Tool coating technology collection

cemecon company: the "thickened coating" for cutting blades has been used for nearly ten years since the initial attempt to prepare PVD coating by thickened coating, and the successful application of this technology to indexable blades can be called a remarkable leap. For a coating with a thickness of only a few thousandths of a millimeter, what kind of coating is qualified to be recognized as "thickened" by experts? So far, most of the high thickness coatings are produced by CVD, with an average coating thickness of 10 μ M to 12 μ M, which is initially composed of tin, TiCN and the compound of alumina and another element

however, in practical application, with the increasing expansion of the demand range of materials, in order to more strictly adapt to the characteristics of coating materials, tool manufacturers often hope to choose composite materials such as aluminum, chromium and silicon, so as to equip their tool products with the best and most possible method, so as to meet the new requirements of customers. This needs the help of PVD technology. Moreover, the application of this technology can also obtain many advantages, such as super smooth coating surface and low treatment temperature. It can be said that it is entirely possible to innovate and develop new coating materials in the future by using materials such as aluminum, chromium, zirconium and others

cemecon company took the lead in launching supernitrides process solutions - this single structure composite coating product of oxygen and nitrogen combines the advantages of nitrogen coating and oxygen coating, and discards the defects of a single coating. Generally speaking, the production cost of nitrogen coating materials is relatively expensive, and although their mechanical properties are very good, they are still vulnerable to corrosion. On the contrary, oxygen coating has high chemical stability and low wear resistance. The new composite coating material can at least increase its aluminum content to 80mol% AlN, while the maximum molar content of the traditional coating material is only 65% AlN

will the increase of aluminum content lead to the decrease of mechanical properties? After verification, this phenomenon did not occur on products obtained through supernitrides process. On the contrary, the wear of supernitrider2c3 is reduced by 30 ~ 50% compared with the traditional AlTiN coating material, effectively extending the service life of the tool. At the same time, due to its high strength in the heating process, it ensures a high cutting speed, which means that more materials can be included in the category of dry machining

according to the cutting edge and the conditions of practical application, 3 can be produced by using PVD technology μ m、8 μ M even thicker coating. The advantages of thickened coating are also quite obvious: first, protect the substrate of the tool from the adverse effects caused by high temperature and other factors in the processing process. Secondly, the thickness of the coating is doubled, and the service life of the tool can be extended by 100% under the same application conditions

the guarantee capacity of new chemical materials has reached 63%. New blades for car processing: tigertec steel

Figure 2. Each coating is bonded and connected by a special intermediate layer

following the popular two-color coating indexable blades previously launched, Walter has launched a new blade for car processing tigertec steel. This new blade continues the excellent performance of Tiger Blade in milling and drilling applications. It has a smooth surface, enhanced toughness and friction, making the processing more stable and smooth. The new series of blades are the same as the previous products, with indicator coating to show the wear degree

the main difference between tigertec steel and other tigertec blades is that its coating thickness is 30% thicker than that of traditional tigertec blades, which enhances the stability of blade processing and reduces the degree of blade deformation. Each coating is bonded by a special intermediate layer (as shown in Figure 2), which ensures the adhesion of the coating during machining. With the help of the new coating, the side wear is reduced more effectively, which brings the performance of continuous and efficient machining, and can provide at least 30% performance improvement, while ensuring longer tool life

Figure 3 Comparison of side wear of different blades

Figure 3. As shown in Figure 3, a is the side wear of used WAP blades, and B is the used tigertec steel blades. The processing conditions are: the processed material is 56nicrmov7, the cutting speed is 230m/min, and the feed is 0.45mm. The local wear degree after 25 minutes is 0.7mm for WAP blade and 0.2mm for WPP blade

as cemecon claimed, in order to quickly adapt to the new machining requirements, it is very important to recognize its development trend at the early stage of technological development, and acetal leader seneras acquired most of the assets of conductive polymer manufacturer cool polymers Inc. For the tool coating industry, in order to achieve this goal, we must maintain close cooperation with tool manufacturers and users. Microcomputer shows that the process of meeting customer requirements and guiding customers' emerging needs is itself an endless cycle. Under the WPP new blade of Walter company, there are three brands of wpp10, wpp20 and wpp30, in order to provide customers with different processing quality with the help of these 4. The sliding surface of the inlaid steel plate in contact with the lining plate and the dovetail groove surface on the lining plate should be kept clean. There are three kinds of materials with different hardness and toughness
