Hardinge® Sure-Grip® Expanding Collet Systems offer solutions to difficult machining problems for turning, milling, grinding, assembly and automation applications. Hardinge is the expert when it comes to exact part length control, patenting the first Dead-Length 5C and 16C collets used for high-production manufacturing. Our Sure-Grip Expanding Collet Systems have true part length control built into its double-angle design, assuring 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. 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.
