Advantage of plasma cutter
- May 01, 2018-
CNC plasma cutting machine has many advantages such as simple operation, high precision, high work efficiency and low labor intensity. It is widely used in many kinds of machining parts. CNC plasma cutting machines are often used in many industries, such as chemical machinery, automotive industry, general engineering machinery.
For materials that are difficult to cut in the traditional way, they can be done with a CNC plasma cutter. In addition, in the cutting speed, when cutting a small thickness ordinary carbon steel sheet, the numerical control plasma cutting speed is several times faster than the conventional oxygen cutting speed, and at the same time, the cutting surface remains smooth and the thermal deformation is good. The quality of CNC plasma cutting machine cutting parts has a very important influence on product quality, and scientific and reasonable optimization of cutting path has important value.
Analysis of Causes of Thermal Deformation of Cutting Pieces During the operation of the plasma cutting machine, the probability of occurrence of thermal deformation is small, however, it is difficult to avoid residual internal stress in sheet metal rolling and cooling. This is because, during the cutting process, due to the local high-temperature heat source factor, the metal sheet will expand along the cutting direction, and the mother board around the expanded metal sheet will be limited, resulting in the metal sheet in the slit. A large stress occurs at the position of the edge.
