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
