Feb 16, 2014· We use a 46G wheel for that. With a manual surface grinder I''d rough in .005 away keeping it cool, let the coolant work for you. We take up to .400 a pass with no change in Rockwell. It''s all about grinding style/method. I''ve seen people mess a part (rockwell/cracks/etc) taking off less than .005 while others can do .250 + with no problems.

In Brinell hardness testing, a hard metal ball (carbide ball) is pressed into the material surface to be tested within approximately 10 seconds as the force increases. The applied test force is maintained for 15 to 20 seconds so that the material can settle during this time and the measurement provides reproducible and comparable test results.
