Definitions
- the present invention relates to a cutting tool.
- a technique for improving wear resistance by focusing on the surface properties of the material rather than the material of the hard coating has also been proposed.
- a technique for example, in Patent Document 1 by smoothing the arithmetic average roughness Ra of the hard coating surface to 0.05 ⁇ m or less, surface defects are reduced, and anti-galling and oxidation resistance are improved.
- Techniques for improving wear resistance have been proposed. These techniques are also expected to improve wear resistance due to surface properties in the field of cutting tools. However, the actual situation is that the effect of improving the wear resistance is not sufficient only by controlling the arithmetic average roughness Ra to 0.05 ⁇ m or less.
- the present invention has been made in view of the circumstances as described above, and its purpose is to devise the surface properties of the hard coating to further improve the wear resistance, and to convert a high-hardness member such as cast iron into a work material. Even in such a case, it is an object of the present invention to provide a cutting tool useful for high-speed cutting.
- the cutting tool of the present invention capable of solving the above problems is a cutting tool in which a hard coating is coated on the surface of a substrate, and the root mean square slope R ⁇ q on the surface of the hard coating is 0.060 ° or less. It is characterized by that.
- the arithmetic mean roughness Ra on the surface of the hard coating is preferably 0.030 ⁇ m or more and 0.30 ⁇ m or less. It is also preferable that the maximum height roughness Rz on the surface of the hard coating is 0.20 ⁇ m or more and 3.5 ⁇ m or less.
- Examples of the base material used in the cutting tool of the present invention include tungsten carbide base cemented carbide, cermet alloy, high speed tool steel, and alloy tool steel. Moreover, as a hard film
- a cutting tool with further improved wear resistance can be realized by setting the root mean square slope R ⁇ q on the surface of the hard coating to 0.060 ° or less.
- the present inventors examined the relationship between the shape of the hard coating surface and the wear resistance. Until now, it has been considered that the influence of the surface properties of the hard coating on the wear resistance is caused by a large parameter in the height direction (for example, the above-mentioned arithmetic average roughness Ra). However, according to the study by the present inventors, it has been clarified that the inclination of the protrusion existing on the surface of the hard film has a larger influence on the wear resistance than the parameter in the height direction. .
- the cutting tool of the present invention is characterized in that the root mean square slope R ⁇ q on the surface of the hard coating is 0.060 ° or less.
- This root mean square slope R ⁇ q defines the slope of the protrusion in the roughness curve (contour curve) of the hard coating surface, as described in JIS B0601 (2013).
- the root mean square slope R ⁇ q When the value of the root mean square slope R ⁇ q is increased, the frictional force generated in the direction parallel to the surface is increased, and adhesion is likely to occur, so that the coating is easily broken.
- the root mean square slope R ⁇ q In order to exert the above effect, the root mean square slope R ⁇ q needs to be 0.060 ° or less.
- This root mean square slope R ⁇ q is preferably 0.020 ° or less, and more preferably 0.010 ° or less.
- the lower limit of the root mean square slope R ⁇ q is about 0.001 ° or more considering manufacturability and the like.
- the definition and measurement method of the root mean square slope R ⁇ q is based on JIS B 0601 (2013).
- the arithmetic average roughness Ra on the surface of the hard coating is preferably 0.30 ⁇ m or less, and more preferably 0.25 ⁇ m or less.
- the arithmetic average roughness Ra on the surface of the hard coating becomes too small, the contact area with the work material increases, so that friction during cutting increases and wear tends to proceed.
- the arithmetic average roughness Ra is preferably 0.030 ⁇ m or more, and more preferably 0.050 ⁇ m or more.
- the definition and measurement method of arithmetic average roughness Ra is based on JISJB0601 (2013).
- Controlling the maximum height roughness Rz (JIS B 0601 (2013)) on the surface (contour curve) of the hard coating also suppresses the amount of tool wear from the same viewpoint as adjusting the arithmetic average roughness Ra. It is effective in doing.
- the maximum height roughness Rz is preferably 3.5 ⁇ m or less, more preferably 2.0 ⁇ m or less.
- the maximum height roughness Rz on the surface of the hard coating is preferably 0.20 ⁇ m or more, and more preferably 0.50 ⁇ m or more.
- the definition and measurement method of the maximum height roughness Rz are based on JIS B 0601 (2013).
- Examples of the base material for forming the hard coating include WC—Co alloys, WC—TiC—Co alloys, WC—TiC—TaC (NbC) —Co alloys, WC—TaC (NbC) —Co alloys, and the like.
- alloy tool steels such as SKS11 and SKD1 defined in JIS G4404 (2006).
- the kind of the hard film used in the present invention is not particularly limited, and may be a conventionally known hard film. In short, the surface properties only need to satisfy the above-described requirements.
- a film made of nitride, carbonitride, or oxide containing at least one element of Ti, Cr, and Al can be mentioned.
- AlTiN, TiCrAlN, TiCrAlCN, TiCrAlO, AlCrN, Al 2 O 3 and the like are effective as a hard film excellent in wear resistance and high temperature lubrication resistance.
- the hard film may be formed as a single layer, but if necessary, either a film in which two or more films having the same constituent elements and different compositions are laminated or a film in which two or more films having different constituent elements are laminated is used. There may be.
- the thickness of the hard coating (total thickness in the case of the laminated coating) varies depending on the application, but is preferably about 0.5 ⁇ m or more and 20 ⁇ m or less. If this thickness (film thickness) is less than 0.5 ⁇ m, it is too thin and excellent wear resistance is not sufficiently exhibited. On the other hand, if the film thickness exceeds 20 ⁇ m, the film is likely to be chipped or peeled off during cutting.
- the film thickness is more preferably 1 ⁇ m or more, and further preferably 2 ⁇ m or more.
- the upper limit with a more preferable film thickness is 15 micrometers or less, More preferably, it is 10 micrometers or less.
- the hard coating can be coated on the surface of the substrate using a known method such as physical vapor deposition (PVD method: Physical vapor deposition process) or chemical vapor deposition (CVD method: Chemical vapor deposition process).
- PVD method Physical vapor deposition process
- CVD method Chemical vapor deposition process
- a target used as a solid evaporation source is evaporated or ionized, and a film is formed on a target object (base material) in a gas containing nitrogen, hydrocarbon, or oxygen.
- arc ion plating A reactive PVD method such as an ion plating method such as an Arc-Ion-plating method or a sputtering method is effective.
- Preferred conditions for film formation by the arc ion plating method include the following conditions, for example.
- Total pressure 0.5 Pa to 4 Pa
- Applied current discharge current: 100 to 200
- Substrate temperature during film formation 300 ° C. or higher and 800 ° C. or lower
- the hard coating surface formed above, or the base material surface before forming the hard coating is projected using a projection type polishing apparatus. Polishing may be performed while adjusting the time, the projection direction of the projection material, and the like. For example, if the projection pressure is increased while adjusting the projection direction of the projection material or the projection time is lengthened, the root mean square slope R ⁇ q can be reduced.
- the surface of the hard film formed as described above is projected-type polished as in the case of adjusting the root mean square slope R ⁇ q. What is necessary is just to adjust a projection pressure, a projection time, the projection direction of a projection material, etc. using an apparatus.
- the surface roughness can also be adjusted by adjusting the particle size of the projection material. For example, when the particle size of the projection material is large, the arithmetic average roughness Ra and the maximum height roughness Rz tend to increase.
- the cutting tool of the present invention exhibits excellent wear resistance and is particularly useful as a cutting tool for high-speed turning in a wet environment.
- a film having the composition and structure shown in Table 1 below was formed by an AIP apparatus having a plurality of evaporation sources.
- SNGA120408 and SNMA120408 two types of cutting inserts (manufactured by Mitsubishi Materials Corp., cemented carbide cutting tips) and mirror-finished cemented carbide specimens for surface roughness investigation (13 mm ⁇ 13 mm) ⁇ 5 mm thickness) was used.
- These substrates were ultrasonically degreased and washed in ethanol and introduced into an AIP apparatus. After exhausting the pressure in the apparatus to 5 ⁇ 10 ⁇ 3 Pa, the substrate was heated to 500 ° C., and etching with Ar ions was performed for 5 minutes. Thereafter, nitrogen gas or oxygen gas is introduced up to 4 Pa, an arc evaporation source (target diameter: 100 mm) is operated at a discharge current of 150 A, an AlTiN film, an AlTiN (base material side) + TiCrAlN (surface side) laminated film, and TiCrAlO Films were formed on the base material with a thickness of about 10 ⁇ m to form cutting tools.

- a projection type polishing apparatus was used to adjust the surface pressure by adjusting the projection pressure, the projection time, the particle size of the projection material, the projection direction, and the like.
- the surface parameter was measured using a stylus type surface roughness meter (DekTak6M), and a cemented carbide specimen for surface roughness investigation was used. Performed. In this measurement, the scanning length is 1 mm, the number of measurement points in the horizontal direction is 3, and the root mean square slope from the roughness curve obtained by removing the waviness component from the measured surface curve in accordance with JIS B 0601 (2013). R ⁇ q, arithmetic average roughness Ra, and maximum height roughness Rz were calculated. This was measured at three arbitrary points on the surface, and the average value was adopted.
- the wear resistance was evaluated by measuring the flank wear width by conducting a cutting test under the following conditions using the samples (test Nos. 1 to 12) formed on the cemented carbide cutting tip. .

- Test No. No. 7 shows that the root mean square slope R ⁇ q is within the range specified by the present invention, so that the wear resistance is good (the flank wear width is 300 ⁇ m), but the arithmetic average roughness Ra and the maximum height roughness. In this example, Rz is larger than the preferred upper limit.
