Plasma cutting machine has the advantage of more concentration, higher temperature, faster cutting speed, small deformation, but also cutting stainless steel, aluminum and other materials.
Plasma cutting of the shortcomings of the arc strong, noise, dust, and a certain amount of pollution to the environment, a lot of the use of water under the plasma cutting, cutting thickness also has a certain limit. Similarly, gas flow, arc length, telegraph quality, current size, cutting speed are affected by the quality of the master is not good, as the flame cutting simple. Plasma cutting gun is not much, because the cutting speed is faster, susceptible to the above-mentioned factors of the impact of the uncoordinated, so that cutting quality is different. In general, the thin plate cutting, plasma cutting incision surface quality is better than the fire filling cut, and hang slag few.
In recent years, foreign manufacturers have developed a new technology called fine plasma or high precision plasma, domestic manufacturers have introduced. Good results. By improving the design of cutting moment, the cutting surface quality of workpiece is improved remarkably, and the vertical degree of Shaoguan Edge can reach 0-1.5° is especially advantageous to improve the quality of thick plate cutting. Because of the improved cutting gun, the electrode life is increased several times. But the distance of the cutting gun is higher than the requirement of the steel plate, the height sensor of the gun is more sensitive, and the gun is quicker.
Therefore, the use of plasma cutting 4-30 mm steel plate is an ideal method, can avoid the oxygen b lack of cutting speed slow, large deformation, serious incision Rong, hanging slag serious and other shortcomings. Obtained a certain thickness of stainless steel and other materials of the blanking.
