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 fixture and not on a cushion of air.

 ACHT-5CA

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.

 

 ACHT-B42A

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.

 

AIR COLLET CLOSER FOR ROTARY TABLE APPLICATIONS: ACSU-5CA

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.

COLLET CHUCKS ACCESSORIES FOR ACHT MODELS CENTER CONTROL VALVES

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.
