Application Of Laser Cutting Machine In Sheet Metal Processing (1)



With the rapid development of sheet metal processing technology, the domestic processing technology is also improving sharply, and the gap between foreign and prosperous countries is getting smaller and smaller. Many well-known foreign-funded enterprises have transferred their manufacturing bases to China, and at the same time, they also give sheet metal processing belts. There have been many reactionary ideas.


As a traditional sheet metal cutting equipment in sheet metal processing industry, there are mainly (CNC and non-CNC) shears, punching, flame cutting, plasma cutting, high pressure water cutting and others. These devices have a considerable market share in the market, one is well known, and the other is cheap, although they have obvious advantages in modern processes such as laser cutting, but they also have their own advantages.


(CNC) shears, because they are mainly cut in a straight line, can cut a sheet up to 4 meters in one knife, but it can only be used in sheet metal processing that only requires straight cutting. It is commonly used in industries where straight sheet metal cutting is required, such as straight cutting and flat cutting.


(CNC/turret) Punch has more sensitivity in curve processing in sheet metal processing industry. One punch can have one or more sets of square, round or other special request punches(mould), which can process some specific sheet metal work at a time in sheet metal processing. The most common is the chassis and cabinet industry. The processing technology they request is mainly cutting such as straight lines, square holes, and round holes. The pattern is relatively simple and fixed. They are mainly used for carbon steel plates of 2mm or less, and the width is usually 2.5mX1.25m. Stainless steel with a thickness of 1.5mm or more is generally not used because of the viscosity of the material. The advantage is that the processing speed of the simple pattern and the thin plate is fast, and the defect is limited when the thick steel plate is punched. Even if the punching is performed, the workpiece has a collapse appearance, the mold is required, the mold development cycle is long, the cost is high, and the flexibility level is not high enough. In foreign country,steel cutting beyond 2mm is generally cut by modern laser cutting, instead of punching.First, a thick steel plate is not good-looking when punching and shearing; and the second is thicker steel plate requiring more tonnage of punching, costing resources; Third, when the steel plate is thick, the noise is too high, which is not conducive to environmental protection.

As the original traditional cutting method in sheet metal processing industry, flame cutting has low investment requirements. In the past, the processing quality was not high. When the request was too high, a machining process could be processed, and the market was very large. Today it is mainly used to cut thick steel plates that exceed 40mm. Its drawback is that the thermal deformation is too large when cutting, the slit is too wide, the data is too expensive, and the processing speed is too slow, only suitable for roughing.
