Surface Grinder table speed Practical Machinist

2019-9-7  I have a Chevalier fsg-1224ad surface grinder with hydraulic table feed and automatic cross and downfeed. I have been grinding only some steel for now and it seems that when i take the last few 0.0004" passes and run it with high table speed, i get better surface finish.

How is grinding wheel speed calculated?

2020-6-7  Accordingly, how is grinding wheel consumption calculated? 1. Wheel Speed. Average rpm = sfpm / (π/12 × DH) Wheel diameter at half of wheel life (DH) (in inches) = Start Dia. Wheel Wear per Grind Cycle = Continuous Dress Amount per Revolution of the Wheel (CD) × rpm × Wheel Travel / Table Speed.
