CNC plasma cutting machine and CNC laser cutting machine are commonly used steel cutting equipment in mechanical processing plants. Fully understand the performance of CNC plasma cutting machine and CNC laser cutting machine, which can help users choose the cutting equipment that suits them. CNC plasma cutting machine works The CNC plasma cutting machine utilizes the heat of a high temperature plasma arc to rapidly melt the metal at the incision of the steel plate, and discharges the molten metal by the kinetic energy of a compressed gas (which may be argon, hydrogen, nitrogen, air, water vapor, and a mixed gas). A cutting process. Various shaped workpieces can be cut by the control of the numerical control system. CNC plasma cutting machine CNC laser cutting machine works The CNC laser cutting machine scans the surface of the workpiece with a high-power, high-density laser beam. In a short period of time, the workpiece can be heated to thousands or even tens of degrees Celsius, which can partially melt or vaporize the workpiece, and then use high-pressure gas. Melt or other material is removed from the slit. Various shaped workpieces can be cut by the control of the numerical control system. CNC laser cutting machine shape Laser cutting machine cutting workpiece Plasma cutting and laser cutting The main difference between plasma cutting and laser cutting is mainly reflected in cutting thickness, cutting quality, cutting precision and equipment cost. The cutting thickness plasma cutting machine is generally used for cutting workpieces up to 25 mm. Of course, the high-power configuration cutting thickness can also reach 80 mm, but for economical reasons, the particularly thick plate uses a flame cutting machine. Laser cutting machines are generally used to cut steel plates up to 16 mm. The thickness can also reach 30 mm (uncommon) depending on performance and power. Cutting quality The plasma cutting machine has a wide slit (generally about 3 mm), and the cutting section is rough and there are many burrs, which need to be polished. In addition, the plasma cutter has a large heat affected zone (smaller than a flame cutter). The slit of the laser cutting machine is narrow (about 0.3mm), and the cutting section is smooth and no further processing is required. The heat affected zone is smaller than the plasma cutting machine and has small thermal deformation. Large deformation Small deformation Cutting precision plasma cutting machine cutting accuracy of 1mm. Laser cutting machine cutting accuracy of 0.2mm. Under the premise that the equipment cost specifications are close, the cost of the laser cutting machine is generally 3.5 times that of the plasma cutting machine.
