In the sheet metal industry, an important process is metal cutting. Traditional methods include flame cutting and plasma cutting, etc. However, since the popularity of laser cutting machines, more and more sheet metal manufacturers choose laser cutting machines


What are the advantages of laser cutting machines compared to flame cutting and plasma cutting?


Flame cutting is the original traditional cutting method because of its low investment. In the past, the requirements for processing quality were not high. When the requirements are too high, a machining process can be added to solve the problem. The market is very large.

Now it is mainly used to cut thick steel plates over 40mm. Its disadvantages are that the thermal deformation is too large during cutting, the slit is too wide, the material is wasted, the processing speed is slow, and it is only suitable for rough processing.


Plasma cutting and fine plasma cutting are similar to flame cutting. The heat-affected zone is large, but the accuracy is much higher than that of flame cutting. The speed is also improved to a certain extent, and it has become the main force in plate processing. 


The actual cutting accuracy of the domestic top CNC fine plasma cutting machine has reached the lower limit of laser cutting, reaching a speed of more than 2 meters per minute when cutting 22mm carbon steel plates, and the cutting end surface is smooth and flat, and the slope is the best. Control within 1.5 degrees, the disadvantage is that the thermal deformation is too large when cutting thin steel plates, the slope is also large, there is nothing to do when the accuracy is high, and the consumables are more expensive.


The laser cutting machine is a technological revolution in sheet metal processing and the "processing center" in sheet metal processing. Laser cutting has a high degree of flexibility, fast cutting speed, high production efficiency, and short product production cycle, which has won a wide range of markets for customers. 


Laser cutting has no cutting force, no deformation, no tool wear, and good material adaptability. No matter it is simple or complex parts, it can be precision and rapid cutting; it has narrow slits, good cutting quality, high automation, easy operation, and labor Low strength, no pollution; automatic cutting and nesting can be realized, material utilization rate is improved, production cost is low, and economic benefits are good. 


The technology has a long effective lifespan. At present, laser cutting is used for most of the 2mm superstructured plates abroad. Many experts believe that the next 30-40 years will be the golden period for the development of laser processing technology.


From the above comparison of laser cutting machine, flame cutting and plasma cutting, the laser cutting machine performs better in sheet metal cutting, whether it is cutting accuracy, processing speed, and processing diversification. More and more sheet metal manufacturers have chosen laser cutting machines.
