通じて刃先(チップ)へ注入され、刃先の潤滑。[Detailed Description of the Invention] Boring and Tre-pa is a representative of the so-called deep hole drilling method in which the depth of the hole is considerably deep compared to the hole diameter.
There is nning As5ocation BTA processing. A feature of this machining method is the cutting oil supply system, in which high-pressure cutting oil is injected into the cutting edge (chip) through the gap between the inner wall of the hole and the outer circumference of the tool to lubricate the cutting edge.

ーズな流出を図っている。It is cooled and then discharged out of the hole through the inner circumference of the tool (cylindrical). Chips generated at the cutting edge are flushed out of the hole at the same time as the cutting oil is discharged. Efforts are being made to ensure smooth outflow by optimizing the diameter.

る。The present invention is characterized in that a spiral groove is carved on the inner circumferential surface, outer circumferential surface, or inner and outer circumferential surface of the boring bar of the BTA machine in the direction opposite to the tool rotation direction on the inner circumference and in the same direction on the outer circumference as seen from the chip side. Regarding all the features of the tool f), in the conventional method, when the machining efficiency is increased and the amount of chips generated increases, they cannot be flowed out by the cutting oil pressure, and chips form inside the boring bar and machining becomes impossible. 2. In the present invention, the spiral groove is carved on the inner circumference of the boring bar as described above, so the flow velocity of the cutting oil increases due to the screw effect of this groove, and as a result, the chip discharge ability is high.19. It aims to provide a complete range of tools that can improve efficiency, and can be applied to BTA tools.

回転させると。An embodiment of the tool of the present invention will be described with reference to FIG. FIG. 1 is a complete illustration of an embodiment of the tool of the present invention. A chip 1 is fixed to a head 3, and a boring bar 4vc is attached to the head 6. When the boring bar 4 is rotated fully.

刻んでもどちらでもよい。As the tip rotates, the entire cutting process is performed. The annular pressure type 6 is pressed against the work piece 21/j, and there are O-rings 9, 10 between the pressure type and the work piece and between the pressure type and the boring bar.
It is sealed with. Pressure head VCil''j: A cutting oil injection lower is provided.The above structure is the same as the conventional structure, but in the present invention, a spiral groove 5 is carved on the inner surface of the boring bar 4.This spiral groove When viewed from the chip side, the direction is opposite to the tool rotation direction.In other words, when following the entire helical tool rotation direction, the groove should run in the direction opposite to the chip.Note that the groove may extend over the entire length of the boring bar or only partially. It doesn't matter which one you carve.

、その結果切屑排出能力が高するものである。At this time, chips generated by cutting with the chip are also discharged to the outside through the entire local part of the boring bar. In the conventional method,
9. When machining efficiency increases and the amount of chips generated increases, they cannot be flowed out by cutting oil pressure.9. Chips accumulate inside the boring bar, making machining impossible. In the present invention, since the spiral groove is cut into the inner circumference of the boring bar as described above, the flow velocity of the cutting oil is increased due to the screw effect of this groove, and as a result, the chip discharge ability is increased.
