この発明は、特に超精密切削加工における切屑

どによつて構成され、百分の1μmのオーダーでの
加工精度が実現されている。 In recent years, extremely high-precision optical components such as plane mirrors, spherical mirrors, and aspherical mirrors have come to be manufactured by turning using diamond vide. This processing method takes less time than polishing glass or metal, and the reflectance of the finished metal mirror is high.
It has many excellent features such as being durable and durable, and is useful for laser fusion reflectors, astronomical telescopes,
It is expected that it will be used in a wide range of fields in the future, including in line and ultraviolet telescopes, and reflectors for laser processing. Ultra-precision lathes are comprised of a high-precision rotating spindle, hydrostatic bearings, single-crystal diamond bits, and highly rigid beds, achieving machining accuracy on the order of 1/100 μm.

に対して、数μm程度以下の切込みで行なわれ、
切屑は箔状で生じる。しかして、この超精密旋削
においてはこの切屑の処理が特に重要である。 Turning using such an ultra-precision lathe is performed on copper or aluminum alloys in a dry or volatile oil environment with a depth of cut of several μm or less.
Chips are produced in the form of foil. Therefore, in this ultra-precision turning, the disposal of these chips is particularly important.
［従来の技術］
切屑の排出の良否と仕上面の品位との間には大
きな相関がある。すなわち、切屑の排出が良好で
ない場合、切屑が切削面に当つて損傷を与え、良
好な仕上面が得られない。[Prior Art] There is a strong correlation between the quality of chip evacuation and the quality of the finished surface. That is, if the discharge of chips is not good, the chips will hit the cutting surface and cause damage, making it impossible to obtain a good finished surface.

削点に向けて空気噴流や切削油のミストを噴流す

に高速の気流が生じ、切屑は、この気流にのつ
て、切削面に当ることのないように排出される。 In ultra-precision turning, chips are usually discharged by placing a suction port of a vacuum suction machine near the cutting point and sucking up the chips. If necessary, a jet of air or a mist of cutting oil may be directed toward the cutting point. These settings create a high-speed airflow near the cutting point, and the chips are discharged along with this airflow without hitting the cutting surface.

屑が連続的でない場合や、連続的であつても細い
場合には大変困難になる。[Problems to be Solved by the Invention] In this conventional chip evacuation method, air vortices 22 and stagnation are generated around the tool 21 as shown in FIG.
This results in damage to the cutting surface because it is not discharged quickly. To avoid this situation, adjust the size, shape, position, angle, etc. of the suction port and the strength of suction. However, this adjustment is very delicate and becomes particularly difficult when the chips are not continuous or are continuous but thin.
このようなことから、切屑の排出が容易かつ確
実で、切屑が切削面に当ることのない切屑の処理
技術の開発が望まれている。 For this reason, it is desired to develop a chip disposal technique that allows easy and reliable removal of chips and prevents the chips from hitting the cutting surface.

The purpose of this invention is to provide a cutting tool that can

連続性は刃先チツプ１２の箇所で中断している。 The rectifying guide 8 is attached to the shank 11 and protrudes like wings on both sides of the cutting edge tip, but it is particularly important that the surface of the rectifying guide 8 that faces the workpiece 2 forms the airflow rectifying surface 13. ,
This airflow regulating surface 13 is preferably streamlined, but since the cutting edge tip 12 protrudes from the approximate center of this airflow regulating surface 13, the integral continuity of this airflow regulating surface is interrupted at the cutting edge tip 12. ing.
