3 Sure-Grip Expanding Collet Systems WORKHOLDING for all machine brands Collet-Style Expanding Collet Systems 5C, 16C and 3J Collet-Style Expanding Collet Systems 5C Collet System mount directly into the collet angle of the spindle. It is a solid, one-piece body and arbor combination with a minimum of parts required to expand the collet. The expanding arbor instantly locates on Styles for all machine brands Collet-Style, Spindle- Mount Style and Center rbors. center, unlike other designs. Changeover from one collet size to another within range of the arbor size can be done in one minute. Changing Benefit from reduced changeover time and quick centering. to another arbor size takes three to five minutes. Now that s Quick. 16C Collet System Spindle-Mount Style Expanding Collet Systems 2-5, 2-6, 2-8 and 16C, 20C, 25C These Expanding Collet Systems mount directly onto the spindle of the machine. There is no centering adjustment required. 3J Collet System Hardinge precision manufacturing processes guarantee that the Total Indicator Reading (TIR) of the arbor will be within.0002" (.00508mm). With the expanding collet mounted on the arbor, the TIR of the collet and the arbor will not exceed.0005" (.0127mm). Spindle mounts other than 2 series are available. Changeover from one arbor size to 2-5, 2-6 and 2-8 Collet System No costly adapters to mount the arbor onto the spindle all built into one inexpensive unit for the lowest-priced assembly in the industry! another in this style is approximately five to seven minutes. That s Quick too. 3

4 Center rbors for Precision Machining The Sure-Grip rbor assembly is designed to be used on grinding machines and lathes. The arbor can be held between centers, or chucked on one end and supported by a center on the other end. This expanding arbor assembly style is manually adjusted. The arbors have a precision locating shoulder and diameter so you can fabricate custom workpiece stops. Maximize your productivity by using two arbors. While one part is running, load the next part on the second arbor. Then you can load another arbor into the spindle when the first part is done. This is a big time saver when chucking one end of the arbor in a collet. The gripping range of each collet is +.015" to -.001" (+.38 to -.025mm) from its specified size. Sure-Grip 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 bore measuring.999" (25.37mm) to 1.015" (25.78mm), eliminating the need for decimal sizes.

5 Hardinge Design Expertise WORKHOLDING for all machine brands True Parallel Gripping Workpiece Parallel Gripping The Hardinge Sure-Grip Expanding Collet is a double-angle design. This design assures true parallel gripping of the work-piece with maximum torque. Generally, special restrictors are not needed when gripping a workpiece that is shorter than the collet s bearing diameter. Built-in Safety Feature Interchangeable Collets Small Diameter Capacity The #100-style expanding collet will handle a range from 1 8" to 1 2" (3.175 to 12.70mm) and is machined to size by the customer. It is a unique design with a master expander as part of the arbor assembly. This expanding collet comes in two styles: #100S with a.300" (7.60mm) long pilot, and #100L with a.718" (18.20mm) long pilot. The recommended gripping length is a 1:1 ratio with the bore. For example: a 1 8" (3.175mm) bore equals a gripping length of 1 8" (3.175mm). The Hardinge design requires only a standard hex wrench to remove the collets. No special wrenches or special tools are needed. #100 Collet-Style Expanding ssembly Requires No Work Stops Collet #100S Safety Stop Location Maximum Stroke HRDINGE #100L Collet #100L Collet Draw Plug Safety Stop major concern with many expanding collets is over-expansion to a point where the collet is permanently distorted or it breaks. The Sure-Grip Expanding Collet System is designed with a built-in safety feature the draw plug bottoms out on the face of the arbor, eliminating overexpansion. Interchangeable Collets Different Sure-Grip Expanding Collet Systems use the same collets for the grinding/turning arbor as they do for the spindle-mounted and collet-style expanding collet assemblies. This lets you use one set of collets for both your grinding and turning applications. Specials Sure-Grip Collets can be custom manufactured for special applications for spindles, sub-spindles and mill tables. Pick-off collets are frequently engineered for Swiss and multi-spindle machines. Splined or serrated surfaces can be made for special grips and shapes, while recessed draw plug styles might solve your short gripping problem. 5

6 Exact Part Length Control The Sure-Grip Expanding Collet System assures exact workpiece lengths by locating the part against the face of the arbor or against a 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.

7 Dead-Length Work Stops and Draw Bar dapters WORKHOLDING for all machine brands Hardinge Work Stop bored and faced by customer for part length control of short workpiece 16C Collet-Style Dead-Length Work Stop Hardinge is the expert when it comes to exact part length control. We patented the first Dead-Length 5C and 16C collets used for high-production manufacturing. The Sure-Grip Expanding Collet has true part length control built into its design. The workpiece locates against the face of the arbor or the face of the work stop to ensure no longitudinal end movement. Threaded Spindle Mount 3J Collet-Style Work Stop ll expanding collets, except Model #100, take a machineable work stop that bolts directly to the expanding collet arbor or the machine s spindle, ensuring no end movement of the workpiece. The #400 and #500 5C-Style work stops are bolted to an optional threaded- or taper-nose spindle mount. Draw Bar dapters The Sure-Grip Expanding Collet System can be used on any Hardinge spindle as well as all other machines with 2-5, 2-6 and 2-8 spindles. When mounted on Hardinge lathes, a Draw Collet is used. When mounted on NSI and ISO 2 series spindles, a Draw Bar dapter is used. The adapter is machined by the customer to fit the particular spindle s draw tube/bar. If the customer does not have the ability to machine the adapter, Hardinge will machine it with quick delivery and at a nominal cost.

8 ? Can I or can t I? Check the frequently sked Questions below: Frequently sked Questions: Can I machine a workpiece without using a work stop? Yes & No. The collet draws back as it grips the bore of the workpiece. ny variation in the gripping diameter will cause the part to pull back farther or less than the setup piece. If you are only machining the OD of the part, then a work stop is not necessary. Unfortunately, 99% of the time this is not the case. Typically you will 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 a 1 3 4" (6.35mm) collet, it can grip workpieces that have bores from 1.749" to 1.765" (6.10mm to 6.96mm) in diameter. Will I damage the expansion collet if I close the collet without a workpiece on it? No. The Sure-Grip System is designed to eliminate this problem. The draw bar will contact the face of the arbor before the collet can be over-expanded. 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 hexshaped part? Yes. Hex and square collets are available. 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 OD of a workpiece. We recommend that you use the Model S" Precision-Style Expanding Collet for heavier stock removal on parts with bores less than 1 2" (12.70mm) in size. 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 arbor assembly may result.
