The CB-NK series collet chuck is a Pull Back design that offers the added flexibility of being able to mount part stops inside the chuck body for easy conversion from bar to chucking work.
CB-NK Features
- Pull Back design maximizes the efficiency of the clamping system by concentrating all forces in the direction of the spindle for highest accuracy and greatest overall rigidity
- Low profile OD and short overall length provides increased tool clearance and maximum utilization of the machine's Z axis
- Radial adjusting screws
- Lubricated-for-life design requires minimal maintenance
- All components hardened and precision ground for highest accuracy and long life
- Removable stop plates and stop housings can be mounted inside the chuck body for chucking applications requiring end stops or part ejectors
- Spindle speeds up to 6,000 rpm
