An automatic six-face machining system has been proposed in which a jig plate and a workpiece are gripped by a second spindle and the remaining five faces are machined (see Patent Document 2). According to this, the supply and discharge of workpieces are automated by robots, but the setup time for supply and discharge of workpieces tends to be long, the actual processing time is shortened, and more efficient processing is performed. Not.

According to this, although there is an advantage when machining a rod-shaped workpiece, it is poor in versatility.

A conveyor device can be arranged as the chip discharge mechanism 70.

  19 to 21, as shown on the right side of FIG. 22, the main shaft (quill) 31 adds the workpiece mounting width A and the play widths B on both sides of the workpiece mounting width A. The movement width C in the U-axis direction, which is the combined total length, can be moved. According to this configuration (quill movement + U-axis type shown on the right side of FIG. 22), both sides in the X-axis direction (same as U-axis direction) compared to a simple quill movement type (configuration shown on the left side of FIG. 22) It can be made into a compact shape shortened by dimension D. The dimension D is the sum of the half of the workpiece mounting width A and the play width B, and the overall size of the apparatus can be reduced by the length of 2D = A + 2B.

  That is, according to the embodiments of FIGS. 19 to 21, the apparatus can be greatly downsized without reducing the work size that can be processed. In particular, since the present embodiment has a configuration in which two work holding device sections are provided, the effect is increased. Further, by operating both the X-axis and the U-axis, it contributes to shortening the machining time.

  As described above, the present invention has been described in various ways with preferred embodiments. However, the present invention is not limited to these embodiments, and many modifications can be made without departing from the spirit of the invention. That is.
