With the continuous development of science and technology, superhard materials are increasingly used in industrial fields, such as aerospace, automobiles, energy and other fields. However, due to the extremely high hardness of superhard materials, traditional processing methods are difficult to meet the needs of efficient and high-precision processing. Laser technology, as an advanced processing method, has unique advantages in superhard material processing, which can effectively improve processing efficiency and reduce costs, and therefore has attracted much attention.
Advantages of laser technology in processing superhard materials
Superhard materials refer to materials with extremely high hardness, such as diamond, silicon carbide, boron nitride, etc. These materials have extremely high wear resistance, corrosion resistance and compressive strength, and therefore have important application value in many fields. However, due to the extremely high hardness of superhard materials, traditional processing methods such as mechanical processing and EDM are difficult to achieve efficient and high-precision processing, which has become an important factor restricting the application of superhard materials.
Laser technology is an advanced processing technology based on photonics. Its principle is to generate high-energy beams through stimulated emission light amplification to perform processing operations such as cutting, welding, and marking on materials. Laser has the advantages of high energy density, high precision, and non-contact, and can be widely used in the processing of various materials. In the processing of superhard materials, laser technology can achieve efficient and high-precision processing by quickly and locally heating the material.
Laser processing of superhard materials has the following advantages
High efficiency: Laser processing has high energy density and can quickly heat the material locally, thus achieving efficient processing. Compared with traditional processing methods, laser processing can greatly improve processing efficiency and shorten processing time.
High precision: Laser processing has the characteristics of high precision and high stability, and can achieve fine processing of superhard materials. At the same time, the laser processing process will not produce mechanical pressure on the material, reducing the possibility of workpiece deformation.
Environmental protection and energy saving: No cutting fluid or coolant is required during laser processing, which reduces environmental pollution and energy consumption. In addition, laser processing can also achieve non-destructive processing of materials and reduce material waste.
Strong applicability: Laser processing technology can be applied to the processing of superhard materials of various shapes and sizes, and has a wide range of applicability. At the same time, laser processing can also be combined with other technologies such as CNC machine tools, 3D printing and other technologies to achieve the processing of more complex shapes and structures.
