A friable grinding wheel has fresh cutting crystals exposed continuously to the workpiece making it the fastest cutting abrasive. Semifriable abrasive grains do not fracture as readily as friable grains. This results in longer grain life during grinding, but semifriable grains do not cut as freely as friable grains.

GRINDING PARAMETERS CONVERSION CALCULATOR

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.

Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheels, and the speed of their rotation relative to each other determines the rate at which material ...
