Difference between grinding and milling The abrasive grains in the wheel are much smaller and more numerous than the teeth on a milling cutter. Cutting speeds in grinding are much higher than in milling. The abrasive grits in a grinding wheel are randomly oriented . A grinding wheel is selfsharpening. Particles on becoming dull either fracture to create new cutting edges or are pulled out of ...
