Excellent Performance Of Diamond Saw Blade

Oct 30, 2017

With the rapid development of automobile, aviation and space technology, the requirement of material performance and processing technology is increasing. New materials such as carbon fiber reinforced plastics, particulate reinforced metal matrix composites (PRMMC) and ceramic materials are widely used.Diamond saw blade 

These materials have the characteristics of high strength, good abrasion resistance and small thermal expansion coefficient, which determines that the tool life is very short when machined. The development of new wear-resisting and stable superhard cutting tools is a research topic in many universities, research institutes and enterprises.Diamond saw blade

Diamond set mechanics, optics, heat, acoustics, optics and many other excellent performance in one, with very high hardness, small friction coefficient, high thermal conductivity, thermal expansion coefficient and low chemical inertia, is the ideal material for the manufacture of cutting tools. The development of diamond tool manufacturing methods in recent years is summarized. Processing of copper, zinc, aluminum and other non-ferrous metals and alloys, materials easy adhesion tool, processing difficulties.Diamond saw blade 

Diamond cutting tools can effectively prevent the bonding between metal and tool by using the characteristics of low friction coefficient and small affinity with nonferrous metals. In addition, because of the large elastic modulus of diamond, small deformation of the cutting edge, the cutting of non-ferrous metal extrusion deformation is small, the cutting process can be done under small deformation, so as to improve the processing surface quality.Diamond saw blade

With the advent of modern integration technology, machining to high-precision direction of development, the tool performance has put forward a very high demand. Because the diamond friction coefficient is small, the thermal expansion coefficient is low, the thermal conductivity is high, can cut the extremely thin chip, chip easy outflow, and other substances of affinity small, not easy to produce a chip, heat small, high thermal conductivity, you can avoid the impact of energy on the blade and workpiece, so the blade is not easy to passivation, cutting deformation small, you can get a higher quality surface.Diamond saw blade

Chemical vapor deposition method uses a certain method to activate the gas containing C source, and under the very low gas pressure, the carbon atoms are deposited in a certain area, and the carbon atoms form the diamond phase in the process of condensation and deposition. At present, the CVD method for the deposition of diamond mainly includes: microwave, hot filament, DC arc injection method and so on.Diamond saw blade
