Definitions
- the invention relates to a cutting tool with a base body and a multi-layer coating applied thereto.
- cutting tools used usually consist of a basic body on which a one- or multi-layer coating is applied to increase the service life or to improve the cutting properties.
- Materials used for the basic body are, for example, hard metal, cermet, steel or high-speed steel.
- the coatings often comprise nitridic compounds, but also metallic hard material layers, oxide layers and the like.
- Various methods are used to apply the coating. These include CVD (Chemical Vapor Deposition) and PVD (Physical Vapor Deposition) processes.
- crankshafts or camshafts are made very high demands on the tools due to the material properties of the workpiece.
- cast or forged shafts are usually further processed by milling.
- the crankshaft cutters or camshaft cutters used are subject to high thermal and mechanical cyclic loads.
- the service life of the tools is mainly limited by a combination of ridge cracking and subsequent crater wear, which begins at the comb cracks.
- CVD-coated tool steels are known for tools for the above-described high thermal and mechanical cyclical stresses, but due to the high coating temperature they have disadvantages in terms of comb crack resistance.
- the inherently high resistance of the CVD-coated tool steels relative to crater wear is relativised.
- the use of a nitridic compound for the PVD coating of known tool steels results in scoring caused by tribochemical wear.
- Tribochromic wear means that friction occurs at the contact points between the tool and the machined material, resulting in a chemical reaction that results in a chemical and structural change in machined material and tool steel, resulting in wear of the tool.
- the object of the present invention was to provide, compared to the prior art, improved cutting tools which have increased resistance to comb cracking, tribochemical wear and consequent scoring.
- a cutting tool with a base body and a multi-layer coating applied thereto, wherein the base body consists of a hard metal, which
- the indicated average grain size refers to the tungsten carbide (WC).
- NbC and TaC serve to adjust the texture and the desired ratio of hardness and toughness.
- the layer applied to the second layer of aluminum oxide consists of TiAIN.
- the last further layer of aluminum oxide applied is thus.
- an outer layer of ZrN has a different hue compared to the basic body and the coating of TiAIN and aluminum oxide.
- the free surfaces get due to partial removal of the top layer of ZrN wear marks. As a result, it can be determined with the naked eye whether a cutting edge has already been used.
- the main body consists of a hard metal, which comprises 6 to 8 wt .-% Co, 1 to 2 wt .-% TaC, 0.2 to 0.3 wt.% NbC and the remainder WC.
- This composition in combination with the coatings according to the invention, is particularly suitable for high thermal and mechanical cyclic stresses. It does not include any other hard materials.
- the tungsten carbide (WC) in the cutting tool according to the invention is furthermore preferred for the tungsten carbide (WC) in the cutting tool according to the invention to have an average particle size of 2 to 3 ⁇ m.
- the mean grain size of WC affects the ratio of hardness and toughness. Although a larger average grain size leads to greater hardness, but at the same time the toughness is greatly reduced. Although a smaller mean grain size causes greater toughness, at the same time it also causes a slight loss of hardness.
- the first layer of TiAIN has a layer thickness of 2 to 4 ⁇ m and / or the second layer of aluminum oxide has a layer thickness of 1 to 2 ⁇ m. Due to the layer of TiAIN with the stated layer thickness, a desired ratio of hardness to toughness is set. The layer of aluminum oxide with the mentioned layer thickness causes high temperature and oxidation resistance and thus leads to tribochemical wear resistance. - A -
- the cutting tool comprises a coating, wherein the optional further layers, which consist alternately of TiAIN or aluminum oxide, have a layer thickness of 0.1 to 0.3 ⁇ m and / or the optional outer layer of ZrN Layer thickness of 0.1 to 0.6 microns.
- the coating has more interfaces, which leads to an increase in the toughness, but not the hardness.
- n 6
- a higher number of layers would indeed lead to an increase in the toughness.
- these layers usually have a compressive stress. Therefore, a larger number of layers would possibly result in an unstable coating that flakes off.
- the application of a large number of alternating layers of TiAIN or aluminum oxide in the PVD process is very complicated in terms of process engineering, so that there is also a limit to this on an industrial scale.
- the total layer thickness of the coating is preferably 2 to 8 ⁇ m and more preferably 3 to 6 ⁇ m.
- a thinner coating would not have the sufficient number of atomic layers to provide good wear protection.
- a thicker coating would be less stable due to compressive stresses of the individual layers and would possibly chip off, especially at the edges.
- the coating under the outer layer of ZrN preferably has a layer of substoichiometric ZrN 1-x , where x is 0.01 to 0.1 and the layer thickness of the layer is between 0.001 and 0.1 ⁇ m.
- the substoichiometric ZrN 1-x layer adheres less well to the top layer of alumina than ZrN, thus facilitating removal of the ZrN layer along with the underlying ZrN 1-x layer. As a result, wear marks occur even at the first use of the cutting tool, which indicates that the tool is not unused.
- Cutting tools have rake faces, cutting edges and open spaces.
- only the coating on the free surfaces preferably comprises an outer layer of ZrN and optionally a layer of substoichiometric ZrN 1-x under the outer layer of ZrN.
- the different coatings are produced by first coating the entire cutting tool with ZrN and then completely removing the layer of ZrN by brushing and / or (cleaning) blasting from the rake face and, as a rule, also from the cutting edge. If the layer of ZrN remains on the cutting face of the cutting tool, this can impair the removal of the chips.
- the removal is done by applying a layer also simplified from substoichiometric ZrN 1-x under the outer layer of ZrN, since the substoichiometric ZrN 1-x layer adheres less well to a layer of alumina than the ZrN outer layer.
- the ratio of Al to Ti in the layers consisting of TiAIN is from 60:40 to 70:30 and preferably 67:33. It is the atomic ratio (at%). This ratio requires a particularly good adhesion of the layers of aluminum oxide on the layers of TiAIN and thus a prolonged life.
- the object is further achieved by the use of a cutting tool with the above described properties for inserts or special inserts in crankshaft milling or camshaft milling.
- a cutting tool is exposed to high temperatures and high speeds when milling crankshafts because the machine utilization is particularly high. This requires a particularly high thermal shock resistance of the cutting tool, which causes a high Kammrissfesttechnik.
- the coating further comprises on the second layer of aluminum oxide additionally n alternatingly superimposed layers of TiAIN and layers of aluminum oxide, each having a layer thickness of 0.1 to 0.5 microns, where n on each one Layer and is an even number from 0 to 10, wherein the total layer thickness of the coating is 2 to 16 microns and the coating is produced in the PVD process, a particularly good resistance to thermal and mechanical Wechs The stress that occurs when milling crankshafts and camshafts has.
- Example 1
- a cutting tool comprising 8% by weight of Co, 1.15% by weight of TaC, 0.27% by weight of NbC and 90.58% by weight of WC was provided with a seven-layer coating :
- the substrate was additionally cleaned in alcohol and prior to depositing the layers in the vacuum chamber with Ar ion bombardment.
- TiAIN was carried out in an arc with 65 A evaporator flow per source at 3 Pa nitrogen and a bias voltage in the DC mode of 40 V and a temperature of about 550 0 C.
- the deposition of alumina was carried out in the reactive magnetron with a specific cathode power of about 7 W / cm 2 at 0.5 Pa Ar and oxygen as a reactive gas (flow about 80 sscm), with a bipolar pulsed bias voltage (70 kHz) of 150 V and a temperature of about 550 0 C.
- ZrN was deposited in the arc with 65 A evaporator current per source, at 3 Pa nitrogen and a bias voltage in the DC mode of 40 V and a temperature of about 550 0 C.
- Example 1 For comparison, a conventional CVD coating was applied to a substrate according to Example 1.
- the coating consisted of the following layers: 1. TiCN applied with a layer thickness of 5 ⁇ m in the mtCVD process
- the application was made according to a standard protocol for thermal CVD. It is a cutting tool for crankshaft milling and camshaft milling, as it is currently available in the trade.
- Example 1 In a milling trial on a workpiece made of 25MnCrSi VB6 steel, in which crankshafts were completed, the cutting tools of Example 1 were compared with those of Example 2.
- crankshafts of Example 1 With the cutting tools of Example 1 according to the invention more crankshafts could be milled to the end of life than with the comparison tools.
- the end of life is defined here after compliance with the dimensional accuracy of the component and the formation of chips. At a predetermined deviation from the dimensions desired on the component, the end of life has been reached.
