Description
Version - image:
Individual adjustment of combined jaws.
Centring adjustment of jaws.
Centring adjustment of jaws.
Application:
Combined clamping option due to two different jaw adjustments:
a) Self-centring adjustment of the base jaws (geared scroll);
b) Individual adjustment of top jaws.
This allows irregularly shaped components to be clamped as if to a face plate. The gear scroll for jaw adjustment is through-hardened, the flanks of the scroll and of the bottom jaw teeth are ground on both sides.
With cylindrical centring mount to DIN 702-4. The chuck is fitted to a flange from the rear by means of screws and this flange is then mounted on to the lathe spindle.
