  • Grinding of parts with very tight tolerances even with critical shapes (interrupted diameters, parts with holes, cuts, etc.).
  • Machine ready to work in infeed and/or throughfeed depending the required production or part batches.
  • Non-contact measuring system, for flexibility and quick set-up.

Machining operations

  • OD grinding, in infeed or  throughfeed, depending on the customer production requirements or part shape if different diameters must be ground.

Tolerances

  • Cylindricity: < 0.00006 inch.
  • Diametrical tolerance: 0.00008-0.0001 inch.
  • Surface finish: Ra 8.
