Throughfeed grinding (also known as thrufeed grinding) is the process of feeding the part through the regulating wheel and the grinding wheel. Throughfeed grinding is used for simple cylindrical parts. The regulating wheel is angled to the grinding wheel, with the inlet side having a larger opening. The part is placed onto a conveyor and the conveyor guides feed the part into the wheels. The part is then pulled through the wheels by the rotation of the regulating wheel and the grinding wheel and exits on the opposite side.
