8 Principles of Centerless Grinding

 · That's why we like to say that where machining ends, the centerless grinding process begins. For instance, if you have a part that is out of round from a turning machine and the part's diameter is too small or its center is impossible to mount, you can achieve roundness through centerless grinding techniques.

abrasive machining processes

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 self-sharpening. Particles on becoming dull either fracture to create new cutting edges or are pulled out of the surface of the wheel to expose new grains.

Basic Grinding Theory 221

"Basic Grinding Theory" provides an overview of the general process of grinding . Grinding occurs at the point of contact between an abrasive wheel and a workpiece. Like any other cutting process, grinding removes material in the form of chips. In order for a wheel to grind properly, its abrasive grains must wear and self-sharpen at a consistent rate.
