Three-jaw ring chucks are mainly used for clamping cylindrical or ring-shaped parts at low clamping forces. In contrast to chucks for the machining of workpieces, the clamping force must be significantly lower in metrology, otherwise there is a risk of deformation of the components. By clamping by hand with the clamping ring, the components can be clamped with exactly the required clamping force. With the additionally attached spring steel dowel pins, parts with inner diameters from 2 mm can be accommodated.
The versions with base plate allow easy mounting on all ZEISS grid plates and pallets with M4/M6 threaded grid.

Scope of delivery:
- 1 set = 3 hardened inner jaws stepped with clamping pins
- 1 set = 3 hardened reversing jaws stepped
