AIR COLLET CHUCKS

GENERAL INFORMATION
Air Operated (High Torque) for 5C & B42 Collets

The term "high torque" refers to an air mechanical collet closer which uses an air cylinder and mechanical advantage to collapse the collet. This cylinder uses air pressure to move the piston, which actuates a series of balls and incline planes to increase the force of air pressure against the collet sleeve. The air against the piston in this collet closer does not directly hold the part, but compresses the balls between the inclined planes. The movement of the balls between the inclined planes lifts the collet sleeve, collapsing the collet. This increases the holding power to well above that attained by simple air pressure. The diameter of the piston can be considerably smaller while achieving the same clamping force of a simple air cylinder with a much larger piston. The part to be machined is also held firmly against the base of the

This high torque stationary 5C air collet 
            closer is designed for use on milling, drilling and tapping 
            operations. It can be utilized as single units, or mounted to a 
            plate for multiple operations. They use from 50~100 PSI, depending 
            on the holding power necessary for a particular application.

This high torque stationary air collet 
              closer uses B-42 collets, and has been designed for use on 
              milling, drilling and tapping machines. They can be utilized in a 
              single or multiple fashion.

          This front mounted 5C air operated 
          collet chuck may be used for rotary table and single station 
          applications. The rotary gland remains in place while the air cylinder 
          rotates. This unit comes complete with air valve hoses, fittings and a 
          collet wrench. Note: for use on an SUDX or EUDX rotary table, a collet 
          chuck adapter plate is required.

The center control valve has uses for 
            multi-station fixtures of  2, 3, 4, 5, 6 or 8 positions. This valve 
            eliminates the need for rotary air couplings and cams to control 
            separate valves, and individual valves for each station. Each time 
            the table is indexed, the holding device being used opens and closes 
            in a predetermined sequence.
