There is disclosed a boring machine capable of achieving high processing precision and high processing efficiency. A table is mounted on a bed for reciprocal movement in right and left directions. A workpiece fixing device for fixing workpieces W of a semi-cylindrical shape is mounted on the bed. Cutting tools P and Q for cutting the workpieces W, a workpiece carry-in device and a workpiece carry-out device are provided on the table. The table is moved to a left side, and the workpieces W are placed on the workpiece carry-in means. Then, the table is moved to a right side to transfer the workpieces W to the workpiece fixing device. The table is again moved to the left side, so that each workpiece W is subjected to a boring processing by the cutting tools P and Q. The workpiece carry-out device receives the processed workpieces W, and then the workpieces W are unloaded from the boring machine by a workpiece unloading device, and are fed to a subsequent step. |
