Definitions
- the present invention relates to a cutting insert that exhibits excellent performance in terms of chip disposal and life in rough machining of difficult-to-cut materials such as titanium, titanium alloys, and Ni alloys.
- a cutting insert as disclosed in Patent Document 1 below or a cutting insert as disclosed in Patent Document 2 below is employed.
- the cutting insert of Patent Document 1 forms a flat land for reinforcing the cutting edge having a width of about 0.15 to 0.25 mm on the rake face along the cutting edge. Further, a breaker groove is provided following the land, and a breaker protrusion is disposed between the breaker groove and the central land portion of the cutting insert.
- the cutting insert of Patent Document 2 is provided with a breaker groove on a rake face that intersects the flank at an acute angle, and a breaker protrusion is disposed between the breaker groove and the central land portion of the cutting insert.
- a rake face with a rake angle of less than 20 ° and a large installation width of about 0.5 mm along the cutting edge is used for machining stainless steel.
- a breaker groove having an inclination angle exceeding 20 ° is also provided at the end of the rake face (the side away from the cutting edge is considered as the end).
- the structure as in Patent Document 2 without a land has a good sharpness, and the chip disposal performance is superior to that with a land.
- the thickness of the blade edge portion is small, there is a problem that when the crater wear progresses, the blade edge is liable to be lost and the life is shortened.
- the object of the present invention is to devise the shape of the cutting insert so that the crater wear is suppressed even when processing difficult-to-cut materials, the life is extended, and at the same time, good chip disposal is exhibited.
- a cutting insert having a cutting edge in the corner R portion is configured as follows. That is, a land that crosses the flank and generates the cutting edge, and a breaker groove that follows the land are provided on the rake face, Has a breaker on the central land side of the breaker groove, The width T of the land formed on the cutting edge of the corner R portion is set to 0.05 mm ⁇ T ⁇ 0.15 mm, On the slope of the land side of the breaker groove that is descending toward the direction away from the cutting edge, a mountain portion along the entire area of the cutting edge of the corner R portion is formed in the depth direction of the breaker groove (direction toward the groove bottom) ) Are arranged in a row, The rake angle ⁇ of at least one inclined surface among the inclined surfaces forming each peak is set to satisfy the condition of ⁇ > 20 °.

- the land width T is 0.07 mm ⁇ T ⁇ 0.15 mm.
- the cutting insert of the present invention is provided with lands along the cutting edge, the thickness of the cutting edge is increased and the cutting edge is strengthened. However, the advancement of crater wear cannot be effectively prevented by only strengthening the blade edge with the land.
- the land width T is made smaller than 0.15 mm so that the sharpness is not impaired and the chips are divided, so that the reinforcing effect of the cutting edge by the land is limited.
- the lack of reinforcement of the cutting edge by the land is compensated by the mountain portion provided on the land-side slope of the breaker groove. That is, by providing a plurality of ridges, the thickness in the vicinity of the blade edge is increased and the blade edge strength is increased as compared with a structure without a ridge portion. Also, by arranging multiple peaks in the depth direction of the breaker groove, chip contact with the rake face (the groove surface of the breaker groove) may be localized, or the contact pressure may increase or decrease. It works effectively. These synergistic effects suppress crater wear.
- FIG. 3 is an enlarged sectional view of a position along line XX in FIG. 2.

- the illustrated cutting insert 1 is provided with cutting edges 4 over the entire periphery of the upper surface and the lower surface, and lands 9 and breaker grooves 10 are also formed along the entire area of the cutting edges.
- the breaker 11 rises diagonally from the back of the breaker protrusion 11a toward the central land portion 5 at the positions of the corner R portions 7 and 8 and a plurality of spherical breaker protrusions 11a arranged along the cutting edge 4.
- the breaker wall 11b formed higher than the breaker protrusion 11a is combined.
- the breaker wall 11b is protruded to the cutting edge side and is constituted only by the breaker wall 11b. Even if there is no breaker protrusion 11a, chips are processed, but the chip disposal performance can be improved by providing the breaker protrusion 11a.
- the mounting hole 6 is not essential.
- the land 9 and the breaker groove 10 are also provided in the corner R portion 8 on the obtuse corner side, but the land and breaker groove on the corner R portion on the obtuse corner side may be omitted. .
- the land 9 of the cutting insert shown in the figure is a plane perpendicular to the flank 3 (a plane having an inclination angle of 0 °), but even a land having a slight inclination angle (for example, 3 ° or less). Good.
- the width T of the land 9 formed on the cutting edge of the corner R portion is set to be larger than 0.05 mm and smaller than 0.15 mm. By ensuring the land width T of 0.05 mm or more, an effect that can be expected in terms of improving the strength of the blade edge portion can be obtained.
- the land width T formed on the cutting edge other than the corner R portion may be 0.15 mm or more.
- the width T of the land formed on the cutting edge of the corner R portion is smaller than 0.15 mm, the chip cutting function and the sharpness are prevented from being deteriorated due to the excessive land width. Can do.
- the width T of the land 9 is more preferably 0.07 mm ⁇ T ⁇ 0.15 mm. In this way, the chip cutting function and the sharpness can be reduced more effectively. In particular, when the cutting depth is large, it is more preferable to set the land width T to be larger (0.10 mm ⁇ T ⁇ 0.15 mm). *
- the breaker groove 10 is once lowered from the inner end of the land 9 and the end is warped.
- a plurality of ridges 12 as shown in FIG. 3 are arranged in the depth direction of the breaker groove 10 on the land-side (starting side) slope 10 a that has a downward slope toward the direction away from the cutting edge 4. It has been.
- the peak portion 12 extends at least to a corner R portion involved in cutting along the land 9 in a direction parallel to the cutting edge 4 and corresponds to the entire cutting edge of the corner R portion (participating in cutting). Provided to exist over the entire area of the cutting edge).
- the illustrated mountain portion 12 is created by intersecting two inclined surfaces A and B having different rake angles.
- the mountain portion 12 may have a shape in which a surface for removing a sharp ridgeline at the top of the mountain is disposed between the inclined surfaces A and B, but at least one inclined surface has a rake angle ⁇ of 20. Larger than °.
- the inclined surface B having a large rake angle functions as a substantial rake surface.
- a plurality of ridges 12 satisfying the two conditions of ⁇ A ⁇ B and WA ⁇ WB are arranged in the depth direction of the breaker groove 10 to increase the thickness in the vicinity of the blade edge.
- the land-side groove surface of the breaker groove 10 is inclined at the same angle as the inclined surface B with no peaks, the land-side groove surface is disposed at the position indicated by the line L in FIG. The portion above the line L when compared with that is the amount of increase in the insert material. This increase in insert material increases resistance to crater wear without impairing sharpness.
- the rake angles ⁇ A and ⁇ B of the inclined surfaces A and B are preferably set to ⁇ A ⁇ 20 ° and ⁇ B ⁇ 30 °. By carrying out like this, the better effect can be expected regarding the strength improvement while maintaining the sharpness.
- the upper limit is not particularly defined, but it is preferable to satisfy ⁇ ⁇ 60 ° in order to ensure a certain level of strength.
