Description
The chucks are designed for clamping workpieces machined on lathes of accuracy class P and B in full-scale and mass production conditions. These are power chucks; the drive is mounted on the rear end of a machine. The adjustment for a required clamping diameter is made by reinstalling hardened jaw inserts by main jaws riffling, thereby required chuck accuracy remains. The chuck is provided with oil lubricators for lubricating the working surfaces of the rod and jaws. Chucks are interchangeable with Bison-Bial chucks.
