ABSTRACT:
For grinding one of axially spaced journal sections of a workpiece each having a cylindrical surface and a pair of shoulder surfaces extending radially outward from the opposite end portions of the cylindrical surface, a rotating grinding wheel is advanced to grind the shoulder surfaces of one journal section and then to grind the cylindrical surface of the one journal section. At the end of the cylindrical surface grinding, the grinding wheel is retracted by a fixed distance at a slow feed rate and is further retracted at a rapid feed rate. A rest shoe provided on the side opposite to the grinding wheel with the workpiece therebetween is advanced to an advanced position where the rest shoe contacts with another journal section axially spaced from the one journal section to decrease the flection of the workpiece caused by grinding resistance and is retracted away from said another journal section when the fixed-distance retraction of the grinding wheel is completed.
