Dillon Jaw Forming rings, or Jaw Boring Rings, provide uniform pressure on jaws, allowing soft jaws or full-grip jaws to be precisely machined. A firmer grip of the workpiece allows for a more consistent bore, especially on large diameter chucks.  Dillon Jaw Forming Rings provide a jaw surface true to the machine centerline, reduce set-up times, and increase up-times for running machined parts. These proven, self-centering rings attach to the front of jaws without tools, making installation simple and fast. They compensate for “jaw lift” even in worn chucks, which yields better part concentricity. Available in diameter-specific models or adjustable models to suit a range of diameters, they are ideal for CNC lathes.

 

Chuck-diameter-specific versions are available for 5, 6, 8, 10, 12,15, and 18” chucks. Adjustable boring rings are available for 5-8, 6-10, and 9-12” chucks. Either style features no-tools attachment. Dillon jaw forming rings are a high-quality product that will ensure years of quick, stress-free set-ups.
