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. Use of this device will provide a jaw surface true to the machine centerline, reduce set-up times, and increase up-times for running machined parts. They provide uniform pressure on jaws for a more consistent bore on large-diameter chucks. Soft jaws, round jaws, and full-grip jaws can be precisely machined for a firmer grip on the workpiece. They compensate for “jaw lift” even in worn chucks, which yields better part concentricity. 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 in. in diameter. Both styles feature no-tools attachment. Dillon jaw-forming rings are a high-quality product that will ensure years of quick, stress-free set-ups when paired with Dillon jaws.
