Draw-back collets with a hardness of HRc 45 are available for collet types 349 E, 358 E, 369 E, 363 E, 364 E, 366 E, 367 E, 385 E and 386 E with various head sizes.
Use:
Emergency collets are used for holding smaller series workpieces when no standard collet is available. Unlike the standard collet, with its hardened taper and clamping bore, emergency collets only have a hardness of approx. HRc 45. The customer can therefore enlarge the bore of the collet.
To enlarge the bore, the emergency collet is clamped on a bolt in the rear of the clamping bore or on pins in the slots and turned out in this position.
Note: The centrifugal force resulting at high speeds can lead to a lessening of the clamping power and, in extreme case, breaking of the collets. Please follow accident-prevention instructions.
Special features:
Deadlength collets (pic. 1) with a hardness of HRc 45 are available for collet types 140 E, 148 E, 161 E, 163 E, 173 E and 185 E, further types on request.
