The precision design attracts an additional charge
Use:
- for workpiece clamping
- for bar or chuck work
- clamping range 2 mm
- no axial movement while chuck is clamping
- can be exchanged with DIN 6343 steel collets
- completely sealed against coolant and swarf
Hardness:
The segments of multi-range collets are made from a special tool steel. The hardness is approx. HRc 60.
Taper angle of the clamping sleeve:
The taper of the clamping sleeve must exactly match the taper angles of the collets given in the tables, otherwise the clamping segments will not clamp the workpiece along its entire length.
Stops for collets:
If stops are used, the rear of the clamping segments must be supported if the clamping length is short.
