Laser cutting has high processing efficiency, high speed, and high precision. However, as the life of the equipment is extended, the cutting speed is slow and the accuracy is poor. The problem is usually attributed to the decrease of laser power. In fact, it is not only the laser that affects the overall processing efficiency, but also other problems. laser engraving machine for sale

Focus position: It will affect the cutting accuracy, especially the diameter of the focal spot. The diameter of the focal spot should be as small as possible to produce a narrow slit. The diameter of the focal spot is proportional to the focal depth of the focal lens. The smaller the focal depth of the focal lens, the smaller the diameter of the focal spot.

Nozzle distance: The distance between the workpiece and the nozzle will also affect the power drop of the laser cutting machine. Too far away will cause unnecessary kinetic energy waste, too close distance will affect the dispersing ability of splash cutting products, the appropriate distance is 0.8mm. In addition, the laser cutting machine mainly randomly adjusts the processed parts, nozzles and processing with uneven cutting surfaces. The height of the pieces should always be consistent. laser engraving machine fume extraction system

Cutting speed: The cutting speed has a great influence on the power of the laser cutting machine, and it is proportional to the power of the laser cutting machine. At the same time, the cutting quality is related to the quality of the laser beam, and is also related to the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great influence on the quality of laser cutting.

Auxiliary gas: The size and pressure of the auxiliary gas will also affect the power of the fiber laser cutting machine. The auxiliary gas uses compressed air or inert gas. If the material thickness increases or the cutting speed is slow, the gas pressure should be appropriately reduced. Low pressure cutting can prevent edge cutting frost.

The first four items are the most common, and problems can be considered first. If it is excluded, you need to consider whether the equipment is partially aging. Of course, in addition, the size and thickness of the sheet will also affect the power of laser cutting. laser engraving machine fume extractor
