As the world’s processing and manufacturing center, China has always attracted a large number of foreign enterprises to invest, as has the sheet metal industry. The market is becoming wider and wider. In order to quickly grasp the market demand, we need higher quality and efficient processing technology. Therefore, fiber laser cutting machines are more and more widely used in the sheet metal processing industry.
The high-tech fiber laser cutting machine will also become the main tool for the development of the sheet metal industry. With the continuous introduction of advanced laser equipment, the development of sheet metal industry is unstoppable. With the promotion of fiber laser cutting machine, the prospect of sheet metal processing industry is very broad.
As we all know, the sheet metal processing industry has experienced several generations of changes. In the era of sheet metal 1.0, at that time, the copper craftsman carried the burden to repair everywhere. In the 1970s, simple machining began to appear in people’s vision, and welding and other technologies became more and more mature. With the development of the times, the people’s increasingly improved living standards and accelerated pace of life require a more effective and rapid sheet metal processing method. The laser cutting machine was born. So why can laser cutting machines stand out among many processing methods? What are its advantages?
The traditional sheet metal processing technology of “cutting punching bending welding” or “flame plasma cutting bending welding” has low efficiency and poor quality, which shows obvious inadaptability to orders with multiple varieties, small batches, customization, high quality and short delivery time. As an alternative process of “shearing punching”, laser cutting has the characteristics of flexibility and high flexibility, and is often used to manufacture complex shaped or abnormal workpieces and samples (single piece or small batch).
Disadvantages of traditional sheet metal processing
- Traditional sheet metal cutting equipment occupies a considerable share in the market. Before the advent of laser cutting equipment, they made important contributions to the development of sheet metal industry. However, compared with modern technologies such as laser cutting, it has obvious disadvantages, which greatly affects the competitiveness of enterprises.
- Most of the traditional sheet metal blanking equipment uses a cutting machine, which can only be used for straight-line cutting and can not achieve complex shape cutting.
- Most of the traditional sheet metal punching equipment use CNC or turret punch, which limits the cutting of steel plates with a thickness greater than 1.5mm, and has poor cutting quality, high cost and noise, which is not conducive to environmental protection.
- As the original traditional cutting method, flame cutting is only applicable to rough machining, with poor cutting quality, slow speed, large thermal deformation and easy to generate waste.
Plasma cutting is similar to flame cutting. When cutting thin steel plates, the thermal deformation is large and the slope is large. It cannot be used when the accuracy is high, and the consumables are expensive.
Advantages of laser cutting - Laser cutting has high flexibility, fast cutting speed, high production efficiency and short product production cycle. No matter simple or complex parts, laser can be used to realize one-time rapid prototyping cutting;
- Narrow cutting seam, good cutting quality, high degree of automation, simple operation, low labor intensity and no pollution;
- It can realize automatic cutting layout and nesting, improve material utilization, no tool wear, and good material adaptability;
- Low production cost and good economic benefit.
The application advantage of laser cutting technology in sheet metal processing can simplify the processing procedure, shorten the product R & D cycle, improve work efficiency, and reduce the processing cost, thus helping enterprises to create more high-quality sheet metal processing workpieces. Therefore, in the actual processing, we should also correctly understand the application advantages and characteristics of laser cutting technology in sheet metal processing, and constantly improve its utilization rate, so as to process more high-quality workpieces and lay a good foundation for its further application, so as to continuously meet the industrial development and the needs of consumers and create higher economic and social benefits.
