Today's Hardinge 5C collet is the result of over 100 years of experience in serving the needs of the machining industry. The Hardinge 5C collet is manufactured to exacting standards from special alloy steel. Threads are heat treated and the body is spring tempered to assure accuracy and durability at low cost. Hardinge 5C Collets offer a through-capacity up to and including 1-1/16" round, 7/8" hexagon, and 3/4" square. The 5C collet includes precision internal threads for the Hardinge threaded positive stops. Exceptions are .985" round and over, .844" hexagon and over, and .704" square and over. For most applications, the 5C-SC step collet will provide both internal threads and desired size (note: number and letter sizes do not have internal threads).
Special-Accuracy 5C Collets are available. When held in a Hardinge Super-Precision® spindle, they are guaranteed to have a maximum TIR of .0002" for 5C round collets, and .0005" for 16C, 20C and 25C round collets over 3⁄16" (4.76mm) to the collet’s capacity measured 1" from the face of the collet.
Collet Concentricity Inspection
Concentricity is measured in terms of Total Indicator Runout (TIR) using a Hardinge Super-Precision® spindle. A gage pin is inserted in the collet and the TIR is measured at a set distance from the spindle face, depending on the order hole size, using a .00005" dial indicator. You can be assured of a qualified inspection – standard 5C collets will run .001" or better, while special accuracy collets will run .0002" or better. This assures that the collet will hold your part consistently during your specified machining operations.
