The length of the diamond saw blade is determined according to the equipment requirements. The longer the saw blade, the greater its production capacity, but the lower the stability of the saw blade, the greater the cutting vibration and the lower the chip removal ability. The horizontal frame gang saw is longer than the vertical frame gang saw, but the latter is better than the former. The manufacturing process of diamond gang saw blades is basically the same as that of diamond welded saw blades. It also includes metal powder and diamond calculation, weighing, mixing, cold and hot pressing of saw teeth, welding surface grinding, preparation of saw blade steel core, cleaning and final welding of saw teeth, etc. Because the working condition of the diamond gang saw is different from that of the diamond circular saw blade, it reciprocates with the sawing machine. Therefore, the force of the diamond particles of the gang saw is different from that of the circular saw blade. The diamond particle action surface is on the front and back of the movement direction. Unlike the bumps of the coupling agent behind the cutting surface of the diamond particles in the circular saw blade, the diamond is firmly embedded. Therefore, in addition to a bond with a strong holding force, the diamond is also required to have high strength, otherwise the diamond particles will easily break when subjected to force, which reduces the cutting force. However, the high-strength diamond has a high crystal shape integrity rate, a smooth and flat surface, and it is difficult to stay in the bond for a long time, so it is necessary to use a high-strength diamond with a rough surface. The steel belt of the saw blade needs to be tensioned during installation. The average size is 8-12T/piece. The use of such a large tension force requires the steel belt saw blade to have a certain degree of rigidity and strength.
