Use:
- for workpiece clamping
- no axial movement while chuck is clamping suitable for very short workpieces because the power is transferred from the clamping sleeve taper to the taper of the collet on their front part.
Bore patterns:
smooth
Hardness:
The collets are made from special spring steel. Where possible, by partial tempering, the hardness of the taper and the clamping bore is HRc 58 - 60.
Special features:
- the complete set of collets is adjusted in its length
- all collets with high running concentricity
- additional cross keyway in shank on request
- with profiled bored collets, position of shank keyway in relation to profiled bored bore is very important
- square, hex. and other profi led bored bores are eroded – higher running concentricity
- clamping bore expanded by 0.5 mm
- workpiece stops can be supplied
