Dillon Manufacturing recently introduced full grip jaws made of 1018 CR steel from 6 inches to 15 inches in diameter, with heights of 2, 4, and 6 inches.  

 

These heat treatable and weldable steel jaws allow for complete gripping of the work piece – to maintain repetitive accuracy. This type of jaw reduces distortion and provides more friction for drive during turning operations. With close tolerances and concentricity easily maintained, they are designed for applications such as valves, cylinders, specialty wheels and gears, housings and enclosures, adaptors and connectors, aluminum and steel shells, flanges, retainer rings, and other thin-walled parts such as automotive smog control air pump rotors, gas turbine parts, thin-wall tubing and cylinder liners for diesel engines and more.
