Abstract:

A grinding machine is such that a pair of workpiece support devices (12, 13) which clamp and rotate a workpiece (W) are provided on a bed (11). A pair of saddles (14) are provided on the bed (11) in such a way as to be movable along the rotational axis of the workpiece (W). Grindstone bases (16) provided with rotating grindstones (16c) and drive mechanisms (16d）are supported on the saddles (14) in such a way as to be movable along a direction which perpendicularly intersects the movement direction of the saddles (14). There is provided a partition structure (20) which consists of a fixed cover (21) and a flexible cover (22), and serves to partition a processing region (T) for the purpose of sealing off the same so that the clamping portions (12a, 13a) and the rotating grindstones (16c) of both of the workpiece support devices (12, 13) will be located inside the processing region (T), and that bearing sections (12b, 13b) and driving sections (12c, 13c) of both of the workpiece support devices (12, 13), as well as bearing sections (16b) and driving sections (16d) of both of the grindstone bases (16), will be located outside the processing region (T).
