- the body has a cutting edge, a rake face and a chip breaker.
- the cutting insert of Patent Document 1 forms a large negative land on the edge of the upper surface of the substrate including the ultra-high hardness sintered body, and is super high at a position where the negative land is left slightly along the ridgeline that becomes the cutting edge.
- a flat land that forms a rake face is formed in the ultra-high hardness sintered body by removing the corner portion of the sintered hard body, and the end of the land is obliquely rounded up to form a chip breaker.
- the chip breaker is composed of a protrusion protruding from the negative land position toward the tip of the arc blade so that the center is large and a breaker wall obliquely rising from the rake face toward the upper side of the protrusion.
- the breaker wall is composed of two surfaces connected at an angle.
- Patent Document 1 has a rake angle set to 0 °. Therefore, the cutting resistance is large, crater wear occurs, and there is a room for improving the life by reducing the cutting resistance.

Therefore, it has been conventionally performed to bond a diamond sintered body to the corner portion of the base material to form a cutting edge, a rake face and a chip breaker on the diamond sintered body, and to give a positive rake angle to the rake face. ing.
- a cutting insert with a cutting edge made of a super-hard sintered body is used for machining difficult-to-cut materials such as hardened steel and is required to withstand a large cutting load.
- a positive rake angle is given, the strength of the cutting edge is lowered and a product that can withstand practical use cannot be obtained. For this reason, there is no product on the market that has a cutting edge formed of an ultra-high hardness sintered body and has a positive rake angle.
- the object of the present invention is to realize a reduction in cutting resistance, an improvement in life, and an improvement in chip disposal performance by making it possible to impart a positive rake angle to the cutting insert while ensuring the necessary strength of the cutting edge.

- a cutting blade having an arcuate blade with a chamfered portion for reinforcing the cutting edge was formed on the ultra-high hardness sintered body.
- substantially constant does not mean that there is no height difference at all, but means that there is no large height difference in the portion where the cutting edge is formed. For example, if the height difference of the portion constituting the arc blade is within 0.5 mm, it can be regarded as almost constant.
- the chamfered portion may be a chamfer surface (C surface) or a rounded surface subjected to honing.
- a positive rake angle is imparted to the rake face, and the ridge line formed by the intersection of the rake face and the side face of the ultra-high hardness sintered body approaches the lower surface of the substrate as the distance from the cutting edge increases. Tilted in the direction.

- the ultra-high hardness sintered body 3 is a well-known sintered body containing 20% by volume or more of cubic boron nitride.
- a base 4 having a predetermined amount of depression from the upper surface is formed at the acute corner portion of the base 2, and the ultra-high hardness sintered body 3 is brazed and joined to the base 4. And the rake face 6 and the chip breaker 7 which fell from the upper surface of the cutting edge 5 and the ultra-high hardness sintered body 3 are formed in the ultra-high hardness sintered body 3.
- the cutting edge 5 has an arcuate blade 5 a having a substantially constant height on the ultra-high hardness sintered body 3.
- the illustrated cutting edge 5 includes a circular arc blade 5a having a 1 ⁇ 4 circle in a plan view shown in FIG. 3 and a straight blade 5b having a short length connected to both ends of the circular arc blade, but the straight blade 5b is omitted. It can happen.
- the cutting edge 5 is formed with a chamfered portion 8 for reinforcing the blade edge that forms an obtuse angle with respect to the side surface of the ultra-high hardness sintered body 3. Further, the rake face 6 is given a positive rake angle ⁇ 1 shown in FIG.
- the illustrated chamfered portion 8 is a negative land formed by a flat surface, but may be a round honing surface.
- the chamfer width s shown in FIG. 6 of the chamfered portion 8 seems to be about 0.01 to 0.15 mm. This is a value smaller than the cutting width under general cutting conditions, and it is possible to achieve both strengthening of the cutting edge and ensuring of sharpness. Further, if the chamfer width s is smaller than the cut width, the chips flow along the rake face, so that the chips can be treated well.
- the chip breaker 7 has a protrusion 7a protruding from the line L2 intersecting the bisector L1 of the corner angle in the plan view of the chip in the direction of the tip T of the arcuate blade 5a, and the protrusion 7a.
- the tip T of the arcuate blade 5a is located on the bisector L1 of the corner angle as shown in FIG.

- the rake angle ⁇ 1 is preferably greater than 0 ° and not greater than 30 °
- the rising angle ⁇ 2 of the first and second breaker walls 7b and 7c is not less than 30 °. 80 ° or less is appropriate.
- This core-lowering cutting insert may have a so-called No. 2 hit in the inner diameter processing and increase the turning resistance.
- the cutting insert according to the present invention can be set so that the amount of core down is 0 or the center of the blade is raised above the upper surface of the substrate by giving a positive rake angle to the cutting edge. Thereby, the second hit in the inner diameter machining can be avoided, and the degree of freedom in selecting the machining conditions is increased.
- the width w1 of the rake face 6 at the center of the arc blade and the width w2 at the position along the side surface of the ultra-high hardness sintered body 3 (the rake face having the width of w2 is not necessary in the region not corresponding to the cutting edge) In either case, it is appropriate that the thickness is about 0.1 to 0.5 mm.
- the rake face 6 may be designed to become wider as it goes away from the center of the nose so that the condition of w2> w1 is satisfied. This design is effective in further reducing the outflow resistance of the chip because the contact pressure of the chip with respect to the first breaker wall 7b becomes small.
- the rake face 6 need not be provided in a region far from the center of the nose and where no cutting edge is formed.
- a negative land (chamfered portion) 9 having a predetermined height is formed at the intersection of the upper surface 2a and the side surface 2b of the substrate 2, and the upper side e1 of the protrusion 7a is interposed between the negative land 9 and the upper surface 2a. It arrange

- a cutting test was performed under the cutting conditions different from those in Example 1 using the same tool as in Example 1. And the cutting resistance (main component force, back component force, feed component force) of those tools and the chip disposal performance of each tool were investigated. The results are shown in FIG. 9 and FIG.
- the cutting conditions were set to f: 0.3 mm / rev by changing only the feeding of the processing conditions from that of Example 1, and all other conditions were the same as those of Example 1.
