Floor diamond cutter, diamond saw blade, solid wood multi-layer diamond cutter
High speed steel tools classified by material; Carbide cutter; Floor diamond cutter; Other material tools, such as cubic boron nitride tools, ceramic tools, etc. In the diamond crystal, the four valence electrons of carbon atoms form bonds according to tetrahedral junctions, and each carbon atom forms covalent bonds with four adjacent atoms, thus forming a diamond structure. The connection force and target purpose of this structure are very strong, so that the diamond has extremely high hardness. The research shows that the larger the particle size of PCD, the stronger the anti-wear function of the tool. According to experts' estimation, the annual sales of PKD tools in the world will exceed. Cubic boron nitride tool (PCBN): CBN (cubic boron nitride) machine clamp blade, cubic boron nitride, molecular formula is BN, its crystal structure (Fig. is similar to diamond, hardness is slightly lower than diamond, hv72000-98000 MPa, commonly used as abrasive and tool materials.
It has always been an unsolved technical problem to regrind the circular arc of the worn floor diamond tool tip from scratch. Generally, the rake angle of diamond turning tool is 0 ° and can be selected within + 5 ° as required. During the mass production of cutting tools, there are some differences in the materials and materials of the work pieces of each tool. The reason is that the production of cutting tools will inevitably be affected by some customers, such as the grinding quality. Therefore, the cost resistance of cutting tools produced under the unified production situation will also be different. Conclusion PCD tools show advantages that are difficult to compare with other tools in non-metallic materials, non-ferrous metals and their alloys, metal matrix composites and other cutting scale due to their excellent processing quality and processing economy. In 1972, General Electric Company of the United States produced polycrystalline synthetic diamond and polycrystalline cubic boron nitride blades. Because PCD tools are often used for finishing machining of workpieces, the cutting thickness is small (sometimes even equal to the cutting edge radius of the tool), which belongs to micro cutting, and the machining quality is significantly affected by the rake angle and the rake face. The smaller rake angle and the higher rake face quality can play a major role in improving the machining quality of PCD tools.
At present, there is no suitable method to measure the roundness of the circular arc of the floor diamond cutter tip. CVD diamond thick film (TDF) welding tool the diamond thick film welding tool is to weld the laser cut CVD diamond thick film to the substrate (usually K-type hard alloy) once to form a composite sheet, then throw back the composite sheet, weld it to the cutter body twice, and grind the edge to the required shape and edge. For example, the PCD tool can be used to process the hypereutectic silicon aluminum alloy, a new piston material (the research on the processing mechanism of this material has been broken). However, since entering the new century, with the accelerated modernization of China's manufacturing industry, China's digital manufacturing technology has also achieved rapid growth. Welding methods mainly include laser welding, vacuum diffusion welding, vacuum brazing, high-frequency induction brazing, etc.
