Dillon Manufacturing Inc. has introduced self-centering Jaw Forming Rings, or Jaw Boring Rings, that install without tools.
The Jaw Boring Rings attach to the front of jaws without tools so installation is faster and simpler, and set-up times are reduced. 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.
The boring rings 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 of the workpiece. They compensate for “jaw lift” even in worn chucks, which yields better part concentricity. They 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.
Dillon says the new jaw forming rings are a high quality product which will ensure years of quick, stress-free set-ups when paired with Dillon jaws.
