Description of the Related Art When performing cutting, the cutting edge is usually cooled to delay the progress of tool wear, to provide lubricity in order to reduce cutting resistance, and to discharge scraps generated by the processing. Supply cutting oil to the cutting edge. Conventionally, this cutting oil is generally supplied from a hose, a nozzle or the like through a turret or the like of a machine tool so as to be interlocked with the feeding of a tool. However, in such a method, it takes time and effort to adjust the injection position in order to properly inject the cutting oil into the cutting edge, and it is necessary to take a certain distance from the injection port to the cutting edge, so the cutting oil is effectively applied to the cutting edge. It was difficult to supply.

ている。In order to solve such a problem, for example, in an inner diameter boring bit, as shown in Japanese Utility Model Publication No. 6-41765, a method is provided in which a cutting oil supply passage is provided in the shank and the cutting oil is supplied to the cutting edge through the inside of the holder. As disclosed in Japanese Utility Model Laid-Open No. 63-97401, a small hole for cutting oil supply is made to penetrate in the vicinity of the cutting edge of the throw-away tip, and a supply passage is provided inside the holder so as to communicate therewith, and the chip is scooped. A method of supplying cutting oil to the surface has been proposed.

ある。By the way, in the above-mentioned tool, in the case of the method of providing the cutting oil supply hole in the shank as in Japanese Utility Model Publication No. 6-41765, the distance from the injection port to the cutting edge is at least within the tip. There is no choice but to make it larger than the contact circle size, and the supply path inside the shank is generally 3 mm.
Since there is no choice but to use a small diameter of φ or less, the pressure for cutting oil supply may drop, and effective supply may not be possible.

The existing standardized tip cannot be used, and since the hole is opened near the cutting edge, the degree of freedom in designing the chip breaker is reduced. Further fair fair 6-41765
Since it is unavoidable to use a small-diameter flow path as in the publication, the pressure of the cutting oil supply may drop, and effective supply may not be achieved.

自由に選択できる。If the crank bite set as described above is used, the cutting oil is supplied from the flow path inside the holder main body to the cutting edge through the attachment hole of the throw-away tip, the small hole at the tip of the pressing piece. Therefore, the distance from the injection port of cutting oil to the cutting edge is about half the size of the inscribed circle of the tip, and the small hole at the tip of the small-diameter presser piece can be made extremely short, and the remaining flow path, which is the throwaway path. Since the mounting hole of the tip and the flow path inside the holder body can be made relatively large, the pressure drop of the cutting oil can be suppressed to the minimum, and the cutting oil can be effectively supplied. Since it is possible to use a standardized throw-away tip having a mounting hole, the tip breaker can be freely selected according to the application.

Since it can be supplied from the hole to the cutting edge, the distance from the cutting oil injection port to the cutting edge can be shortened, and the size of the flow path can be made relatively large except for the small holes of the pressing piece, so the pressure drop of cutting oil is also minimal. You can limit it. Therefore, the cutting oil can be supplied to the cutting edge more effectively than before, and the effects of improving the tool life, improving the chip discharging property, and the like can be obtained. Particularly, when a high-pressure cutting oil having a pressure of 10 kg / cm 2 or more is supplied, the effect is further enhanced.

Also, by interposing a tip sheet with a mounting hole between the throw-away tip and the seat bottom surface, even if the tip breaks, the holder will not be damaged, and even if the tip sheet is replaced, it can be used continuously, so it is economical. is there. Furthermore, between each part,
If a sealing material such as a rubber O-ring is provided, it is possible to prevent leakage of the cutting oil from each clearance, so that the cutting oil can be supplied more effectively without causing a pressure drop.
