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.

Riten Repair/Trade-In Program
In response to a numberof customer requests,Riten has developed anin-plant survey programthat helps you gain con-trol of live and dead cen-ter availability and cost.
An authorized Riten rep-resentative, together withthe distributor of yourchoice, conducts a com-plete inventory of all centers at your plant. Theresult is a written report listing all centers found at
your location, their condition, standardization sug-gestions, identification of duplicates, and trade-inopportunities. This information is extremely valuablein making sure the right centers are on hand,streamlining your inventory, and cutting costs.
This program is free to qualified customers. Torequest a center survey, call Riten Customer Serviceat 1-800-338-0027, or log on to www.riten.com.Samples of previous customer surveys can be pro-vided on request.

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.

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.
