This type of precision grinding cuts away unwanted areas while achieving the closest tolerance and high-precision surface finish. Using this technique helps you achieve quicker cycle-times, and improve the longevity of your collets and other tooling fixtures for your machining operations. Bar grinding is used when:

  • Accurate tolerance is needed.
  • Precise straightness is required.
  • Smooth surface finish is necessary.

.125 – 1.250 in diameter, and 10″ – 12′ bars
