る。According to the above-described chip suction device 73, when the cutter body 74 abuts the work 95 and the cutting is started by the cutting blade part 76, the small diameter part 92 at the tip of the cover 78 causes the work 9 to move.
Abut 5. Then, as the cutting by the cutter main body 74 progresses, the elastic member 84 of the cover 78 elastically deforms and follows the cover 78. Here, when the cover 78 is in contact with the work 95, the outer cylindrical member 82,
The base member 83, the expansion / contraction member 84, and the like maintain the non-rotation state due to the bearing 81 interposed. In this way, the scattering of chips generated by the cutting by the cutting blade portion 76 of the cutter body 74 is prevented by the cover 78 that covers the periphery. On the other hand, at the start of cutting, air is sucked by the suction means 79, so that the cover 78 is opened from the tip opening of the cover 78.
Air flows inside and is discharged to the outside from the suction port 87, and the air inside the cover 78 is discharged to the outside together with the chips. Also in the chip suction device 73 of the third embodiment, the same effect as that of the first embodiment can be exhibited.

That is, it has an outer cylinder part attached to the suction port, an inner cylinder part fitted inside the outer cylinder part, and a compressed air supply source for supplying compressed air, and is formed by the inner cylinder part and the outer cylinder part. When the compressed air supply source causes compressed air to flow through the passage, an air flow is generated inside the inner tubular portion in a direction away from the suction port due to the shape of the passage. Further, the cutter bodies 13, 47, 74 can be directly attached to the machine body without the holding members 14, 48.
