Evan Doran. Assistant Editor. On its surface, grinding seems simple: a machine takes a rotating tool (usually a wheel) with abrasive grains and applies it to a workpiece's surface to remove material. Each grain is its own miniature cutting tool, and as grains dull, they tear from the tool and make new, sharp grains prominent.

Machining is the process by which a piece of raw material is cut and shaped into the desired form. Most machine tools rely on subtractive machining, removing material by cutting or grinding. Machine tools, of various kinds, have been in use for centuries or even longer. The metal lathe is one such machine.

Grinding machines aren't a new invention. They've been around for centuries, with some of the first grinding machines consisting of a pedal that, when stepped on, turns a grinding wheel. Pedal-powered grinding machines are rarely used today. Rather, most modern grinding machines are now powered by electricity.

The first American gristmill (which is a mill for grinding grain, especially the customer's own grain) was built in Jamestown in 1621. Prior to that, the Native Americans ground corn by hand usually with a mortar and pestle, as did the very early settlers. In 1631 a gristmill was built in Watertown, Massachusetts, and in 1633 gristmills were ...
