Femtosecond Laser Machining Technology Theory
Femtosecond laser machining technology is a high-precision material machining method using ultrashort pulse lasers. It is mainly based on two core mechanisms: light transmission and light explosion. During the processing, the computer precisely controls the focus of femtosecond laser pulses on the surface or inside of the material，to produce a light explosion effect and achieve precise material removal.
Characteristics of carbide inserts
Carbide inserts are made of cemented carbide, which is an alloy material made of hard compounds of refractory metals and bonding metals through powder metallurgy. It has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance, and corrosion resistance. In particular, it can still maintain high hardness and wear resistance at high temperatures, making it an indispensable tool material in the manufacturing industry.
Application of Femtosecond Laser Machining of Carbide Inserts
Surface structure processing
Femtosecond laser is used to process microstructures on the surface of cemented carbide inserts, such as inverted tetrahedral pyramid structures, micron and nano groove structures, etc. These structures can improve the wetting characteristics, heat transfer, cooling and lubrication conditions of the inserts, reduce the generation of chip accumulation and scale, reduce the friction coefficient, and improve the cutting performance and fatigue resistance of the tool.
High precision cutting
The high precision and high stability of femtosecond lasers enable it to achieve micron-level or even nanometer-level cutting accuracy on carbide inserts, meeting the needs of high-precision machining.
Femtosecond laser processing can also achieve fine machining of the tool surface, such as removing burrs, improving surface roughness, etc., further improving the quality and performance of the tool.
