During operation, the workpiece is clamped by the clamp, and then the saw frame descends to cut off the workpiece. The novel horizontal band sawing machine for the metal band on the market at present has relatively large defects in lifting and supporting aspects in the operation method of the novel horizontal band sawing machine:

1. lifting is mainly in two aspects of a main column and an auxiliary column, an included angle is formed between the support of the main column of the original sawing machine and the sawing beam, and an oil cylinder is vertically lifted, but the lifting force is decomposed into two forces due to the problem of the supporting position, and one lifting force is lifting and the other lifting force is pushing forward. Therefore, not only is the force wasted, but also a novel horizontal band sawing machine and an operation method thereof have forward thrust, and the force can cause unstable center of gravity and saw deflection of the machine tool, and the rising force also has unnecessary loss.

2. The original sawing machine is basically formed by welding rectangular pipes at the back of the saw beam at the position of the auxiliary upright post, and stress points are completely misaligned, so that the supporting force is too small, the structure is unstable, and the gravity center of the machine tool is unstable and the saw is deviated;
