The impact, high temperature, and high pressure generated during high-speed metal cutting can easily cause wear, damage, failure, and locking screw breakage of milling cutters, and can also cause deformation of the tools, leading to their scrapping.

Especially for some large-diameter milling cutters and non-standard cutting tools, they are generally expensive due to the difficulty of manufacturing. The milling cutter head is prone to blade damage when cutting under harsh working conditions. When the blade breaks, the milling cutter head will also have a certain probability of damage, such as a deterioration of the blade positioning surface. If the cost of replacing the cutterhead increases, and if the cutterhead is not replaced, the lifespan of the blade will sharply decrease, and the processing cost of the workpiece will also increase.

The emergence of laser cladding repair technology can solve this problem. Laser cladding repair technology refers to the process of placing selected coating materials on the surface of a substrate using different filling methods, and then irradiating them with laser to melt them simultaneously with a shallow layer on the substrate surface. After rapid solidification, a surface coating with extremely low dilution and metallurgical bonding with the substrate material is formed, which significantly improves the wear resistance, corrosion resistance, heat resistance, oxidation resistance, and electrical properties of the substrate material surface.

The repaired tool can be reused. It can significantly improve its impact resistance, high temperature resistance, and can be repaired and reused after tool wear and damage. Laser cladding can repair cutting tools such as: wear on the positioning surface of milling cutters, wear on the positioning surface of milling cutters, wear on the positioning surface of U-drills, and various forms of metal cutting tools.
The precision and lifespan of the repaired tool have reached over 90% of the new tool, saving the enterprise more than 70% of costs, which is in line with the company's pursuit of high precision, high efficiency, high reliability, and bricklaying.
