Description of the Related Art As throw-away type rotary cutting tools which mainly perform peripheral cutting, there are, for example, a corner cutting cutter shown in FIG. 6 and an end mill shown in FIG. These tools are configured by attaching a throw-away tip 21 having a substantially square shape, a diamond shape, a parallelogram shape, or the like to the main body 1. In addition,
In the illustrated tool, the outer peripheral blade 22 is parallel to the tool axis C, and the depth of cut is determined within the effective length range of the outer peripheral blade.

【発明が解決しようとする課題】上述した従来のカッタ
は、最大切込みがチップサイズによって決まる。従っ
て、切込みを大きくしよとすれば、チップサイズを大き
くしなければならない。In the above-mentioned conventional cutter, the maximum depth of cut is determined by the chip size. Therefore, if it is desired to increase the depth of cut, the chip size must be increased.
【０００４】また、切込みが大きくなると、ワークに対
する切刃の接触長さが長くなるので、切削抵抗、喰い付
き時の衝撃が大きくなっていわゆるビビリが生じやすく
なり、切屑も幅広いものになって排出性が悪くなる。Further, as the depth of cut increases, the contact length of the cutting edge with the work becomes longer, so that the cutting resistance and the impact at the time of biting increase, so-called chattering easily occurs, and the chips also become wide and discharged. The sex becomes worse.

The first blade and the second cutting edge are alternately provided in the circumferential direction so as to be mounted so that the cutting edge ridge continuing to the other side of the nose portion becomes a part of the outer peripheral blade. It is a thing.

減できる。In the throw-away tip of the present invention, the position of the nose is increased and the cutting edge from the nose portion to the adjacent corner portion has a rake angle of α, and moreover, it is inclined downward along the cutting edge. Since the breaker is provided, it is possible to use the tool with the rake angle in the tool axial direction and the rake angle in the radial direction both being positive, which improves the sharpness and reduces the cutting resistance.
【００１０】また、切刃を円弧にしたものは切刃が滑ら
かにワークに喰い付くため、衝撃緩和の効果も生じる。Further, in the case where the cutting edge is arcuate, the cutting edge smoothly bites the work, so that the effect of mitigating impact is also produced.

In this tip 1, a rounded nose portion 3 is formed at a diagonal corner (β ≦ 90 ° corner) of the flat plate-shaped main body 2 having a longer diagonal line. As shown in FIG. 1 (c), the nose portion 3 rises upward, and therefore the nose portion 3

Although it is inclined at the angle (see (d)), θ may be 0 °. Reference numeral 8 denotes a mounting hole opened at the center of the chip body 2.

0 is the throw-away tip 1 of FIG.
The first blade 13 and the second blade 14 are attached to the seat groove 12 provided on the outer periphery of the distal end of the first blade so that they are alternately present in the circumferential direction.

The throw-away tip 1 has a cutting edge 4 in which one nose portion 3 is located on the outer periphery of the tip of the cutter and which is continuous to one side of the nose portion.
Is mounted in a direction parallel to the tool axis C at the outermost periphery.

して工具軸方向につながる。As shown in FIG. 5 (b), the second blade 14 has a throw-away tip 1 in which one nose portion 3 is located on the outer periphery of the rear side of the cutter and is connected to the other side of the nose portion. 4 is mounted on the outermost peripheral portion in a direction parallel to the tool axis C. The tip 1 forming the second blade 14 is in a posture in which the tip 1 for the first blade of FIG. 5A is rotated by β ° in the clockwise direction and (180−β) ° in the counterclockwise direction. The first half of the outer peripheral edge of the cutter is on the tip side.
The blade 13 and the other half are constituted by the second blade 14, respectively, and the trajectories of the two blades partially overlap and are connected in the tool axial direction.

第２刃１４の有効長さを加算した長さが外周刃の実質長
さとなるので、従来のカッタに比べると２倍の長さ範囲
で切込みを設定することができる。This can be considered as a state in which the outer peripheral blade of the cutter is divided and arranged in steps, and the effective length of the first blade 13 and the effective length of the second blade 14 are added together to obtain the substantial length of the outer peripheral blade. Therefore, the incision can be set in a length range twice as long as that of the conventional cutter.
【００２１】また、切刃の分割配置により、１刃当たり

て排出が容易になる。Further, the divided arrangement of the cutting blades reduces the cutting load per blade and the chips are also divided into two parts to facilitate the discharge.

い。The outer peripheral blade formed by the first blade 13 and the second blade 14 has a positive rake angle α in the axial direction of the tool, and the inclination of the breaker surface 6 also causes the peripheral edge in the radial direction of the tool. With a positive rake angle, both blades have good sharpness.

引き上げ力も小さくなってワークが動き難くなる。Furthermore, the direction in which the rake angle α is attached is the first blade 1
3 and the second blade 14 are opposite to each other, and the thrust forces acting on these blades cancel each other out, so that the pulling force acting on the work becomes small and the work becomes difficult to move.
【００２４】図中１５は、チップ固定用のクランプねじ

ことも可能である。The tool to be applied may be an end mill or a side milling cutter. In addition, it is also possible to arrange two or more first blades 13 and two second blades 14 at the same ratio in the tool axial direction to divide the outer peripheral blade into an even number of 4 or more.

の要求がある用途に利用すると特に効果的である。As described above, the throw-away insert of the present invention can be used with the rake angle in the tool axial direction and the rake angle in the radial direction both being positive, and the sharpness is improved. Also, by making the cutting edge curved, it is possible to reduce the impact when biting. Therefore, it is particularly effective when used in applications where reduction of cutting resistance and impact relaxation are required to prevent chattering.

り、加工の安定化や加工精度向上面でも有利になる。Further, in the rotary cutting tool according to the present invention, since the substantial length of the outer peripheral blade is an even multiple of the tip cutting edge length, the cutting depth can be set large without increasing the chip size. Further, in addition to good cutting quality, the load per blade is reduced, and the chips are also divided and discharged, so that comfortable cutting can be performed comfortably even in heavy cutting with a large cutting depth. Further, since the thrust forces generated in the first blade and the second blade cancel each other out and become small, the stability of the stationary work is enhanced, which is advantageous in terms of stabilization of processing and improvement of processing accuracy.
