Abstract (en)

An engine valve (3) which comprises a head (3b) and a stem (3a) is put and ground between the grinding (4) and adjusting (5) wheels in a centerless grinder. The head (3b) is projected at one end of the engine valve (3) from the grinding wheel (4). Thrust force is given towards the projected end of the engine valve by inclining the adjusting wheel (5), and the projected end of the engine valve (3) is supported by an engaged portion of a stopper device (13). The stem (3a) of the engine valve (3) is accurately ground by the width of the grinding wheel (4) from the projected end of the engine valve (3). <IMAGE>
