Self-centering jaw forming rings

Dillon Self-centering jaw forming rings, or jaw boring rings, attach to the front of jaws without tools so installation is fast and simple, and set-up times are slashed, the company says.

Additionally, they provide a jaw surface true to the machine centerline and increase up-times for running machined parts. Uniform pressure on jaws produces a more consistent bore on large diameter chucks. Compensation for “jaw lift” even in worn chucks, yields better part concentricity. Soft jaws, round jaws, and full-grip jaws can be precisely machined for a firmer grip of the workpiece. Dillon Jaw Boring Rings are available in diameter-specific models or adjustable models to bore a range of chuck diameters.

Chuck-diameter-specific versions, and adjustable boring rings are available from 6-18-inches in diameter. Both styles feature no-tools attachment.
