PURPOSE:To enable the grinding of a concrete surface larger than the width of a cutter without need for moving a machine body by installing said cutter to said machine body via a vertical feed mechanism and a lateral feed mechanism which are the combination of vertical and lateral feed guide rails. CONSTITUTION:A cutter frame 16 on which a cutter 10, a guide roller 15, a hood 20, etc. are placed, is installed on a vertical feed guide rail 30, enabling the cutter to move in the vertical direction. Further, the frame of this vertical feed guide rail 30 is installed on a lateral feed guide rail 32, thereby, enabling the grinding of a surface larger than the width of the cutter, without need for moving the position of a machine body. |
