With the continuous improvement of cutting quality and precision of steel structure, in recent years, China's CNC intersecting line cutting technology has obtained considerable development.This technology is widely used in construction, chemical industry, shipbuilding, mechanical engineering, metallurgy, power and other industries of pipeline structural parts cutting processing.

From the perspective of equipment, CNC flame intersecting line cutting machine technology has been relatively mature, but because CNC flame cutting has some limitations, such as: cutting materials have limitations, can only cut carbon steel pipe, cutting speed is slow, low production efficiency.So its scope is shrinking.

In comparison, plasma intersecting line cutting machine has a better development prospect.Plasma intersecting line cutting technology has the characteristics of wide cutting range, cutting all metal materials, fast cutting speed and high working efficiency, which can overcome the above limitations of flame cutting.

The development trend of plasma intersecting line cutting in the future is to improve plasma power technology and solve the problem of matching between CNC system and plasma cutting.For example, the improvement of power supply can cut thicker materials; the development of fine plasma technology can improve the cutting speed, cutting quality and cutting precision; the improvement of CNC system can effectively improve work efficiency and cutting quality, etc., these problems remain to be gradually solved by relevant manufacturers and scientific research institutions.

From the application level of various CNC intersecting line cutting machines, the technology and performance of CNC intersecting line cutting machines developed and produced by ourselves in China have made gratifying progress, and are gradually catching up with and surpassing the international advanced level.Some domestic CNC plasma intersecting line cutting products have formed their own unique characteristics, in some aspects, the technical performance index even beyond the same kind of foreign products.

From the overall development trend observation, numerical control flame intersecting line cutting machine will maintain its basic market, it is difficult to do more, and numerical control plasma intersecting line cutting machine, will become our country for a long time in the future, the mainstream of steel structure pipe structure parts cutting market.
