Hello

We have a copper part that need CNC process and then hard chrome 5-8 micron.

Even though the initial surface has been well polished, hard chrome will not plate to a mirror. You have to polish it to attain the specified finish. This may require special fine abrasives. Conventional polishing pastes may not be suitable, especially for chrome deposited from proprietary chemistries that produce maximum hardnesses.

Are these pieces being polished stationary or in rotating equipment?
