1. The thickness of the saw blade should be selected according to the hardness and thickness of the processing material.

The

2. When sawing soft materials (such as copper, aluminum alloys, etc.) or thick materials, coarse-tooth saw blades should be used because of more sawdust and larger chip space.

The

3. When sawing hard materials (such as alloy steel, etc.) or thin plates and thin tubes, fine-tooth saw blades should be used, because the materials are hard, saw teeth are not easy to cut, there is less sawdust, and there is no need for large chip space; At this time, the sawtooth is easily caught by the work piece and breaks down. The number of teeth that need to work at the same time is more, and the force that the sawtooth bears is reduced.

The

4, medium-hardness sawing materials (such as ordinary steel, cast iron, etc.) and medium hardness of the workpiece, the general selection of medium saw blade.

The

It is recommended to choose fine teeth.
