Description
Technical Field
The invention relates to the field of metal processing, in particular to a post-processing method of a hard alloy coating cutter.
Background
Cemented carbide is widely used as a material for various machining tools, called "industrial teeth", because of its high hardness and wear resistance. With the rise of high-end manufacturing industry and the emergence of various novel high-strength, high-hardness and high-toughness materials, metal cutting processing enters a new development stage represented by high-speed cutting, and the requirements on the quality and the performance of hard alloy are more and more strict. When the steel part is turned discontinuously, the cutting speed is high, the feed amount is large, the impact force is large, and the blade is easily abraded under high temperature and high pressure, so that the service life of the blade is shortened. The tool is typically coated with a coating to improve its performance and service life. One or more layers of hard films are coated on the surface of the cutter by physical and chemical methods, so that the hardness of the cutter can be effectively improved, the wear resistance and the heat resistance of the cutter can be improved, the cutting speed of the cutter can be greatly increased, and the service life of the cutter can be greatly prolonged.
However, with CVD (chemical deposition) coatings, the coating temperature is high, tensile stresses develop in the coating during cooling, and microcracks are highly likely to develop during cutting, leading to tool failure; the PVD (physical deposition) coating is finally deposited on the surface of the coating or embedded in the coating due to the fact that macroscopic large particles appearing in 'molten drops' exist in the target evaporation, so that the surface roughness of the coating is increased, the overall performance of the coating is reduced, the cutting resistance is large in the working process, the chip removal effect is poor, and the coating is more prone to wear and failure. Therefore, a method for improving the surface quality of the coating and improving the cutting performance of the cutter is needed.
