What was 00 m / min is 4000-5000 m /
High speed cutting of min is required. Since it is necessary to reduce the weight of the tool body as a condition for high speed rotation with a milling cutter, the material of the tool body is changed to aluminum alloy to reduce the weight, and sufficient measures to prevent the cutting tool from popping out due to centrifugal force are taken. Need to be implemented. Since aluminum alloy is used for the material of the tool body, fixing the cutting tool with wedges leads to insufficient rigidity of the cutting tool storage groove, so the same clamping means as the conventional one cannot be followed.

The present invention is
An object is to provide a rotary cutting tool that solves these problems.

A single V notch 6 is provided. Further, the cutting tool 3 is fixed to the tool body 1 side with a fixing screw 7. 8 is a chip pocket. Since the material of the tool body 1 is made of aluminum alloy and its rigidity is reduced, it is necessary to use a wedge to prevent the blade 3 from popping out due to centrifugal force.
Since there is a risk of opening, the tip is fixed by the clamp screw 9 that abuts on the V notch 6.

0 is provided, and is in contact with a flat head screw 12 screwed to the tool body 1 at an opposing position. Since the hole through which the fixing screw 7 for fixing the cutting tool 3 penetrates is formed as a slightly long hole,
The hook hole 11 penetrating the head of the adjuster 10 can be used to rotate the adjuster 10 to finely adjust the entire cutting tool in the front cutting edge direction. Further, if the cutting blade 4 is a throw-away tip, the cutting tool 3 becomes a cartridge type and the unit of the cutting tool 3 can be replaced, and economical cutting tool management can be performed. Reference numeral 13 is a fitting groove with which the rotary shaft of the milling machine body is fitted.

It has already been explained that the blade 3 is inserted into the. Cutting edge 4
Since PCD and CBN which are the cutting edges 4a are expensive sintered bodies, as shown in FIG.
Are joined together. And the cutting edge 4 is the shank 5
Is brazed to form the cutting tool 3.

Required. In order to meet these requirements, PCD obtained by sintering fine diamond particles containing a metal binder under high temperature and high pressure is suitable for processing an aluminum alloy. Furthermore, PCD obtained by sintering slightly coarse diamond particles under high temperature and high pressure is suitable for processing cemented carbide. Further, CBN sintered at high temperature and high pressure using a catalyst such as magnesium boron nitride made from cubic boron nitride as a raw material has low reactivity with an iron-based metal, and is therefore suitable for processing hardened steel.

る。Since an aluminum alloy is used as the material of the tool body 1, fixing the cutting tool 3 with a wedge as in the prior art leads to insufficient rigidity of the tool body 1, and as shown in FIGS. By bringing the tip of the clamp screw 9 into contact with the V notch 6 provided on the gold 4b, the blade 3 is fixed so as not to pop out due to centrifugal force. Therefore, in order to insert the cutting tool 3 into the tool storage groove 2 smoothly, L 2 is 0.0
A gap of 3 to 0.05 mm is required. That is, in order to prevent chips from entering the gap, the level difference L 1 between the rake face of the cutting blade 4 and the upper face of the shank 5 needs to be 0.06 to 0.8 mm.

４の欠損を招くことになる。FIG. 4B shows the state of the chips 17 when processed at high speed. When the work material is an aluminum alloy and is subjected to high-speed cutting, the chips 17 linearly collide with the chip pockets 8 without any time margin for curling. Then, the tip of the chip 17 slides on the rake face of the cutting blade 4 and enters the gap L 2 between the tool storage groove 2 and the shank 5. When the chips 17 are allowed to enter, the chips 17 remain as foreign matter.
The new chips 17 collide with each other one after another, the discharge of the chips 17 is hindered, the cutting resistance is extremely increased, and eventually the cutting tool 4 is damaged.

If the rake face of the cutting edge 4a is formed at a position L 1 higher than the upper surface of the shank, the chips 17 that collide linearly are prevented from entering the gap L 2 and are smoothly moved along the curved surface of the chip pocket 8. Is discharged.
That is, it is preferable to set the relationship between the gap and the step of the rake face to L 1 > L 2 . If the lower limit L 1 is 0.06 mm, the above relationship is satisfied, and if the upper limit L 1 is 0.8 mm, it is sufficient, and it is unnecessary to increase the amount of the expensive sintered body.
