Grinding is a method of reducing the size of hard materials or sharpening tools, generally accomplished in several stages. To produce desired fineness of end products, grinding is done after crushing.

Grinding machines generally work on a similar principle. They use abrasion to change the form of metal and metallic items. This means instead of cutting a work piece, its form is changed by rough spinning wheels that erode the material.

10%Abstract. There are many types of grinding: "precision" and "rough," internal, external, surface, centerless; using wheels or belts; and conventional or "super" abrasives. I believe they all act the same. When a moving abrasive surface contacts a workpiece, if the force is high enough, material will be removed from the part and the ...

External cylindrical grinding is one of the most common grinding processes and is mainly used for grinding rotationally symmetrical workpieces.
