The brilliance of this design is not immediately noticeable: One movement of the chucking cylinder and the clamping unit moves forward, the clamping head clamps and the work piece is pulled back onto the end-stop. Perfect!
The chuck provides very high clamping forces and therefore the possibility of machining at very high cutting speeds »between centers«. Even though its size is much smaller than usual, it still has the famous SPANNTOP »bite«. A simple, economical standard clamping cylinder is all that is required to accomplish this.
