Cylindrical grinding

Workpieces that are provided with an excess hard chrome plating must generally be finished to the prescribed dimensional tolerance. In order to be able to supply our customers with ready-to-install machine parts, we have a precision cylindrical grinding shop so that we can pregrind, finish and polish parts as required.

The grinding and polishing of hard chrome plated surfaces requires special care and experience. Our mechanical machining scale ranges from rough grinding to finish polishing:

  • coarsely ground: Ra 0.7 - 1.2 µm, Rz 4 - 6 µm
  • ground: Ra 0.4 - 0.6 µm, Rz 2-2.5 µm
  • honed: Ra 0.3 - 0.35 µm, Rz 1.5 µm
  • stone polished: Ra 0.02 - 0.04 µm, Rz 0.2 - 0.4 µm, Rt 0.4

Key data for workpieces that we can cylindrically grind:

  • max. length: 4,000 mm with
    max. diameter: 500 mm
    or
  • max. length: 3,000 mm with
    max. diameter: 600 mm
