Description

本発明は、基材の表面に金属層がコーティングされた切削用工具に係り、特に機械的性質の異なる２種類の金属層が交互に積層するようにコーティングされ、摩耗によって切削性能が変化しないように工夫された切削用工具に関するものである。   The present invention relates to a cutting tool in which a metal layer is coated on the surface of a substrate, and in particular, the coating is performed so that two types of metal layers having different mechanical properties are alternately stacked, so that cutting performance does not change due to wear. The present invention relates to a cutting tool that has been devised.

一般に、工作機械等に設けられる切削用工具には、切削時の摩擦に耐えるための硬さや、被削材を速やかに排出しうる摩擦係数の低さを示すすべり性等が求められる。従って、切削用工具には、求められる性能に応じて種々の工具用金属材料の中から適当な金属材料が基材として選択されるとともに、当該基材の表面には、特に必要な機械的性質を実現するために金属層がコーティングされることがある。   In general, a cutting tool provided in a machine tool or the like is required to have hardness to withstand friction during cutting, a slip property indicating a low coefficient of friction that can quickly discharge a work material, and the like. Therefore, an appropriate metal material is selected as a base material from various metal materials for tools according to the required performance, and the surface of the base material has particularly necessary mechanical properties. In some cases, a metal layer is coated to achieve the above.

下記特許文献１には、基材の表面にＴｉとＡｌの炭化物、窒化物及び炭窒化物のような耐摩耗性を有する金属を１層あたり１〜４μｍの厚さで１層乃至３層積層させて硬質被膜層を形成した金属部材についての発明が記載されている。   In the following Patent Document 1, a metal having wear resistance such as Ti and Al carbide, nitride and carbonitride is laminated on the surface of the base material in a thickness of 1 to 4 μm per layer. The invention about the metal member which made it form the hard film layer is described.

特開昭６２−５６５６５号公報JP-A 62-56565

上記特許文献に記載の発明によれば、基材の表面に耐摩耗性を有する金属を１層乃至３層積層させて硬質被膜層を形成したので、切削用工具に適用した場合には連続切削に対する耐摩耗性は向上するが、その他の性質、例えばすべり性等は十分とはいえず、切削時に削りくずを速やかに排出することができない。   According to the invention described in the above-mentioned patent document, a hard coating layer is formed by laminating one to three layers of metal having wear resistance on the surface of the base material. Therefore, when applied to a cutting tool, continuous cutting is performed. However, other properties such as slipperiness are not sufficient, and it is not possible to quickly discharge shavings during cutting.

本発明は、このような従来の問題点に鑑みてなされたものであり、切削時の摩擦に耐える硬度と、被削材を速やかに排出する高いすべり性を兼備し、しかも連続切削により摩耗しても性質が変化しない切削用工具を提供することを目的としている。   The present invention has been made in view of such conventional problems, and has both hardness to withstand friction during cutting and high slipperiness to quickly discharge the work material, and wears by continuous cutting. However, the object is to provide a cutting tool whose properties do not change.

本発明の実施形態を図１〜図７を参照して説明する。
１．アークイオンプレーティング装置の構造
本発明の切削用工具は、所定の表面粗さを有する基材の表面に、互いに機械的性質が異なるとともに、前記基材の表面粗さよりも小さい膜厚となるように、第１の金属層と第２の金属層を交互に積層したものである。基材の表面に２種類の金属層を交互に積層させるために、本例では図１に示すようなアークイオンプレーティング装置１が使用される。 An embodiment of the present invention will be described with reference to FIGS.
1. Structure of Arc Ion Plating Device The cutting tool of the present invention has different mechanical properties on the surface of a base material having a predetermined surface roughness, and has a film thickness smaller than the surface roughness of the base material. In addition, the first metal layer and the second metal layer are alternately laminated. In this example, an arc ion plating apparatus 1 as shown in FIG. 1 is used to alternately laminate two types of metal layers on the surface of the substrate.

図１に示すように、このアークイオンプレーティング装置１は、被コーティング物である切削用工具の基材を収納する真空チャンバー２を備えている。真空チャンバー２は高気密性の箱型容器であり、内部の気体を図示しない排気ポンプによって排気するための排気口３と、コーティング工程で内部に必要なプロセスガスを導入するための供給口４が設けられている。   As shown in FIG. 1, the arc ion plating apparatus 1 includes a vacuum chamber 2 that houses a base material of a cutting tool that is an object to be coated. The vacuum chamber 2 is a highly airtight box-type container, and has an exhaust port 3 for exhausting the internal gas by an exhaust pump (not shown), and a supply port 4 for introducing a process gas required in the coating process. Is provided.

真空チャンバー２内には、外部に設けられた図示しない駆動源によって回転する回転式テーブル５が設けられており、この回転式テーブル５にはバイアス電源６により一定の負のバイアス電圧が印加できるようになっている。   A rotary table 5 that is rotated by a drive source (not shown) provided outside is provided in the vacuum chamber 2, and a constant negative bias voltage can be applied to the rotary table 5 by a bias power source 6. It has become.

真空チャンバー２内には、切削用工具の基材にコーティングしようとする金属材料からなる第１及び第２のターゲット７，８が、回転式テーブル５の真上と左側方の２箇所にそれぞれ設けられている。これらのターゲット７，８は各アーク電源９の負極に接続されたカソードであり、各アーク電源９の陽極には各ターゲット７，８の周囲にそれぞれ設けられた略円筒形のアノード１０が接続されている。カソードである２つのターゲット７，８は、真空チャンバー２の外で回路的に接続されて同電位とされている。   In the vacuum chamber 2, first and second targets 7, 8 made of a metal material to be coated on the base material of the cutting tool are provided at two locations just above and on the left side of the rotary table 5. It has been. These targets 7 and 8 are cathodes connected to the negative electrode of each arc power source 9, and a substantially cylindrical anode 10 provided around each of the targets 7 and 8 is connected to the anode of each arc power source 9. ing. The two targets 7 and 8 that are cathodes are connected in a circuit outside the vacuum chamber 2 to be at the same potential.

２．アークイオンプレーティング装置１による金属層の形成
回転式テーブル５の上に切削用工具の基材１１を配置する。基材１１の材質としては、切削用工具としての用途・目的に応じて適宜選択すればよいが、例えば炭素工具鋼の他、炭素工具鋼に少量のタングステン、クロム、バナジウム等が添加された合金工具鋼（低合金工具鋼）や、鋼にクロム、タングステン、モリブデン、バナジウムといった金属成分を多量に添加した高速度工具鋼（ハイス鋼）を採用することができる。 2. Formation of Metal Layer by Arc Ion Plating Apparatus 1 A base material 11 for a cutting tool is disposed on a rotary table 5. The material of the base material 11 may be appropriately selected according to the use and purpose as a cutting tool. For example, in addition to carbon tool steel, an alloy in which a small amount of tungsten, chromium, vanadium or the like is added to carbon tool steel. Tool steel (low-alloy tool steel) and high-speed tool steel (high-speed steel) obtained by adding a large amount of metal components such as chromium, tungsten, molybdenum, and vanadium to steel can be used.

工具の種類により基材１１の表面粗さは異なるのが通常であるが、本例では、成膜前の基材１１の表面粗さとしては５００オングストロームから２０００オングストロームの範囲内を対象とした。図２に示す例では、表面粗さが２０００オングストロームとなっている。   The surface roughness of the base material 11 is usually different depending on the type of tool, but in this example, the surface roughness of the base material 11 before film formation is targeted within the range of 500 angstroms to 2000 angstroms. In the example shown in FIG. 2, the surface roughness is 2000 angstroms.

真空チャンバー２内の所定位置に金属材料からなる第１及び第２のターゲット７，８をそれぞれ装着してそれぞれアーク電源９に接続する。本例では、基材１１に２種類の金属層を交互に被着する。第１の金属層としては、基材１１及び第２の金属層に比べて相対的に硬度が大きい金属としてＴｉＡｌＮを採用するため、真空チャンバー２の上方に設ける第１のターゲット７はＴｉＡｌとする。また、第２の金属層としては、基材１１及び第１の金属層に比べて相対的にすべり性の高い金属としてＣｒＮを採用するため、真空チャンバー２の左側面に設ける第２のターゲット８はＣｒとする。各金属層に含まれるＮはプロセスガスである窒素ガスから供給される。   First and second targets 7 and 8 made of a metal material are mounted at predetermined positions in the vacuum chamber 2 and connected to an arc power source 9 respectively. In this example, two types of metal layers are alternately applied to the substrate 11. As the first metal layer, TiAlN is adopted as a metal having relatively higher hardness than the base material 11 and the second metal layer, and therefore the first target 7 provided above the vacuum chamber 2 is TiAl. . In addition, as the second metal layer, CrN is adopted as a metal having a relatively high slip property as compared with the base material 11 and the first metal layer, and therefore the second target 8 provided on the left side surface of the vacuum chamber 2. Is Cr. N contained in each metal layer is supplied from nitrogen gas, which is a process gas.

基材１１に対する金属層の被着の順序であるが、硬度が大きい金属の方が一般的に金属に対する被着性が良好であるため、本例において基材１１に最初に被着するのはＴｉＡｌＮとする。また、金属の被着工程はＣｒＮの被着で終了することにより、切削用工具の最表面をＣｒＮ層で覆うものとする。これは、基材１１の刃部以外の部分もすべり性の高いＣｒＮ層で覆うことにより、被削材がＣｒＮ層の高いすべり性で速やかに排出できるようにするためである。   The order of deposition of the metal layer on the base material 11 is generally higher than that of the metal having a higher hardness, so that the base material 11 is first deposited in this example. TiAlN. In addition, the metal deposition process is completed with CrN deposition, so that the outermost surface of the cutting tool is covered with a CrN layer. This is because the work material can be quickly discharged with the high slip property of the CrN layer by covering the portion other than the blade portion of the base material 11 with the high slip property CrN layer.

なお、第２の金属層と比較して相対的に硬度が大きい第１の金属層としては、ＴｉＡｌＮの他、ＡｌＣｒＮ、ＴｉＳｉＮ、ＣｒＳｉＮ、ＴｉＣＮ等の中から採用可能である。また、第１の金属層と比較して相対的にすべり性が良好な第２の金属層としては、第１の金属層と機械的性質が異なるように他の金属を選択する限りにおいて、ＣｒＮ、ＣｒＳｉＮ、ＴｉＮ、ＴｉＣＮ等の中から採用可能である。すなわち、ＣｒＳｉＮやＴｉＣＮは、切削用工具のコーティングに用いる金属として硬度及びすべり性の両方について採用しうる性能を有しているので、これらを硬度又はすべり性のために選択する場合には、他方の金属については、これよりもすべり性又は硬度が良好な別の金属を採用するものとする。   As the first metal layer having a relatively high hardness compared to the second metal layer, it is possible to employ TiAlN, AlCrN, TiSiN, CrSiN, TiCN, or the like. Further, as the second metal layer having a relatively good sliding property compared with the first metal layer, as long as another metal is selected so that the mechanical properties are different from those of the first metal layer, CrN , CrSiN, TiN, TiCN and the like. That is, since CrSiN and TiCN have performances that can be employed for both hardness and slipperiness as metals used for coating cutting tools, when these are selected for hardness or slipperiness, For this metal, another metal having better sliding property or hardness than this is adopted.

アークイオンプレーティング装置１を用いた金属層の形成について説明する。排気口３から真空チャンバー２内の空気を抜いて真空度を高め、供給口４からプロセスガスとしての窒素を導入する。図１に示すように、回転式テーブル５を回転させながら、真空チャンバー２の上方に設けられたターゲット７とアノード１０の間にアーク電源９によってアーク放電を発生させ、ターゲット７の金属であるＴｉＡｌを蒸発させる。蒸発したＴｉＡｌと雰囲気ガスである窒素から構成されたイオンが、負のバイアス電圧が印加された基材１１の表面に堆積し、第１の金属層であるＴｉＡｌＮを形成する。   The formation of the metal layer using the arc ion plating apparatus 1 will be described. The air in the vacuum chamber 2 is extracted from the exhaust port 3 to increase the degree of vacuum, and nitrogen as a process gas is introduced from the supply port 4. As shown in FIG. 1, while rotating the rotary table 5, an arc discharge is generated by an arc power source 9 between a target 7 provided above the vacuum chamber 2 and an anode 10, and TiAl, which is a metal of the target 7. Evaporate. Ions composed of evaporated TiAl and atmospheric gas, nitrogen, are deposited on the surface of the substrate 11 to which a negative bias voltage is applied to form TiAlN, which is the first metal layer.

次に、ターゲット７への通電を切って、ターゲット８に通電を切り替える。すなわち、回転式テーブル５の回転を継続しながら、真空チャンバー２の左側面に設けられたターゲット８とアノード１０の間にアーク電源９によってアーク放電を発生させ、ターゲット８の金属であるＣｒを蒸発させる。蒸発したＣｒと雰囲気ガスである窒素から構成されたイオンが、負のバイアス電圧が印加された基材１１に前工程で被着しているＴｉＡｌＮの上に堆積し、第２の金属層であるＣｒＮを形成する。   Next, the power supply to the target 7 is turned off and the power supply to the target 8 is switched. That is, while the rotation of the rotary table 5 is continued, an arc discharge is generated by the arc power source 9 between the target 8 provided on the left side of the vacuum chamber 2 and the anode 10 to evaporate Cr which is a metal of the target 8. Let Ions composed of evaporated Cr and nitrogen, which is an atmospheric gas, are deposited on the TiAlN deposited in the previous step on the substrate 11 to which a negative bias voltage is applied, and are the second metal layer. CrN is formed.

このように、基材１１を回転させながら、第１及び第２のターゲット７，８への通電を交互に切り替えて蒸着を各々必要回数だけ繰り返すことにより、基材１１の表面にＴｉＡｌＮ層とＣｒＮ層を積層して形成することができる。   As described above, while rotating the base material 11, the energization of the first and second targets 7 and 8 is alternately switched and the deposition is repeated as many times as necessary, whereby a TiAlN layer and a CrN layer are formed on the surface of the base material 11. Layers can be stacked.

各金属層の個々の厚さは、基材１１の表面粗さよりも小さいものとし、基材１１の表面の表面粗さによる凹凸が、金属層を被着しても当該金属層の表面に同様の凹凸として現れるようにする。具体的には次項の「実施例」で説明するが、各金属層の膜厚は、基材１１の表面粗さの１／２０以上１／３以下であるものとし、また両金属層の各膜厚の合計は１μｍ以上３μｍ以下であるものとする。   The thickness of each metal layer is smaller than the surface roughness of the base material 11, and the unevenness due to the surface roughness of the surface of the base material 11 is the same as the surface of the metal layer even if the metal layer is deposited. To appear as irregularities. Specifically, as described in “Examples” in the next section, the thickness of each metal layer is assumed to be 1/20 or more and 1/3 or less of the surface roughness of the base material 11, The total film thickness is 1 μm or more and 3 μm or less.

３．得られた金属層の構成
図３（ｂ）に、以上の製造工程で金属膜を形成した切削用工具の表面に垂直な面で切断した場合の模式的断面図を示す。基材１１の表面には硬度が大で金属に対する被着性が良好なＴｉＡｌＮ層１２があり、ＣｒＮ層１３と交互に積層した金属層が構成されており、基材１１の最表面はすべり性の良好なＣｒＮ層１３で覆われている。 3. Configuration of Metal Layer Obtained FIG. 3B is a schematic cross-sectional view when cut along a plane perpendicular to the surface of the cutting tool on which the metal film has been formed in the above manufacturing process. On the surface of the base material 11, there is a TiAlN layer 12 having high hardness and good metal adhesion, and a metal layer alternately laminated with the CrN layer 13 is formed. The outermost surface of the base material 11 is slippery. It is covered with a good CrN layer 13.

図３（ｂ）に示すように、２種類の金属層１２，１３が交互に重ねられた金属層の表面は、基材１１の表面と略同様の粗さが現れている。これを切削用工具として用いた場合には、図３（ｂ）中に切断線ａ−ａで示唆するように突出した部分が摩耗して表面が平坦に近い状態となり、図３（ａ）に示すように、切削用工具の表面には２種類の金属層１２，１３が交互に縞状に現れる。   As shown in FIG. 3B, the surface of the metal layer in which the two types of metal layers 12 and 13 are alternately stacked has substantially the same roughness as the surface of the base material 11. When this is used as a cutting tool, the protruding portion wears as suggested by the cutting line aa in FIG. 3B, and the surface becomes nearly flat, and the state shown in FIG. As shown, two types of metal layers 12 and 13 appear alternately in a striped pattern on the surface of the cutting tool.

このような状態になると、切削用工具としては、硬度の大きいＴｉＡｌＮ層１２による耐摩耗性と、すべり性の良好なＣｒＮ層１３による切削くずの排出性の両方の性能を高いレベルで発揮できることとなる。そして、累積総切削長が大きくなって切削用工具の摩耗が進んでも、ＴｉＡｌＮ層１２とＣｒＮ層１３が交互に縞状に現れた表面状態は依然として維持されるので、最終的にすべての金属層が摩耗して基材１１が露出するまで、良好な耐摩耗性及びすべり性が継続的に維持されて安定した切削を長期間継続することができる。   In such a state, as a cutting tool, both the wear resistance by the TiAlN layer 12 having a high hardness and the discharge performance of the cutting waste by the CrN layer 13 having a good sliding property can be exhibited at a high level. Become. Even if the cumulative total cutting length increases and the wear of the cutting tool advances, the surface state in which the TiAlN layers 12 and the CrN layers 13 appear alternately in stripes is still maintained, so that all the metal layers are finally formed. Until the substrate 11 is worn out and the base material 11 is exposed, good wear resistance and slip properties are continuously maintained, and stable cutting can be continued for a long time.

４．実施例
次に、以上説明した本例の切削用工具を実際に種々の条件で製造し、また単層の金属膜を有する切削用工具を比較例として製造し、これらを切削試験に供して互いに寿命を比較することにより、本例の切削用工具の構成において必要とされる膜厚等の諸条件について検討する。 4). Example Next, the cutting tool of the present example described above is actually manufactured under various conditions, and a cutting tool having a single-layer metal film is manufactured as a comparative example, and these are subjected to a cutting test and are used together. By comparing the lifetimes, various conditions such as the film thickness required in the configuration of the cutting tool of this example are examined.

（１）切削条件等
本実施例の切削用工具はＷＣ−Ｃｏからなり、外径１０ｍｍ、刃長２２ｍｍ、全長８０ｍｍ、シャンク径１０ｍｍのエンドミルであり、その表面粗さ１５００オングストロームの基材１１に、前述したようにＴｉＡｌＮ層１２とＣｒＮ層１３が交互に積層した合計厚さ３μｍの金属層を形成した。このエンドミルを実際に切削に供して寿命評価を行なった。切削条件は、被削材を機械構造用炭素鋼Ｓ５５Ｃとし、切削速度５０ｍ／ｍｉｎ、１刃当たりの送り量０．４４ｍｍ／刃、切り込み深さは径方向１ｍｍ、軸方向１５ｍｍとした。以上の条件で切削を行い、エンドミルの切刃の切削方向と反対側の面である逃げ面の摩耗量が０．２ｍｍに達した時をもって寿命とし、その時の切削長を記録した。なお、逃げ面の摩耗量が０．２ｍｍに達したか否かは切削長３〜５ｍごとに随時切削を中断して確認するものとした。 (1) Cutting conditions, etc. The cutting tool of this example is made of WC-Co, and is an end mill having an outer diameter of 10 mm, a blade length of 22 mm, a total length of 80 mm, and a shank diameter of 10 mm. The surface roughness of the substrate 11 is 1500 angstroms. As described above, a metal layer having a total thickness of 3 μm in which the TiAlN layers 12 and the CrN layers 13 were alternately laminated was formed. This end mill was actually subjected to cutting to evaluate the life. The cutting conditions were such that the work material was carbon steel for machine structure S55C, the cutting speed was 50 m / min, the feed amount per blade was 0.44 mm / blade, the cutting depth was 1 mm in the radial direction, and 15 mm in the axial direction. Cutting was performed under the above conditions, and when the flank wear amount on the side opposite to the cutting direction of the cutting edge of the end mill reached 0.2 mm, it was regarded as the life, and the cutting length at that time was recorded. Whether the flank wear amount reached 0.2 mm or not was confirmed by interrupting cutting every 3 to 5 m of cutting length.

（２）比較例
図４は、比較例であるＴｉＡｌＮを単層で３００００オングストローム（３μｍ）の厚さに形成した比較例の寿命評価試験の結果を示すものであり、寿命に達した時点での累積切削長（以下、単に切削長と呼ぶ）は５０ｍであった。 (2) Comparative Example FIG. 4 shows the result of a life evaluation test of a comparative example in which TiAlN as a comparative example is formed in a single layer with a thickness of 30000 angstroms (3 μm). The cumulative cutting length (hereinafter simply referred to as cutting length) was 50 m.

（３）実施例１
図５は、第１実施例であるＴｉＡｌＮ層１２とＣｒＮ層１３が交互に積層された多層膜の切削用工具であり、１層当たりの厚さを１０オングストロームから２０００オングストロームまで変化させて７種類製作し、それぞれ上述した試験を行なって寿命としての切削長の値を得た。同図中、○印を付したものが比較例と比較した場合に良好な結果と考えられるものであり、１層当たりの厚さが７５オングストロームで切削長が８０ｍ、１層当たりの厚さが２５０オングストロームで切削長が９０ｍ、１層当たりの厚さが５００オングストロームで切削長が９５ｍとなっている。この範囲について基材１１の表面粗さ１５００オングストロームと比較すると、金属層の１層当たりの厚さは、図５の表中の「１層当たりの厚さ」の欄中に膜厚の数値に並べて表記したように、基材１１の表面粗さの１／２０以上１／３以下であることが条件となる。 (3) Example 1
FIG. 5 shows a multi-layer cutting tool in which the TiAlN layer 12 and the CrN layer 13 according to the first embodiment are alternately laminated. The thickness per layer is changed from 10 angstroms to 2000 angstroms, and seven types are shown. Each was manufactured and the above-described tests were performed to obtain the value of the cutting length as the life. In the figure, those marked with ○ are considered to be good results when compared with the comparative example, the thickness per layer is 75 Å, the cutting length is 80 m, the thickness per layer is The cutting length is 90 m at 250 angstroms, the thickness per layer is 500 angstroms, and the cutting length is 95 m. Compared with the surface roughness 1500 angstrom of the substrate 11 for this range, the thickness per layer of the metal layer is the value of the film thickness in the column “Thickness per layer” in the table of FIG. As shown side by side, the condition is that the surface roughness of the base material 11 is 1/20 or more and 1/3 or less.

また、図５において、切削用工具の基材１１の表面粗さの１／２０未満、同１／３を越える範囲では、効果が得られないことも確認された。   Moreover, in FIG. 5, it was also confirmed that an effect was not acquired in the range of less than 1/20 of the surface roughness of the base material 11 of a cutting tool, and exceeding 1/3 of the same.

また、総膜厚は１μｍから３μｍが良好であり、これよりも薄いと摩耗が早くなり（切削長が短くなり）、またこれよりも厚いと膜厚が均一になりにくく、厚くなりすぎたところの金属層が剥離して基材１１から剥がれ落ちてしまう原因となる。第１実施例は総膜厚が３μｍの例であるが、同様の実験により総膜厚で１μｍ〜３μｍの範囲で効果が得られることが確認されている。   In addition, the total film thickness is good from 1 μm to 3 μm, and if it is thinner than this, the wear will be faster (cutting length will be shorter), and if it is thicker than this, the film thickness will be difficult to be uniform and too thick. This causes the metal layer to peel off and peel off from the substrate 11. The first example is an example having a total film thickness of 3 μm, but it has been confirmed by similar experiments that an effect can be obtained in the range of 1 μm to 3 μm in total film thickness.

図６は、本実施例における切削用工具の金属膜の状態を実施例の実際の寸法に従って表した図であり、同図（ａ）は表面粗さ約１５００オングストロームの基材１１の表面を示す図であり、同図（ｂ）は当該基材１１の表面に、１層当たり約５００オングストロームのＴｉＡｌＮ層１２とＣｒＮ層１３が交互に積層されて全体で約３００００オングストロームの金属層が構成されている状態を拡大して示したものである。従って、図６（ｂ）に示す構造によれば、一部省略して示しているが、各層ごとに３０層、合計６０層の金属層が積層した状態になり、最下層のＴｉＡｌＮ層１２は基材１１の凹凸に入り込んで確実に被着し、最上層のＣｒＮ層は基材１１と同様の凹凸を見せている。   FIG. 6 is a view showing the state of the metal film of the cutting tool in this example according to the actual dimensions of the example. FIG. 6A shows the surface of the substrate 11 having a surface roughness of about 1500 angstroms. FIG. 4B is a diagram in which a TiAlN layer 12 and a CrN layer 13 of about 500 angstroms per layer are alternately laminated on the surface of the substrate 11 to form a metal layer of about 30,000 angstroms as a whole. It is an enlarged view of the state. Therefore, according to the structure shown in FIG. 6B, a part of the structure is omitted, but 30 layers of each layer, a total of 60 metal layers, are stacked, and the lowermost TiAlN layer 12 is The uppermost CrN layer shows the same unevenness as that of the base material 11 by entering the unevenness of the base material 11 and reliably depositing it.

従って、図６（ｂ）中に下向きの矢印で示すように、切削に伴って金属層が摩耗して凹凸が均され、同図中に切断線で示すように表面が略平坦になると、同表面には、ＴｉＡｌＮ層１２とＣｒＮ層１３が交互に縞状になって現れることとなり、硬度の大きいＴｉＡｌＮ層１２による耐摩耗性と、すべり性の良好なＣｒＮ層１３による切削くずの排出性の両方の性能を高いレベルで発揮できる。切削用工具の摩耗が進んで金属層全体としての厚さが減じても、ＴｉＡｌＮ層１２とＣｒＮ層１３が縞状になって同一表面内に現れる状態は維持されるので、最終的に基材１１が露出するまでは、良好な耐摩耗性及びすべり性が継続的に維持されて安定した切削を長期間継続できる。   Therefore, as shown by the downward arrow in FIG. 6 (b), the metal layer wears with cutting and the unevenness is smoothed, and when the surface becomes substantially flat as shown by the cutting line in FIG. On the surface, the TiAlN layer 12 and the CrN layer 13 appear alternately in stripes, and the wear resistance due to the high hardness TiAlN layer 12 and the chip scraping performance due to the CrN layer 13 with good slipping properties. Both performances can be demonstrated at a high level. Even if the wear of the cutting tool progresses and the thickness of the entire metal layer is reduced, the TiAlN layer 12 and the CrN layer 13 are maintained in a striped state and appearing on the same surface. Until 11 is exposed, good wear resistance and sliding properties are continuously maintained, and stable cutting can be continued for a long time.

（４）実施例２
図７は、第２実施例であるＴｉＡｌＮ層とＣｒＳｉＮ層（ＣｒＳｉ中のＳｉ含有率３％）が交互に積層された多層膜の切削用工具である。その他の条件等は第１実施例と同一である。本例においては、１層当たりの厚さが７５オングストロームで切削長が８５ｍ、１層当たりの厚さが２５０オングストロームで切削長が９５ｍ、１層当たりの厚さが５００オングストロームで切削長が１００ｍとなっており、第１実施例よりも寿命が伸びている。これは、Ｓｉを添加したことにより膜の硬度がより高くなったためと考えられる。第１実施例と同様、本例においても金属層の１層当たりの厚さは基材１１の表面粗さの１／２０以上１／３以下であることが条件となる。その他の事項についても第１実施例と同様の結果が得られた。 (4) Example 2
FIG. 7 is a multilayer film cutting tool in which TiAlN layers and CrSiN layers (Si content 3% in CrSi) according to the second embodiment are alternately laminated. Other conditions are the same as those of the first embodiment. In this example, the thickness per layer is 75 angstroms and the cutting length is 85 m, the thickness per layer is 250 angstroms and the cutting length is 95 m, the thickness per layer is 500 angstroms and the cutting length is 100 m. Thus, the lifetime is longer than that of the first embodiment. This is presumably because the hardness of the film was increased by adding Si. Similar to the first embodiment, in this example as well, the thickness per metal layer is required to be 1/20 or more and 1/3 or less of the surface roughness of the substrate 11. Regarding other matters, the same results as in the first example were obtained.

なお、以上説明した各実施例では、切削用工具の基材１１の材質はＷＣ−Ｃｏであったが、高速度工具鋼でも同様の結果が得られた。また、本実施形態乃至実施例では、金属膜の形成にアークイオンプレーティング装置１を用いるものとしたが、アーク放電でなく電子ビーム等を用いて行なうイオンプレーティング装置や、その他の蒸着手段乃至手法を用いることもできる。   In each example described above, the material of the base material 11 of the cutting tool was WC-Co, but the same result was obtained with high-speed tool steel. Further, in the present embodiment through examples, the arc ion plating apparatus 1 is used for forming the metal film, but an ion plating apparatus that uses an electron beam or the like instead of arc discharge, other vapor deposition means, or the like. Techniques can also be used.

以上説明したように、本実施形態の切削用工具によれば、単層膜や、耐摩耗性を有する複数種類の金属膜を基材に積層して設けた場合に比べ、耐摩耗性と摺動性の両方に優れるため、工具の長寿命化が図れるとともに切削性が向上し、しかも長時間使用して摩耗が進行しても初期と同じ状態・性能を維持できるという効果がある。 As described above, according to the cutting tool of the present embodiment, compared with the case where a single layer film or a plurality of types of metal films having wear resistance are laminated on a base material, the wear resistance and the sliding property are reduced. is excellent in both of the dynamic properties, machinability is improved with longer life of the tool Ru Hakare, moreover there is an effect that wear prolonged use can maintain the same state and performance as the initial stage proceeds.
