Band saw machine to enhance hardness is a necessary condition to improve cutting performance

The band saw machine enhances hardness as a necessary condition for improving cutting performance. At present, it is technically allowed to harden the cutting portion of the band saw blade separately, that is, by the electric spark strengthening method, the method of plating the hard alloy with the tip, the high-frequency quenching method or the grinding method by the grinding wheel, etc., the hardness of the saw blade itself is HRC35- 38, and the hardness of the cutting part can reach HRC60. The band saw blade has an elongation of 4 to 10%. In addition to being easy to carry and plucking, the saw blade can withstand the elastic fatigue caused by the band saw blade repeatedly bending during work. Therefore, the band saw blade must have appropriate toughness. The band saw blade is tightened on the saw wheel and there is a risk of breakage if the band saw blade does not have sufficient tensile strength. Therefore, the better the tensile strength of the band saw blade, the better its quality. The domestic band saw blade has a tensile strength of 140-160 kg/mm2. The durability of the saw blade refers to the performance of the saw blade that causes fatigue when resisting vibration and variable loads. This performance is particularly important for band saw blades. In general, the band saw blade is a factor that is worth considering. The durability of the saw blade is high or low, not only related to the carbon content, but also related to heat treatment, surface finish and corrosion. When the surface of the saw blade is rough or corroded, the durability of the band saw blade will be reduced by 30-50%.
