Functionality

The clamping cylinder of the machine is connected to a drawtube, and this with the drawtube connector of the chuck. By axial movement of the drawtube, the draw piece is moved forward or backward. About inclined planes on the wedge hook the axial movement of the draw piece is converted into a radial movement of the master jaws.

Through the axial movement of the drawtube to the rear, the chuck is closing on external clamping applications. By moving forward the chuck opens. On internal applications, the movements are reversed accordingly.
