Large Diameter Full Grip Jaws


Dillon Manufacturing, Inc. has expanded their line of full grip jaws to 24 inches in diameter.  These cast aluminum (356-T6) wrap around type top jaws can provide minimum jaw force for thin-walled parts and distribute the gripping pressure over more of the work piece’s surface - helping 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 ideal 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. 

Dillon full grip top jaws are available from stock to fit chuck sizes ranging from 6 inch diameter to 24 inch diameter, in both standard height and extra high jaws.  They can be adapted to mount both manual and power chucks. Lighter weight Dillon full grip top jaws reduce mechanical stress, for improved machine and tool life.
