The two basic methods for gear grinding are form grinding (non-generating) and generation grinding. Form grinders use a disc wheel to grind both sides of the space between two gear teeth, and have an involute form dressed into the side of the wheel; a generating grinding wheel, on the other hand, is .
Therefore, in considering types of gears, teeth grinding is an important elememt to consider. Grinding the teeth surface makes gears quieter, increases force transmission capacity and affects the precision class. On the other hand, the addition of teeth grinding process increases cost and is not suitable for all gears.
