SPANNTOP® combi style chucks with pull-back clamping, incorporate an end stop for chucking applications. The end stop is easily removed from the front, making the combi chuck ideal for bar work as well.

The end stop is fixed in the chuck body. During clamping the workpiece is pulled firmly against the stop as the clamping head (collet) is actuated. This important feature assures positive workpiece location, together with increased overall rigidity. Ideal for a short chucking workpiece.

Combi Pull-Back with Endstop, for chucking and bar feeding applications

• Clamping on the entire circumference
• Rigid clamping due to the continuous pull back force against the endstop(Important for parts with limited clamping area.)
• Minute loss of centrifugal clamping force.
• Extremely rigid
• Excellent repeatability after changing of the clamping head (collet)
• Simple mechanics, therefore little loss of power.
• Maximum clamping force
