ABSTRACT:
A centerless grinding machine is provided with a ferris wheel arrangement having multiple, circumferential pockets in which an annular workpiece is received from a loading chute, is internally ground by a grinding wheel and is discharged into an unloading chute after grinding by indexed rotation of the ferris wheel. The grinding machine includes a stationary alignment shoe cooperating with an individual alignment shoe carried in each pocket of the ferris wheel. In the grinding position, the stationary shoe preferably is at the 3 o'clock position while the alignment shoe in the adjacent pocket is at the 6 o'clock position. The grinding wheel is positioned on one side of the ferris wheel and a workpiece driver means is positioned on the opposite side. With the inventive grinding machine, annular workpieces, such as bearing raceways, can be loaded, ground and unloaded in rapid succession with high accuracy maintained during grinding.
