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 Willmann-Bells 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.

Grinding Optical Fine - eurosofa-direct.eu
Automating Fine Grinding of Precision Lenses. Fine grinding, typically the last step before polishing, is now a relatively labor-intensive task that drives up the cost of precision optics. Fine grinding is a sensitive operation. The relatively fast speed of the grinding tool must be slowed down as it approaches the lens for fine grinding.
Grinding & Polishing Discs - Kemet
Fine grinding discs need diamond abrasive added during use. Because of their effectiveness in bringing diamonds in contact with the sample, they do neither require large amounts of diamonds nor any run-in time. With diamond suspensions you should dose about 0.5 ml/min on a 250 mm disc. Less on a 200 mm disc and more on a 300 mm disc.
