What are the main advantages of hard coatings? Do you understand! Hard coating refers to the coating of wear-resistant tic or tin, HFN, Al2O3 on the surface of cemented carbide blade by chemical vapor deposition (CVD). The advantages of hard coating, coated carbide blades are generally made of indexable style. It can be clamped on the cutter bar or cutter body by machine clamping method. It has the following advantages:

1. Due to the high hardness and wear resistance of the coating material on the surface, the coated cemented carbide is allowed to use higher cutting speed compared with the uncoated cemented carbide, thus improving the processing efficiency; Or it can greatly improve the tool life at the same cutting speed.
2. Because the friction coefficient between the coated material and the processed material is small, the cutting force of the coated blade is lower than that of the uncoated blade.
3. When the coated blade is machined, the machined surface quality is better.
4. Because of the good comprehensive performance, the coated blade has good versatility. The blade with a coating brand has a wide application range.
