Definition. Gear grinding is a hard finishing method for gears, using tools with a specific geometrical profile. It is divided into two main groups: generating grinding and profile grinding, relating to the manufacturing of the tooth flank.

Grinding is used to finish workpieces that must show high surface quality and high accuracy of shape and dimension. It has some roughing applications in which grinding removes high volumes of metal very rapidly.

Gear grinding is one of the ways in which a gear being produced is finished. Gear grinding is used to remove surface materials on a gear blank through abrasion. Abrasion is conducted through rubbing of a rough surface against a piece of metal at high speeds to scrape away the material that is not needed in the gear.

The motor used in your standard grinder is a universal electric motor, which works on both DC and AC current. The motor is wound with copper wire to produce an magnetic effect on the rotor. The rotor in turn revolves at a high speed.
