Plasma cutting and laser cutting difference
The main difference between laser cutting and plasma cutting is the difference in cutting thickness and, of course, the difference in cutting operating costs. The advantage of plasma cutting is the ability to cut thick plates, and low prices, but cutting the price surface rough. Laser cutting surface smooth, high cutting accuracy, the price is more expensive than plasma cutting. The disadvantage of plasma cutting is that the cutting gap is large, about 3MM. The important part of plasma is the power supply, in fact, corresponding to the laser cutting machine laser, plasma power consumption is very large.
Plasma cutting machine is a kind of thermal cutting equipment, the main working principle is compressed air as the main body, high temperature and high-speed plasma arc as a heat source, will be cut metal partial melting, and at the same time with high-speed air flow will be melted metal blown away, forming a narrow cut. Plasma cutting machine can cut stainless steel, iron, aluminum, copper and other metal materials, and cutting speed, narrow seams, flat incuts. Plasma cutters are generally used in the construction, installation and maintenance of mechanical and metal structures.
Laser cutters are high-power, high-density laser beam scanning material surface, in a very short period of time can heat the material to thousands or even tens of thousands of degrees, can make the material melt or vaporize, and then use high-pressure gas to melt or other substances blown away from the cut. Laser cutting uses invisible beam instead of traditional mechanical knife, laser cutting speed, smooth incision, generally does not need post-processing, cutting is less affected by heat, plate deformation is small.
The difference of cutting accuracy, plasma cutting accuracy can reach less than 1mm, and laser cutting accuracy can reach within 0.22mm. In terms of cost plasma cutting machine is cheaper than laser cutting machine, in terms of processing accuracy, plasma cutting is equivalent to roughing, laser cutting is equivalent to fine processing.
