Does anyone have a recommended process for polishing hard chrome? We have four hydraulic cylinder piston shafts (40mm in diameter) that have been hard chrome plated. The current finish is 10 uin Ra. The seal supplier recommends we a 6 uin Ra finish, so we have to do some polishing.
How do you polish this stuff? We've tried various approaches, but to limited success. Five micron diamond paste applied using a wood backer worked the best, but took about 2 hours on the lathe to do a single rod. There has to be a better way!
Thank you!
