The metal laser cutting machine is a mechanical equipment that uses the fiber laser as the encouragement source to output the particle beam with relative energy density, and focuses on the surface of the steel piece, so that the part of the area directly hit by the light spot on the steel piece can be melted and vaporized instantly, and the computer control mechanical system can move the direct light spot position to achieve automatic cutting. Those engaged in laser cutting processing technology know that optical fiber cutting machine has mechanical equipment for cutting carbon steel. The thicker the material is cut, the higher the output power of the equipment to be configured, and the more expensive the product will be. The thick steel plate optical fiber cutting machine has the advanced High neuro equipment integrating optical fiber laser cutting technology, numerical control processing technology and precision machine tool technology. Different equipment models and specifications, different main parameter configurations, and different prices. Generally, the higher the main parameters are configured, the more complete the functions of the equipment, the faster the efficiency of cutting metal plate materials, and the higher the price of optical fiber cutting machine. Optical fiber cutting machine is used in: sheet metal parts, metal products, sheet metal chassis, kitchen appliances, stainless steel products, precision hardware, auto parts, outdoor advertising light box, art, large toy manufacturing, packaging and other industries. Any kind of thermal cutting technology, except for a few cases that can start from the edge of the board, must generally pierce a small round hole in the board. Cutting precision is an important component of considering the effect of fiber laser cutting. The metal optical fiber cutter is generally 500W, which can cut 1mm to 6mm carbon steel, 1000W, 2300W and 3000W, respectively, which can cut 10mm and 20mm carbon steel. With the improvement of product quality requirements, manufacturers have a high awareness of the cutting precision requirements of Dongguan metal laser cutting machines. Therefore, how to achieve high precision in laser welding processing is a professional skill that many laser welding processing manufacturers need to master. The optical fiber laser cutting can only have a collimator after careful calibration. If there is no collimator cutting, the finished products will naturally be unqualified. However, the precision of optical fiber laser cutting is not entirely dependent on the equipment itself. The main parameters of the metal optical fiber cutting machine required by different manufacturing processes and processing materials are different. Therefore, when purchasing equipment, we must communicate with the manufacturer's technicians about the needs and fully listen to the suggestions of the optical fiber laser cutting manufacturer, so that we can purchase reassuring equipment and ensure that we can prevent problems before they happen.
