Plasma cutting cannot avoid a large number of dust and iron filings. The square rails need a perfect cutting environment, otherwise the slide block will break quickly. Most importantly, slide block is costly. The advantage of V wheels is to ensure the same accuracy, not only more durable, but also easy to clean. At the same time our machine has an independent bearing platform.Due to the complex working conditions in the factory, the cutting table will cause deformation and lose cutting performance when loading thick plates. But our machine will not have this situation. Even it is crushed, no any influence on machine performance.
