  • A WORKPIECE HOLDING ASSEMBLY FOR A GRINDING MACHINE AND GRINDING METHODS
    Publication number: 20220388107
    Abstract: A workpiece holding assembly (20) comprises a magnetic chuck (22), and first and second separate sets of workrests for engaging with the outer circumferential surface of an annular workpiece (40, 60). The workrests are configurable such that when the outer circumferential surface of the workpiece (40, 60) is ground with the chuck Urotating in one direction, the outer circumferential surface is only urged in contact with the first set (26, 28) of workrests, and when an inner circumferential surface of said workpiece is ground with the direction of rotation of the chuck reversed, the outer circumferential surface is only urged in contact with the second set (30, 32) of workrests. Grinding methods using such a workpiece holding assembly are also described.
