This type of material has high strength, large tangential stress during cutting, large plastic deformation, and large cutting force. In addition, the thermal conductivity of the material is very poor, the cutting temperature increases, and the high temperature is concentrated in the cramped area near the cutting edge of the tool, thereby accelerating tool wear. Stainless steel and a small amount of high-temperature alloy stainless steel are easy to be processed and hardened during cutting, which is often several times that of ordinary carbon steel. The tool is cut in the tough area of processing, thereby shortening the tool life. Stainless steel or stainless steel is characterized by chip enhancement and high cutting temperature during processing. When the rebar saw blade passes through the front face, adhesion signs such as adhesion and welding will appear, which will affect the surface roughness of the processed parts.
The machining of stainless steel pipe fittings is tough: the machining tends to be strong when cutting, and the tool cuts in the tough area of the machining, which shortens the tool life.
Large cutting force and high cutting temperature: This type of material has high strength, large tangential stress and large plastic deformation during cutting, so the cutting force is large. The thermal conductivity of other materials processed by stainless steel pipe fittings is extremely poor, and the high temperature is often concentrated in the narrow and long area near the cutting edge of the tool, which accelerates the wear of the tool.
Stainless steel pipe fittings are easy to stick to the knife: any stainless steel has the characteristics of tough chips and very high cutting temperature during processing. When tough chips flow through the rake face, tool wear will accelerate.
Tool wear accelerates. The material generally contains high melting point elements, high plasticity, and high cutting temperature, which accelerates tool wear, sharpening and changing tools frequently, which affects production compliance and improves tool application costs. Contains a supporting platform and a pipe fixture, a moving device and a cutting device placed on the supporting platform. The moving device moves on the supporting platform along the axial direction of the pipe and mobilizes the cutting device to bevel the pipe. The pipe fixture is fixed on the tooling platform. , The pipe fixture is connected with the clamping oil cylinder, a torsion device and a positioning device are also arranged between the tooling platform and the supporting platform, and the moving device, cutting device, torsion device, positioning device and clamping oil cylinder are all connected with the controller.
