Abstract: Provided is a bed (10) used for a grinding machine (1). The bed has a bed front part (11) on which a workpiece support device (20) is mounted and a bed rear part (15) on which a grinding wheel stand (30) is mounted. An upper portion (12) of the bed front part (11) protrudes further to both of the left and the right than a lower portion (13). A front installation section (17a) is provided in the lower portion (13), and in the bed rear part (15), two rear installation sections (17b) are provided spaced apart from each other in the left-right direction. In this configuration, resonant vibration of the bed (10) due to the vibration of the grinding wheel stand (30) can be suppressed.

Abstract: This scattering prevention structure of a grinding machine has: a pair of supporting tables; an X axis saddle, which supports a grinding head such that the grinding head can freely move in the advancing/retracing direction with respect to a workpiece; a Z axis saddle, which supports the X axis saddle such that the X axis saddle can freely move in the rotating axis direction of the workpiece; and a grinding stone cover. The grinding stone cover is fixed to the Z axis saddle such that the grinding stone cover opens in a machining region, and the grinding stone head can freely move, with respect to the grinding stone cover, in the advancing/retracting direction with respect to the workpiece, by having the accordion cover therebetween. With this configuration, the size of the machining chamber is reduced, and shielding performance is improved.
