[0002] Combined tooth shape bimetallic band saw blade is a specially designed metal cutting band saw blade, mainly with the following characteristics: composed of two different metals of tooth tip material and saw band material. Tooth tip usually adopts high-speed steel or other high-performance steel material, such as M42 (W2Mo9Cr4VCo8) high tungsten cobalt alloy tool steel, with high hardness, high wear resistance and high red hardness;Saw band material is low alloy spring steel, such as 46CrNiMoVA, with good toughness and fatigue resistance, can withstand repeated bending stress in sawing process.

[0003] The prior art such as laser cutting has very high machining precision and flexibility when slotting, and can realize complex tooth shape design. There is almost no mechanical stress in the machining process, which will not have negative impact on the performance of saw blade material. And laser processing is a non-contact processing, and the deformation of saw blade is small.

[0004] However, in the process of laser slotting, high-energy laser beam makes saw blade material melt and gasify instantaneously. Heat-affected zone is formed around the slotting area, which causes the microstructure of the material to change. For bimetallic band saw blade, the material performance of tooth tip and saw band may be affected to different degrees. For example, heat-affected zone may appear grain growth phenomenon, which reduces the strength and hardness of the material, especially for high-performance steel material of tooth tip part, such microstructure change may affect its wear resistance and cutting performance.
