Instant Centering and Quick Changeover5C, 16C and 3JCollet-Style Expanding Collet Systems

Collet-Style Expanding Collet Systems mount directlyinto the collet angle of the spindle. It is a solid, one-piecebody and arbor combination with a minimum of partsrequired to expand the collet. The expanding arborinstantly locates on center, unlike other designs.

ChangeoverChangeover from one collet size to another within rangeof the arbor size can be done in one minute. Changing toanother arbor size takes only three to five minutes. Nowthat’s Quick.

A2-5, A2-6, A2-8 and 16C, 20C, 25CExpanding Collet SystemsThese Expanding Collet Systems mount directly onto thespindle of the machine. There is no centering adjustmentrequired.

Hardinge® precision manufacturing processes guaranteethe Total Indicator Reading (TIR) of the arbor will bewithin .0002" (.00508mm).

With the Expanding Collet mounted on the arbor, theTIR of the collet and the arbor will not exceed .0005"(.0127mm).

ChangeoverChangeover from one arbor size to another for thespindle-mounted Expanding Collet is approximately fiveto seven minutes. That’s Quick too.

Lowest Possible CostThere are no costly adapters needed to mount the arboronto the spindle. The spindle adapter and arbor are builtinto one inexpensive unit — the lowest-priced unit in theindustry!

Spindle mounts other than A2 series are available.

Wide Gripping Range of Expanding Collets

The Sure-Grip® Center Arbor forGrinding and TurningThe Sure-Grip Arbor Assembly isdesigned to be used on grinders andlathes. The arbor can be held betweencenters, or chucked on one end andsupported by a center on the other end.This expanding arbor assembly style ismanually adjusted.

Locating ShoulderThe arbors have a precision locatingshoulder and diameter so you canfabricate custom workpiece stops.

Maximize Your ProductivityUse two arbors. While one part isrunning, load the next part on thesecond arbor. Then you can load an-other arbor into the spindle when thefirst part is done. This is a big timesaver when chucking one end of thearbor in a collet.

Collet and Arbor Size Ranges

Expanding collets are available in 1⁄64"increments and a full range of metric sizes.The range of each collet is +.015" to -.001"(+.38 to -.025mm) from its specified size.For example, a 1.000" (25.40mm)expanding collet will hold work with a boremeasuring .999" (25.37mm) to 1.015"(25.78mm), eliminating the need fordecimal sizes.

Note: See pages 26-27 for more details

The Hardinge® Sure-Grip® Expanding Collet is adouble-angle design. This design assures true parallelgripping with maximum torque. Generally, specialrestrictors are not needed when gripping a workpiecethat is shorter than the collet’s bearing diameter.

Parallel Gripping

Workpiece

The #100-style expanding collet will handle a rangefrom 1⁄8" to 1⁄2" (3.175 to 12.70mm) and is machinedto size by the customer. It is a unique design with amaster expander as part of the arbor assembly. Thisexpanding collet comes in two styles: #100S with a.300" (7.60mm) long pilot, and #100L with a .718"(18.20mm) long pilot. The recommended grippinglength is a 1:1 ratio with the bore. Example: A 1⁄8"(3.175mm) bore equals a gripping length of1⁄8" (3.175mm).

The Hardinge design requires only a standard hexwrench to remove the collets — no special wrenchesor special tools are needed.

Collet #100S Requires No Work Stops

A major concern with many expanding collets isover-expansion to a point where it is permanentlydistorted or breaks. The Sure-Grip Expanding ColletSystem is designed with a built-in safety feature—thedraw plug bottoms out on the face of the arbor,eliminating over-expansion.

The Sure-Grip® Expanding Collet System assures exact workpiece lengths by locating the part against the faceof the arbor or against the machineable work stop. The collet draws the workpiece firmly against the stop,producing an extremely stable part. The results are heavier cuts, better surface finishes, and closer tolerances.Long parts can be easily machined due to this added stability.

The Sure-Grip Expanding Collet System can be used on anyHardinge spindle as well as all other machines with A2-5,A2-6 and A2-8 spindles. When mounted on Hardinge lathes,a Draw Collet is used. When mounted on ANSI and ISOA2 series spindles, a Draw Bar Adapter is used. The adapter ismachined by the customer to fit the particular spindle’s drawtube/bar. If the customer does not have the ability tomachine the adapter, Hardinge will machine it with quickdelivery and at a nominal cost.

16C Collet-StyleWork Stop System

Draw Bar Adapters

Hardinge® is the expert when it comes to exact part length control.We patented the first Dead-Length 5C and 16C Collets used forhigh-production manufacturing.

The Sure-Grip® Expanding Collet has true part length control builtinto its design. The workpiece locates against the face of the arboror the face of the work stop to ensure no longitudinal endmovement.

All expanding collets (except Model #100) take a machineablework stop that bolts directly to the expanding collet arbor orthe machine’s spindle, ensuring no end movement of theworkpiece. The #400 and #500 5C-style work stops are boltedto an optional threaded or taper-nose spindle mount.

The work stop is machined by the customer to thelocation requirements of the workpiece.

?Sure-Grip® Expanding SystemFrequently Asked Questions

• I plan on taking 1⁄8" off a part while holding on a small bore. Can I use the Model #100?

No. The #100 collet is for light machining operations such as taking a few thousandths off the face or ODof a workpiece. We recommend that you use the Model "S" Precision-Style Expanding Collet for heavierstock removal on parts with bores less than 1⁄2" (12.70mm) in size.

• Can I machine a workpiece without using a work stop?Yes & No. The collet draws back as it grips the bore of the workpiece. Any variation in the gripping diam-eter will cause the part to pull back farther or less than the setup piece. If you are only machining the OD ofthe part, then a work stop is not necessary. Unfortunately, 99% of the time this is not the case. Usually youwill be machining a face or shoulder which has a length dimension that has to be held to a locating surface.This requires a work stop.

• Do I have to buy a different collet for each different bore size?No. The collets will handle a variation in size of -.001" to +.015" (-.025mm to +.381mm). If you have a13⁄4" (6.35mm) collet, it can grip workpieces that have bores from 1.749" to 1.765" (6.10mm to 6.96mm) indiameter.

• Will I damage the expansion collet if I close the collet without a part on it?No. The Sure-Grip System is designed to eliminate this problem. The draw bar will contact the face of thearbor before the collet can be overexpanded.

• Can I buy Emergency Expanding Collets?No. Because the collets come in 1⁄64" (.396mm) sizes and each collet can handle a variation of -.001" to+.015" (-.025mm to +.381mm), there is no need for emergency collets.

• Can I grip internally on a hex-shaped part?Yes. Hex and square collets are available.

• Can I damage my Sure-Grip System if I use too much draw bar force?Yes. The maximum draw bar forces are listed below. If you exceed these forces, damage to the arborassembly may result.
