  • Double disc surface grinding machine and grinding method
    Patent number: 9889532
    Abstract: A double disc surface grinding machine (10) includes work holding section (65) for holding an inner circumferential surface of an annular work (W) at a plurality of locations. The work holding section (65) includes a plurality of holding members (66) extending radially as viewed from a rotation shaft (46). Each holding member (66) is movable outward and inward radially of the rotation shaft (46), and is contactable to the inner circumferential surface of the work (W). The position adjustment section (76) connects the rotation shaft (46) and the work holding section (65) with each other, and adjusts a position of the work holding section (65) in the radial direction of the rotation shaft (46). While the inner circumferential surface of the work (W) is held by the work holding section (65), the rotation shaft (46), the position adjustment section (76), the work holding section (65) and the work (W) are rotated integrally with each other around the rotation shaft (46).
