Carbide Gear Cutter Made In zhuzhou China
The coating acts as a chemical and thermal barrier, reducing diffusion and chemical reactions between the tool and the workpiece, thereby reducing alveolar wear. Coated carbide cutting tools have the characteristics of high surface hardness, good wear resistance, stable chemical properties, heat and oxidation resistance, low friction coefficient and low thermal conductivity, which can increase the tool life by 3 to 5 times compared with uncoated tools during cutting. Above, increase the cutting speed by 20%~70%, improve the machining accuracy by 0.5~1 level, and reduce the tool consumption cost by 20%~50%. Therefore, coated tools have become the symbol of modern cutting tools, and the proportion of use in tools has exceeded 50%. At present, various tools used in cutting processing, including turning tools, boring tools, drills, reamers, broaches, taps, thread combs, rolling heads, milling cutters, forming tools, gear hob and gear shapers, etc. Coating processes can be used to improve their performance.
Practice has proved that a very thin wear-resistant layer is deposited on the surface of cemented carbide with good toughness, that is, coated cemented carbide, which can better solve the contradiction between wear resistance and toughness of cemented carbide.
