mechanical face driver would

be the best choice since you are trying to achieve

.0004 TIR.

Sizing a Face DriverTo size the driver, determine the minimum stock diame-

ter of the work piece on the face-driven end. Take into

account any chamfers. The drive pin driving diameter

must be smaller than this to allow for tool clearance.

Allow a minimum of .080 clearance between the part

diameter and the driving diameter of the face driver. In

selecting the driving diameter, there are two general

rules of thumb to consider: The maximum stock size

should be no more than 2 2.5 times the driving diam-

eter and the maximum part length should not exceed15 times the driving diameter. Continuing with this

example, a 44FM face driver (page 48) with a driving

diameter of 1.02 1.42 would be a good choice. Even

at the smallest driving diameter, the 44FM satisfies

both rules of thumb. Other drivers will work, but the

44FM is neither too big nor too small.

Center points are selected based on center hole size.

Drive pins are selected based on driving diameter, the

direction of rotation and the choice of center point. In

this example, a C4601 center point will accommodate

the .380 diameter center hole. As stated earlier, whenlooking directly at the driver the rotation is clockwise.

P4404 or P4406 drive pins satisfy both the rotation

requirement and the selection of a C4601 center point.

If several drive pins will work, select the pin with the

largest driving diameter.

To finish the example, the correct selection is a 44FM

face driver, a 708038 spindle adapter, a C4601 center

point and six P4406 drive pins.

Face Driver Installationand setup

Direct Spindle Mounting

Both the FM series of mechanical face drivers andthe F series of hydraulic face drivers can be mount-ed directly to the machine spindle nose with anadapter plate. You will need a flange mount face

driver and the appropriate spindle adapter for yourmachine. Remove the chuck and any adapter platesexposing the machine spindle. Inspect the mounting

taper in addition to the spindle face for burrs, dents,or any irregularities that may affect the proper seat-ing of the new adapter plate. With the adapter, youwill have received fasteners for the face driver,

adjustment (stirring) screws for the adapter plateand an adjustment ring. The stirring screws shouldalready be installed in the adapter plate. The adjust-ment ring will need to be installed on the back face

of the face driver. Gentle tapping with a rubber mal-let should be sufficient to press the ring on the backof the face driver. Install the adapter plate on the

machine spindle nose using the fasteners that origi-nally held the chuck in place.

Once the adapter plate is tightened securely you are

ready to mount the face driver to the spindle

adapter. We recommend removing the center pointfrom the driver since this ID is your primary indicat-ing datum. The fasteners which secure the face

driver to the adapter plate should be snug but nottight since you will be indicating the bore to bring thedriver on center. Make sure the (4) stirring screws in

the adapter are backed off so the driver can beindicated freely. By using the adjusting screws andindicating on the ID, you can bring the face driver on

centerline with the machine spindle. Indicate the dri-ver as close to zero as possible. Tighten the fasten-

ers snugly and check the run out again to make surethat nothing moved off center. Direct mounting isthe most accurate way to mount the driver tominimize part run out.

Chuck Mounting

Flange mount, chuck mount and Morse Taper mountface drivers can all be jaw chucked. This is an

excellent method of utilizing your face driver whenremoving the chuck is not desirable. Although

flange mount drivers are intended to be directmounted, chucking on the flange is an acceptable

practice. It is possible to jaw chuck a Morse Tapermount by inserting the driver in a straight shankadapter sleeve and chucking on the sleeve. Anotheralternative is to jaw chuck the head of the driver,

although care must to taken to avoid damaging theunit. We recommend machining a positive stop orshoulder in your soft jaws to prevent tailstock pres-

sure and cutting forces from pushing the face driverback in the jaws.

Chuck mount face drivers have a six degree reverse

angle machined on the OD of the flange. You shouldmachine your soft jaws to this angle to ensure theface driver is securely locked in position. Once theface driver is securely held in the jaw chuck you

should remove the center point and check the runout. Any eccentricity in the mounting will be reflect-ed in the part.
