Polishing Stavax Moulds - Technical Article
Polishing Stavax is not easy and takes many years of experience. Bohler M 333 is the easiest stainless steel to polish but is still not easy
- If machined finish is of reasonable standard, start with a 320 Grit abrasive (Gesswein stones or paper) finish and reduce down to 2000 Grit finish
- The problem lies with the glossing. 2000 Grit paper is very fine, and the next stage is to use is a hard 1” felt bob with Kemet 14-KD-C2 Diamond paste and very slow revs on the NSK Espert power hand tools When you believe you have taken out the 2000 Grit paper marks then stop, don’t over polish.
- Now use a soft 1” felt bob with Kemet 3-KD-C2 Diamond paste, again slow revs, and take out the 14-KD-C2 Diamond paste marks.
- Finally use a tissue with Kemet 1-KD-C2 Diamond paste and a little lubricating fluid and hand polish to a finish.
