  • Patent number: 6315106
    Abstract: A machining system includes a plurality of machine tools, a transfer apparatus configured to move a workpiece and a plurality of chip conveyors. Each of the plurality of chip conveyors includes a feeding device, a discharging opening and at least one of a first opening and a second opening. The first opening communicates with the discharging opening of an adjacent chip conveyor of the plurality of chip conveyors. The second opening receives chips generated by at least one of the plurality of machine tools. The discharging opening is for discharging the chips in the chip conveyor. The feeding device is configured to move the chips in the chip conveyor toward the discharging opening. A total length of the chip conveyors is easily regulated by changing the number of the chip conveyors so that the machining system is easily and quickly reconstructed.

  • Patent number: 6190294
    Abstract: A horizontal machine tool has a spindle head which supports a horizontal tool spindle. The spindle head is guided on a top surface portion of a base such that the spindle head is movable in two horizontal directions X and Z. A workpiece support for supporting a workpiece on its upper end is guided on the vertical front face portion of the base for movement in a vertical direction Y. When the spindle head is located at a machining position at the center in the X direction, a pair of guide portions of each of a front/back guide mechanism for the spindle head and a vertical guide mechanism for the workpiece support body take symmetrical positions with respect to a vertical plane including the axis of the tool spindle. A first index member and a second index member for supporting the workpiece are provided on the workpiece support body. Therefore, all surfaces of the workpiece excepting an attachment surface can be machined while being directed to a tool on the tool spindle.

  • Patent number: 5836573
    Abstract: A clamping system has a clamping device inserted in an installing hole formed in a fixture base, a cylinder unit for operating a clamp and a detection unit for detecting operation positions of the clamp, both of which are formed in the clamping device. In the fixture base, there are formed clamping fluid supplying passages for supplying clamping fluid and detection fluid supplying passages for supplying detection fluid, in which pressure switches are provided. And also, in the clamping device, there are formed detection fluid supply passages and clamping fluid supply passages. When the clamping device is inserted into an installing hole formed in the fixture base, the clamping fluid supplying passages are communicated with clamping fluid supply passages, and also the detection fluid supplying passages is communicated with the detection fluid supply passages through nozzles formed in the cylinder unit.
