Gear teeth can be produced entirely by grinding, entirely by cutting, or by first cutting and then grinding to the required dimensions. Usually, gear grinding is performed after a gear has been cut and heat-treated to a high hardness; grinding is necessary for parts above 350 HB (38 HRC), where cutting becomes very difficult.
