Tool coating: A certain film is formed on the surface of the tool by chemical or physical methods, so that the cutting tool can obtain excellent comprehensive cutting performance, thereby meeting the requirements of high-speed cutting. Compared with uncoated tools, coated tools have significant advantages: it can greatly increase the life of cutting tools; effectively improve cutting efficiency; improve machining accuracy and significantly improve the surface quality of the processed workpiece; effectively reduce tool The consumption of materials reduces processing costs; the use of coolant is reduced to reduce costs, which is beneficial to environmental protection.
