The two ends of the rotating shaft are respectively installed on the opposite wall of the through hole, and the motor drives the saw disc to rotate to cut the plate set on the machine tool. When the plate cutting machine is in working condition, the plate moves along the working surface of the machine tool, but the chips produced by the saw disc during the cutting process will be brought to the upper surface of the machine tool by the saw disc, which will bring inconvenience to the later cleaning work and also affect the machine tool. The flatness of the upper surface affects the cutting quality and precision. Moreover, the cutting tool is installed on the upper surface of the machine tool, and after the cutting tool is damaged, it is inconvenient to maintain or replace.

The movement of the plate along the upper surface of the machine tool is usually manually pushed by the operator to move the plate, which will make the operator move closer to the saw disc, which will not only increase the workload of the operator, but also pose a huge safety hazard, which is easy to be cut. The chips are accidentally injured, and at the same time, the cutting quality of the plate will be reduced.
