The cut workpiece W is moved in the direction of arrow a by
from chuck 2 of the machine tool (Fig. 3C). Then, the work support 10 is moved 180 degrees in the direction of arrow C by the rotary drive device 7 at a position that does not interfere with the chuck 2 of the machine tool and the turret (not shown).
(Fig. 3D). Work support 10
is moved in the direction of arrow a2 , and the connecting rod 16 at the rear of the auxiliary shaft 12 is attached to the collect chuck 2 of the machine tool. At this time, the bar-shaped workpiece inside the collection chuck 2 to be sent out next is connected to the connecting rod 16.
pushed back by Next, by rotating the main shaft of the machine tool and rotating the auxiliary shaft 12, the back surface of the workpiece, that is, the unmachined surface, is machined (FIG. 3E). In this case, the tool rest in front of the workpiece is moved in the direction of the spindle axis, so the tools used for back machining can be the same as those used for normal machining; instead, prepare tools specifically for back machining. There's no need.

Ｈ）。 When the back machining is completed, the work support 10 is moved again in the direction of arrow a1 and the connecting rod 16 of the auxiliary shaft 12 is pulled out from the collect chuck 2 of the machine tool (FIG. 3F). The work support 10 is moved to the standby position by the rotary drive device 6 (FIG. 3G). At the standby position, the work support 10 is rotated 90 degrees in the direction of arrow c, and the collection chuck 13 of the auxiliary shaft 12 is directed downward. Next, the collection chuck 13 is opened, and the machined workpiece is dropped by its own weight into a receiving portion (not shown) (FIG. 3H).

がある。 In the above-described embodiments, the machine tool is equipped with a bar feeder and the workpiece is gripped by a collect chuck, but the present invention is not limited thereto. Therefore, for example, the chuck of a machine tool may be a scroll chuck, and various workpieces may be fed one by one from the chuck side. In this case, the process of cutting the workpiece with a parting tool is not necessary, but on the other hand, in order to automatically feed the workpiece to the chuck of the machine tool, after dropping the machined workpiece, It is necessary to grasp the material of the workpiece in the chuck of the machine and transport it to the chuck of the machine tool.
