Traditional sheet metal cutting machine mainly includes (CNC and non CNC) plate shears, punches, flame cutting, plasma cutting, high-pressure water cutting, etc. With the development of sheet metal processing industrialization, laser cutting machine has become a very important machine in the sheet metal processing industry, and its application proportion is also increasing.

With the development of sheet metal industry and the improvement of manufacturing capacity of sheet metal enterprises, advanced laser machine in sheet metal industry has been constantly introduced. The application prospect of laser cutting machine  in sheet metal processing industry is very broad.

1. Traditional  Sheet Metal Processing Technology

Traditional sheet metal processing is completed by shearing, punching or flame plasma cutting process. In the face of orders with multiple varieties, small batches, customization, high quality and short delivery time, it has obvious shortcomings:

First of all, CNC shearing machine is mainly used for cutting plates, but it can only be used for sheet metal processing of straight cutting plates.

Secondly, CNC punch presses have requirements for thickness. They can only punch or cut steel plates less than or equal to 1.5mm, and the surface quality will be poor after processing, such as burrs, which is noisy and not conducive to environmental protection.

Thirdly, as a traditional cutting method, flame cutting will generate heat and deformation during the cutting process, and the width of the incision is large, which is a waste of plates, and the processing speed is slow, which is only suitable for rough processing of plates.

Fourth, the processing speed of high-pressure water cutting is slow, which requires water as an auxiliary, causing water pollution and high consumption costs.

2.Laser Cutting Technology For Sheet Metal

Laser is a kind of coherent light with great energy density and strong performance, and laser cutting technology is one of the most advanced processing technologies and processes in sheet metal processing.

Its main application principle is: focus the high-density and high-power laser on a point on the surface of the metal plate to be cut, and then convert the light energy into heat energy to cut the plate. With the continuous maturity and improvement of laser cutting technology, this technology is widely used in sheet metal processing operations, with very advanced application advantages.

3. Application Advantages Of Sheet Metal Laser Cutting Technology

Laser cutting technology uses programming software to optimize the process, improve the efficiency of laser cutting, and reduce the difficulty and intensity of work. At the same time, the usage of the die is reduced, thereby reducing the replacement time.

The optimized typesetting function of laser cutting can effectively reduce the processing time. Therefore, the arrangement of cutting scheme is more reasonable, and the processing efficiency and material saving are effectively improved.

The use of laser cutting technology can effectively reduce sheet metal processing procedures and production costs. The  laser cutting machine can not only improve the processing efficiency, but also improve the quality of the workpiece after processing. The input of the mould is reduced, and the cost is effectively reduced.

Because laser cutting technology has the characteristics of small cutting seam, fine density and smooth cutting position, it can complete cutting operation in a fast time. Therefore, the advantages of laser cutting technology should be given full play in sheet metal processing, so that high-precision and high-quality processing can be carried out smoothly
