Options and special information
The 6-jaw compensation chuck is based on the principle of chuck jaws that oscillate in pairs. Two base jaws are always connected with a pendulum body. This ensures workpiece centering between six contact points, which can be adjusted in pairs. Even raw parts can be centered without distortion of the workpiece.
For specific applications, the pendulum compensation can be blocked resulting in the centric clamping of the jaws.
