Three-Jaw Hollow Pneumatic Chuck
The chuck and the spindle are connected in accordance with national standards. The user does not need to change the machine structure. It only needs to be equipped with a flange that matches the size of the chuck.
The chuck body itself is a cylinder with a built-in piston, and the clamping and releasing action is realized by the spindle tail control mechanism.
The center of the chuck is hollow and suitable for processing longer bars.
