Tips for Trouble-Free Centerless Grinding
The roll and wheels should run in the same direction at point of contact – "unidirectional." For peak sharpness of the wheel, run the diamond roll at 80% of grinding wheel speed measured in sfpm. Traversing the diamond roll across the wheel at 6-12 ipm provides a sharp, aggressive wheel. The dress comp should not exceed 0.001″.
