What grit sequence do you use for fine grinding? ATM
Sep 09, 2013 · What grit sequence do you use for fine grinding? posted in ATM, Optics and DIY Forum: A few centuries ago when I was young I used WillmannBells 120, 220, 320, 500 grit SiC, then 12 and 5 micron aluminum oxide. Seems an awful lot of sizes compared to what others have recommended. Mel Bartels uses just 120, 220, 500 SiC and 9 micron Al2O3.
