から行われている。[Prior Art] Conventionally, a lathe device as shown in FIG. 5 has been common, in which one end of a workpiece 3 is gripped on a bed 2 having legs 1 on the left and right sides as shown by chain lines. The grip part 4 that fixes the
a main spindle 4, a main spindle 5 having a built-in rotary drive means for giving high-speed rotation to the main spindle 4, and a tailstock 6 disposed opposite to the main spindle 5 and supporting the other end of the workpiece 3. are assembled. Then, the headstock 5 and the tailstock 6 are
In between, move the top of the bed 2 in the left and right direction (so-called vertical direction).
A carriage 7 is attached to move the carriage, and on top of it,
A transverse feed table 8 that moves in the front-rear direction (so-called lateral direction) is attached. Furthermore, on this horizontal feed table 8,
A tool post 10 is attached via a tool feed post 9, and a cutting tool 11 (so-called bite) is fixed to this part with a screw, as shown in Fig. 6 (A-A' cross section in Fig. 5). be done. Further, 12 (returning to Fig. 5) is a water injection nozzle, which extends from the cutting tool feeder 9 and injects cutting fluid at low pressure (0,1 to 1
kg/cfl) can be applied toward the cutting part. In addition, if the above cutting fluid is applied,
Generally, as shown in FIG. 7, the direction in which the cutting blades 1, 1a enter the workpiece 3, and the direction in which they aim at the gap between the cutting blade 11a and the generated chips 3a (arrow A), It is carried out from any direction perpendicular to the direction of the arrow (arrow B).
したがって、この装置によれば、主軸台５と心押し台６
との間に支持される工作物３の外周面に、切削工具１１

作物３に高速回転を与えることによって旋削を行うこと
ができる。Therefore, according to this device, the headstock 5 and the tailstock 6
A cutting tool 11 is attached to the outer peripheral surface of the workpiece 3 supported between the
Turning can be performed by pressing the cutting edge of the workpiece 3 and applying cutting fluid from an appropriate direction while rotating the workpiece 3 at high speed.

できなくなる、等の問題が生じることがわかった。However, when cutting using the above lathe device, the faster the cutting speed, the harder the workpiece surface becomes as if it had been quenched due to the cutting heat when cutting carbon steel such as 345C. ■As chips with cutting heat cover the surface of the workpiece, the workpiece itself gets heated and expands.
If you cut in this condition, the machining dimensions will be distorted, and the surface of the workpiece will melt due to cutting heat, and the molten metal will adhere to the cutting edge of the cutting tool, forming a so-called "built-up edge" and making cutting impossible. It was found that this occurs.
このため、従来の旋盤装置では、高速切削を行うことは
難しいのが実情で、その解決が望まれていた。For this reason, it is difficult to perform high-speed cutting with conventional lathe devices, and a solution to this problem has been desired.

ことができる。[Operation] That is, the inventor conducted a series of studies on a lathe device that can suppress heat generation at the cutting point and heat generation of chips to a low level. As a result, the cutting fluid, which was conventionally used at low pressure mainly to provide lubrication to the cutting point and remove chips, can now be applied at high pressure, and moreover, from the side opposite to the side where the cutting tool's cutting edge enters the workpiece. The inventors have discovered that when the fluid is discharged toward the cutting point, the cutting point is instantly cooled by the high-pressure cutting fluid, resulting in almost no thermal effect on the workpiece or the inside of the cutting blade, and has thus arrived at this invention. Therefore, according to this invention, even if the cutting blade is kept in a low temperature state and the cutting speed is increased, excellent cutting can be performed as if low temperature cutting was being performed.

It is the same as that, and the overall diagram is omitted. In this device, 15.15' extends from the blade feeder 6. Cutting fluid is 10-200kg/cT with the second high-pressure water nozzle.
It is designed to be discharged at a high pressure of 1 liter. In addition, in this device, as the cutting tool 11, a implanted type tool consisting of a cutting blade tip lla and a tool holder 11b as shown in FIG. 2 is used.
5 sets the cutting point to the cutting blade tip 11. A. High pressure water is discharged from the side where chips are generated for cooling. This first high-pressure water nozzle 15 has the effect of repelling the generated chips and, at the same time, instantaneously cools the part of the workpiece 3 into which the cutting edge of the cutting blade depth lla is about to enter, reducing the temperature to a low temperature. In order to maintain the condition, the workpiece 3
There is almost no heat shadow on the cutting blade tip lla, and the state is as if low-temperature cutting was being performed. Therefore, even if the workpiece 3 is made of carbon steel such as 345C, it will not become as hard as if it had been quenched, and
There is no possibility that the surface of the workpiece 3 will melt due to cutting heat and a "built-up cutting edge" will be formed. Further, the workpiece 3 itself will not expand thermally and the machining dimensions will not be distorted. Furthermore, the so-called "No. 2" cutting edge (the blade that collides with the surface of the workpiece 3 and bites into it is the "No. 1"), which was easily damaged in the past, and the "No. 2" forms a cutting edge angle with this No. 1 blade. There will be no damage to the other side (the side on the other side).

る。On the other hand, a second high-pressure water nozzle 15' provided together with the first high-pressure water nozzle 15 is connected to the cutting point and the cutting tool 1.
This is used to cool the first cutting tip at the same time, and reinforces the cooling effect of the first high-pressure water nozzle 15.

できる。The cutting blade depth 11a of the cutting tool 11 may be made of any material, but for example, it may be made of ultrafine cemented carbide made of sintered tungsten carbide particles and cobalt particles (with an average particle diameter of 0.3 to 1.0μ, the blending ratio of tungsten carbide particles and cobalt particles is 85 to 90% by weight of tungsten carbide, and 15 to 10% of cobalt.
% by weight) is preferably used. In other words, while the ultrafine grain cemented carbide has the advantages of being hard and having high toughness, it is weak against heat and could only be used at low temperatures (low speed cutting). 1
．． When cutting is performed while discharging high-pressure water from the second high-pressure water nozzle 15, 15', as described above, the cooling effect of the high-pressure cutting fluid discharged from the first high-regia nozzle 15 causes a Since low-temperature cutting is performed, good cutting can be maintained over a long period of time without damaging the cutting edge of the cutting blade tip lla even if cutting is performed at high speed.

However, if provided, it may be extended from the tool feed stand 9 or, as shown in FIG. It may also be discharged. Alternatively, as shown in FIG. 4, a water supply channel 20 may be formed in the tool rest 10 and the water may be discharged from the end face of the tool rest 10.

This allows the cutting edge of the cutting blade to instantly cool the part of the workpiece that it is about to enter. For this reason,
Almost no heat generated at and around the cutting point is transmitted to the inside of the workpiece or cutting tool, so neither the workpiece nor the cutting blade suffers thermal damage, even when cutting is performed at high speed.
Good cutting can be performed as if it were low-temperature cutting. Therefore, when using a hard workpiece,
Even when using a special cemented carbide tool that is sensitive to heat, it has the advantage of being able to perform good cutting over a long period of time without reducing machining speed.
