SK collet chuck CB-NK

millingquick-changeradial

NK series chucks are a pull back design with the added flexibility of being able to mount end stops inside the chuck body for easy conversion from bar to chucking applications. The collet is coupled directly to the draw tube connector. As the draw tube is actuated the collet is drawn into the tapered seat efficiently translating draw tube force into maximum clamping force. • 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 to true-up the chuck assembly within .0002” (0.005mm) • 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
