CNC flame cutting machine is the use of digital program-driven machine tool movement, equipped with a flame cutting system, the use of numerical control systems to control the flame cutting system switches, cutting steel plates and other metal materials. This mechatronic cutting machine is a CNC flame cutting machine.
CNC flame cutting machines may encounter such problems in their daily operations. Beijing Hypertherm now concentrates on the data of various places and summarizes the problems that often occur. The following are the main defects in the quality of CNC flame cutting machines.
Uneven cut surface, that is, poor flatness slag on the cutting section or the lower edge of the hard-to-clean slag.
Cracks appear visible on the cut section, or pulsation cracks appear in the vicinity of the cut section, or cracks are only visible in the section.
Cutting edge quality defects: quality defects due to melting.
Roughness of the cut section The roughness of the cut section directly affects the processing quality of the subsequent process. The roughness of the cut section is related to the advance of the cut and its depth.
Plasma cutting machine arc voltage;
It is generally believed that the normal output voltage of the CNC plasma cutting machine is the cutting voltage. Plasma arc cutters typically have higher no-load voltages and operating voltages, and when using gases with high ionization energy such as nitrogen, hydrogen, or air, the voltage required to stabilize the plasma arc will be higher. When the current is constant, the increase of the voltage means that the arc ç„“ value increases and the cutting ability increases. If the diameter of the jet is decreased and the flow rate of the gas is increased while the enthalpy is increased, a faster cutting speed and a better cutting quality can be obtained.
