Detailed discussion of the strengths and weaknesses of laser cutting and traditional sheet metal processing

With the continuous growth of the sheet metal processing industry, sheet metal processing products have penetrated into every corner of our daily life. The surface roughness of sheet metal parts is not unfamiliar to people, but it is not easy to process such complex and precise parts with high precision. This is also one of the research and development directions of many domestic and foreign companies. As a link in the sheet metal manufacturing process, what is the manufacturing technology behind laser processing? What are the advantages and characteristics? Let's come together to find out.

Compared with traditional sheet metal processing methods, sheet metal processing shows higher cutting effects through laser cutting technology.

The surgical incision has a narrow width, a small heat-affected zone, a smooth surface, a fast cutting speed and a high degree of flexibility. It can freely cut various shapes, the material has a wide range of adaptability and many other advantages. This article mainly introduces the composition principle, hardware composition and software algorithm design method of the servo control system for laser cutting machines. In the manufacturing process of metal and non-metal materials, laser cutting technology has been widely used, which can not only significantly shorten the manufacturing cycle, but also reduce manufacturing costs and improve the quality of the final product. By using imported servo motors and transmission guide structures with excellent performance, excellent motion accuracy at high speed is achieved.

First, the laser has the ability to focus on very small light spots, which allows it to be used for small and high-precision processing, such as the manufacture of small gaps and micro holes.

Secondly, the laser has the ability to cut almost all materials, including two-dimensional or three-dimensional cutting of thin metal plates.

Finally, no tool is required during laser processing. This is a contactless processing method that does not produce mechanical deformation.

Therefore, in the sheet metal processing industry, it is undoubtedly the most appropriate to choose high-efficiency, high-energy and high-flexibility laser cutting technology, whether in terms of accuracy, processing speed or work efficiency. In modern manufacturing, laser cutting machines have been widely used. For those plates that are traditionally difficult to cut or have poor cutting effects, laser cutting technology can effectively solve these problems, especially when processing carbon steel plates, laser cutting technology occupies an indestructible position. Among the many laser cutting machines, CNC bending machines are widely used for their high efficiency, high quality and high precision. There are obvious differences between CNC bending machines and laser cutting technology. Laser cutting is done on ordinary machine tools, while CNC bending and shearing machines can achieve rapid prototyping. CNC bending technology is to bend cold metal sheets into workpieces of various geometric cross-sectional shapes by using equipped molds (whether general or special).

This technology is widely used in many industries such as light industry, container manufacturing, shipbuilding, automobile manufacturing, aircraft production, and railway vehicles, mainly for the bending of sheets. The most widely used in these fields is CNC bending machine. Bending machines can be divided into two categories: ordinary bending machines and CNC bending machines. At present, ordinary bending machines are widely used in China, but some companies also use CNC bending machines. In view of the high requirements for precision and irregular bending shapes, sheet metal bending in communication equipment is usually carried out by CNC bending machines. The core idea of this method is to use the upper die bending knife and the lower die V-groove of the bending machine to bend and shape the sheet metal parts.
