The 1-AC Air Collet Fixture from Heinrich Company uses standard 5C collets to hold up to 1 1/8" stock or 1 7/64" through-stock. Step-chuck collets and expanding collets can also be used. A double-acting piston-type air cylinder develops holding power 18-times the line pressure. Maximum air pressure is 120 psi, and a foot switch and hoses are available with the fixture.
The collet holder is hardened and then precision ground for reliable collet closure. The base is designed to accommodate chip removal and coolant flow. The unit can be mounted horizontally or vertically.
