18″-dia. Boring Ring

Dillon Chuck Jaws introduces an 18″-dia. boring ring. Its relatively light weight allows customers the same ease boring out 18″-dia. blank top jaws as is had when forming smaller diameters using the smaller boring rings.

Dillon jaw boring rings are easy-to-use tools that allow soft jaws to be machined precisely and thus grip the intended workpiece more firmly. These jaw rings provide uniform pressure on all jaws, for a consistent bore. Available in adjustable or chuck-diameter-specific styles, both with no-tools attachment. The Dillon jaw boring ring compensates for “jaw lift,” even in worn chucks, which results in better parts concentricity. Use of this device will provide a jaw surface true to the machine centerline, reduce setup times, and increase up-times for running machined parts.

Jaw boring rings are available for 5″, 6″, 8″, 10″, 12″,15″ and 18″ chucks, or in adjustable versions for 5″-8″, 6″-10″ and 8″-12″ chucks. Self-centering action provides equal pressure on all jaws.
