With the development of modern machinery industry, for cutting the quality and continuously improve the accuracy requirements, to improve production efficiency, reduce production costs, with automatic cut-off function of the requirements of high intelligence is also improved. Development of the cutter bar must be adapted to the requirements of modern machinery industry development. Bar cutting machines, a lot of species can be divided into round cutting, plasma cutting, laser cutting and so on. Among the fastest laser cutting efficiency, highest precision cutting, cutting thickness is generally small. The plasma cutting cutting speed quickly, but there is a certain slope cutting surface.

When buying a cutting machine, not only depends on the quality of the product, the most important thing is to choose a good manufacturer. There are a lot of cutting machine manufacturers in the market, all kinds of propaganda, what kind of publicity, all say their products are good. In fact, in the process of self-viewing, the quality of equipment produced by different manufacturers is also different. Even people who know a little bit will be trapped.
