Supplier must be familiar with finish callout and be able to analyze and provide certification of finish. We can provide the can already ground and re-plated, but would prefer supplier took care of everything. Finish: Ra = 4 to 8 microinch Rtm = Rz[DIN] = 40 microinch MAX Rp = 24 microinch MAX tp (bearing ratio) = 50% to 70% at .25 Rtm, relative to a reference line c = 5% tp

Polishing: Polishing and buffing processes are surface treatments performed to smooth a variety of materials. Polishing may be done for functional purposes on parts like shafts, cylinders or lenses. Polishing is also done for aesthetic purposes, for example, to achieve hi-gloss, satin or brushed finishes on materials. Polishing and buffing require the use of a buffing pad and a compound, usually containing a very fine, silica-based abrasive. Polishing is done manually, with power tools, or with fixed machines.
