| Parallel Gripping The Hardinge® Sure-Grip Expanding Collet is a double-angle design that assures true parallel gripping of the workpiece with maximum torque. Generally, special restrictors are not needed when gripping a workpiece that is shorter than the collet's bearing diameter. Dead-Length® Work Stop Hardinge is the expert when it comes to exact part length control. They patented the first Dead-Length 5C and I6C 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 movementThe 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. 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. | Take advantage of these benefits on your next ID gripping job to save you time and money... • Instant centering of the arbor—no adjustment needed after mounting • Quick changeover • Wide gripping range for each collet • True parallel gripping even when gripping on half the collet body • High gripping force • Light gripping on small parts with bores down to /s" (3.175mm) • Built-in safety stop to prevent the collet from overexpanding • Exact part length control • Consistency in collet capacity for different spindle styles (interchangeable collets) | ||
