<p>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 work; 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 work; and a grinding stone cover. The structure is provided with: a left side surface cover and a right side surface cover, which are respectively attached to the sides, on which the supporting tables face each other; a Z axis shielding cover (4), which shields the left side surface cover, the right side surface cover (3), and the grinding stone cover (18) one from another, and which has the grinding stone cover (18) attached thereto such that the grinding stone cover can freely move in the rotating axis direction; and an accordion cover (5), which is attached to the grinding stone cover (18) such that the grinding stone head (14a) fits in the accordion cover, and which shields the grinding stone head (14a) and a grinding stone cover (18) one from the other. The grinding stone cover (18) is fixed to the Z axis saddle (16) such that the grinding stone cover opens in a machining region, and the grinding stone head (14a) can freely move, with respect to the grinding stone cover (18), in the advancing/retracting direction with respect to the work (W), by having the accordion cover (5) therebetween. With this configuration, the size of the machining chamber is reduced, and shielding performance is improved.</p> |
