た段階で所定の位置にワーク４を移送する。(Embodiment) FIGS. 1 (a) to 1 (c) are plan views showing essential parts of an example of an inner surface cutting apparatus of the present invention in the order of steps. In this embodiment, similarly to the conventional example, a cylindrical ceramic body 2 is set on a chuck 1 of an ordinary lathe, and an outer surface or an inner surface of the body 2 is abutted with a turning tool 2 for grinding an outer surface or an inner surface. And the inner surface is cut into a predetermined shape to obtain a work 4 to be used as a spacer for firing a ceramic body, for example. After that, when the work 4 is finally separated from the body 2, the first
As shown in FIG. 3A, the work receiving rod 5 made of a breathable material.
Inserted inside the workpiece 2 from the air blowing port 6 1.
Blowing compressed air of 5 to 3.0 kg / cm 2 and the work receiving rod 5
Cutting and separating while blowing compressed air from the entire outer surface of. Then, as shown in FIG. 1 (b), the separated work 4 is inserted into and received by the work receiving rod 5, and FIG.
As shown in FIG. 3, when a plurality of works 4 are held on the work receiving rod 5, the works 4 are transferred to a predetermined position.
そのため本実施例では、ワーク受け棒５の先端をワーク

インへの組み込みも簡単に行うことができる。If the pressure of the compressed air at this time is too small, it is not enough to scatter the cutting chips, and if it is too large, the pressure applied to the work receiving rod gives too much vibration to the work.
It is preferably 1.5 to 3.0 kg / cm 2 . Further, the breathable body may be a porous body having fine pores, and preferably a material having a pore diameter of 1 to 7 μm is used. Furthermore, it is preferable to prepare a plurality of work receiving rods according to the inner diameter of the work and use the work receiving rods properly according to the size of the work to be cut. Further, since the control of the insertion of the work receiving rod into the work and the start and end of the blowing of compressed air can be easily performed in accordance with the automatic control of the lathe, it can be easily incorporated into the automation line. .
