The difference between plasma cutting machine and CNC laser cutting machine
- Jul 31, 2017 -
1, plasma cutting development to the present, the working gas can be used on the plasma arc cutting characteristics and cutting quality, speed has a significant impact. Commonly used plasma arc working gases are argon, hydrogen, nitrogen, oxygen, air, water vapor and some mixed gases.
Plasma cutting machine is widely used in automobiles, locomotives, pressure vessels, chemical machinery, nuclear industry, general machinery, engineering machinery, steel and other industries!
2, laser cutting is the use of high-power density of the laser beam scanning the surface of the material in a very short period of time the material heated to tens of thousands to tens of thousands of degrees Celsius, the material melting or gasification, and then high-pressure gas will melt or gasification from Cut in the cut, to achieve the purpose of cutting materials. Laser cutting, because it is the use of invisible beam instead of the traditional mechanical knife, the laser part of the mechanical part of the work without contact, in the work will not cause scratches on the work surface; laser cutting speed, smooth incision, generally no need (0.1mm ~ 0.3mm); no mechanical stress, no shear burrs; high precision, good repeatability, no damage to the surface of the material; NC programming, cutting the heat of the small area, Can be processed arbitrary plan, you can format a large whole board cutting, no need to open mold, economical and time-saving.
