As illustrated in FIG. 4F, when the drill tip 52 drills the sintered body 200 while the rotary shaft 50 is rotated, the drilling operation of the sintered body 200 is finished, and the lead is fixed in such a state. Detaching from the rod reduces the self-weight of the support body and returns it to its original state by the upper and lower springs (see Figure 4d).

In addition, the chip generated during the drilling of the sintered body 200 by the drill tip 52 is suitably accommodated by the drill chip collecting unit 90, thereby minimizing radioactive contamination in the shielding facility.

The drill chip collecting unit 90 serving as described above has a drill chip outlet 91 formed to communicate between the first semicircular groove 821 and the second semicircular groove 831 and the base 10, and the drill. A drill chip collecting space 92 formed inside the base 10 so as to be in communication with an end of the chip outlet 91, and having one side opened, and a drill chip collecting space detachably provided in the drill chip collecting space 92. It is composed of a barrel (93).

Here, the drill chip collecting unit 90 is formed in communication with the first fixed body 82 and the second fixed body 83 and the moving plate 81 and the base 10 to the lower portion of the sintered body 200. After the chips generated through the chip outlet 91 are dropped and collected in the drill chip collecting container 93 placed in the drill chip collecting space 92, the drill chip collecting space 93 is drilled into the drill chip collecting space 92. It will be removed from and discharged to outside.
