It is hard to break a steel bar by sawing it
On the contrary, in sawing hard (such as tool steel, alloy steel, pipe, sheet metal, iron etc.) material or thin material, should choose fine tooth saw blade. This is because the hard material in the sawing process is not easy to cut into, each saw a chip less, not easy to block Sairong groove. In this way, the sawing power of each tooth is small, and the number of teeth that the saw blade takes to increase is small, the sawing resistance is small, and the material is easy to be excised. Therefore, the saw is labor-saving and the sawtooth is not easy to wear. Special attention should be paid to the use of fine toothed saw blades in sawing pipes and thin materials so as to avoid the possibility that the saw teeth are caught and broken. Otherwise, the sawtooth will be hooked and broken because the pitch of the tooth is greater than the thickness of the plate. Therefore, we should hold a point: when sawing the workpiece, there are at least two cross sections at the same time, and sawing will prevent the hook from breaking
Coarse toothed saw blades shall be used in sawing soft and thick materials such as copper, bronze, cast iron, low carbon steel and medium carbon steel. This is because in the sawing of soft material or larger section, the larger the groove of the coarse toothed saw blade, the more of the chip per saw, and only when the chip slot is large, no jam occurs, and the sawing efficiency is affected.
The selection of the thickness of the saw blade: according to the size of the teeth, the serration, the middle teeth and the coarse teeth. In the process of using, it is necessary to choose the saw blade according to the hardness and thickness of the saw material, which is very important. Otherwise, the sawtooth of the saw blade will break or break. It will affect the normal processing of the workpiece and cause waste.
