Hollow Center Power Chucks

Additional Details

Manufactured from high-grade alloy steel, all the sliding surfaces of this chuck are hardened and ground for accurate running and long service. Standard hard jaws and soft jaws are provided for chucking the special components.

The Wedge design of the chuck has a self-locking feature, that prevents accidents and it does not loose its gripping power even at cutting loads. Each base jaw is provided with a lubricating nipple to ensure long and trouble free life.

Not only are these chucks compact, rigid and light in weight, but they also offer a powerful grip along with repeatability. They are ideal for high speed chucking, bar chucking, universal machining and especially suitable for CNC machines.

 These chucks are activated by rear mounted hydraulic or pneumatic cylinders via the draw bar passing through the spindle bore. Since it is important that the cylinder should provide the correct operating force to match the chuck, the supply of line pressure to the cylinder should be adjusted accordingly.

 Special chucks with large bore (approx. 15% larger) can also be supplied for higher speed and gripping force.
