• ### GRINDING PARAMETERS CONVERSION CALCULATOR

CALCULATING SFPM The performance of grinding wheels and quality of the finished workpiece is affected by how fast the abrasive grains sweep over the workpiece. That speed affects surface quality, workpiece burn, material removal rates, and other factors. Since the speed of the abrasives on the wheel perimeter depends upon the diameter of the wheel, RPM isn't a useful measure.
