Plasma cutting surface is rough, cutting thick plate has advantages and low price. The laser cutting surface is smooth and the plasma is rough, so it is necessary to send someone to repair the burr. Laser cutting can cut thick plates above 3MM, and plasma can cut thick plates above 8 mm. Laser cutting has smooth surface, less compensation, higher precision and more expensive price.
In terms of cost, plasma is cheaper than laser 1/3. The cutting surface of fine plasma is thinner than that of laser, especially in Japanese equipment. The disadvantage of plasma is that the slit width is about 3 mm, and the most important part of plasma is power supply, which is equivalent to the laser of laser cutting machine. Plasma consumes a lot of electricity, and the electrode protection nozzles of common spare parts are also quite expensive, especially the electrode drilling is very expensive.
Plasma cutting machine is a new type of thermal cutting equipment. Its working principle is that compressed air is used as working gas and high-temperature and high-speed plasma arc is used as heat source, so that the cut metal is partially melted, and at the same time, the melted metal is blown away by high-speed airflow, forming a narrow gap. Plasma cutting machine can be used to cut various metal materials, such as stainless steel, aluminum, copper, cast iron, carbon steel and so on. It not only has the advantages of fast cutting speed, narrow slit, smooth cutting, small heat affected zone, small workpiece deformation, simple operation and so on, but also has remarkable energy-saving effect.
Ion cutting machine is suitable for the manufacture, installation and maintenance of various mechanical and metal structures, and is used for cutting, drilling, repairing and beveling of medium and thin plates. Plasma cutting is a machining method that uses the heat of high-temperature plasma arc to locally melt (and evaporate) the metal at the notch of the workpiece, and uses the momentum of high-speed plasma to remove the molten metal to form the notch. Plasma cutting machine is widely used in automobile, locomotive, pressure vessel, chemical machinery, nuclear industry, general machinery, construction machinery, steel structure and other industries!
Laser cutting is to scan the surface of material with high power density laser beam, heat the material to thousands to tens of thousands of degrees Celsius in a very short time to melt or vaporize the material, and then blow the melted or vaporized material away from the slit with high pressure gas to achieve the purpose of cutting the material. Laser cutting, because the invisible beam replaces the traditional mechanical cutter, the mechanical part of the laser cutter head is not in contact with the workpiece, and the working face will not be scratched during the working process.
Laser cutting speed is fast, the incision is smooth and flat, and generally no subsequent processing is needed; Small cutting heat affected zone, small plate deformation and narrow cut (0.1mm ~ 0.3 mm); The incision has no mechanical stress and shear burr; High machining accuracy, good repeatability and no damage to the surface of the material; Numerical control programming can process any scheme, cut the whole board in large format, and it is economical and time-saving without mold opening.
