ABSTRACT:
Poppets of lift valves are ground in a grinding machine wherein the chuck clamps the stem midway between the head and the foot of the poppet and is indexible through 180.degree. so as to place the foot into the range of a first portion of the working surface of a grinding wheel in one of its positions and to place the head into the range of another portion of the working surface of the same grinding wheel in the other of its positions. The entire working surface of the grinding wheel is dressed during grinding of the head, and the carriage for the spindle of the grinding wheel is moved in response to signals which denote the final position of the grinding wheel upon completed grinding of the foot. The chuck is indexible in a rotary work holder whose axis coincides with the axis of the clamped poppet and is normal to the axis about which the chuck is indexed by a rack-and-pinion drive.
