Analysis Of Cutting Of Diamond Saw Blade For Material

Jul 03, 2017

     Superhard materials such as diamond and cubic boron nitride are often used in high speed machining processes and difficult cutting materials. This paper discusses and analyzes three aspects of superhard materials. First of all, the high speed milling of cast iron with PCBN makes its hardness and thermal conductivity good, and it is not easy to react with iron materials. Thermal cracking caused by thermal gradient difference is one of the technical problems in high speed milling. Secondly, the carbon fiber reinforced plastic (CFRP) is drilled by diamond plating tool. The CFRP material is used for aircraft fuselage, main structure and parts preparation. Carbon fiber in CFRP is of high hardness, so it is suitable to be machined with diamond-plated carbide tools. In the end, the direct milling of cemented carbide by means of Bl-Pc (no binder nanometer polycrystalline diamond) is discussed.Diamond saw blade
      It is a characteristic of composite materials to combine the matrix and reinforcing material to form the controllable mechanical characteristics. Carbon fiber Reinforced plastics (CFRP) is widely used in industrial machinery such as automobiles, helicopters, medical devices and railway vehicles for its superior tensile strength, humidity and corrosion resistance. In addition, the CFRP material in the Space field is a basic structural material, can reduce the aircraft fuselage weight, thereby improving fuel efficiency, saving maintenance costs.Diamond saw blade
      In the Aerospace field, diamond-plated tools are applied to processes related to CFRP materials. Precision Drilling for CFRP materials. Because of the axial force along the fibreboard lamination, the CFRP material is prone to delamination, with the increase of the cutting tool wear and the debris sticking on the cut edge, the drilling strength increases gradually, and the CFRP material is overheated and the strength is reduced. To solve this problem, it is unavoidable to apply to diamond plating.Diamond saw blade
      Construction of diamond plated diamonds. The vertex has three changes from the center of the bit to the edge, which reduces the axial force of the drill edge in the drilling, and minimizes the delamination of the CFRP material. The spiral angle and groove shape design have been optimized, the cutting edge has three vertices and the length is shortened; This design allows the temperature of drilling deep holes to be controlled, not too high.Diamond saw blade
