Laser pipe cutting machines generally have two functions: hole opening and cutting. This is the work processed in the program. In addition, there is a distinction between pipe feeding and feeding, which are divided into automatic mode and semi-automatic mode. The automatic mode is automatic feeding, and the semi-automatic mode is manual feeding, automatic clamping and feeding. There is a certain difference between the two. Compared with traditional manual cutting or saw blade cutting, it has certain advantages in production efficiency, that is, higher production efficiency. In particular, the comparison of large-diameter pipes will be more obvious, and the laser pipe cutting machine is controlled by CNC programming, so the production and processing accuracy is higher than the general manual or saw blade, because the manual error is large, the saw blade cutting also has the defect of saw blade offset.
