ABSTRACT:
A method of grinding plural journal portions of a workpiece with plural grinding wheels. In the method, a pair of work rests are used to support two selected journal portions, and the selected two journal portions have a larger initial diameter as compared with the rest of the journal portions. Initially, the selected journal portions are ground without using the work rests. When the diameter of the selected journal portions becomes substantially equal to the diameters of the rest of the journal portions, the work rests are advanced to support the selected journal portions. After that, the grinding wheels are again advanced to grind all the journal portions.
