Fiber laser cutting machine is a laser cutting machine that uses a fiber laser generator as the light source. Fiber laser is a new type of fiber laser that has developed internationally. It can output a high-energy density laser beam and concentrate it on the surface of the workpiece, causing the area illuminated by the ultra-fine focal spot on the workpiece to instantly melt and vaporize. The automatic cutting is achieved by moving the position of the spot illumination through a CNC mechanical system.

Fiber laser cutting machine is a laser processing equipment that uses a fiber laser generator as the light source. Fiber laser is a new type of fiber laser developed internationally. It outputs a high-energy density laser beam, gathers on the surface of the workpiece, and moves the spot irradiation position through a CNC machine tool system, causing the workpiece to instantly melt and evaporate in the ultra-fine focal length spot irradiation area, and achieving automatic cutting in this system. Compared with a large number of gas lasers, solid-state lasers have obvious advantages and have gradually developed into important candidates in fields such as high-precision laser processing, LiDAR systems, space technology, and laser medicine.

1. Regular maintenance of machine tools Machine tools are an important part of ensuring the stability of metal cutting laser machines. The running speed of the machine mainly depends on the coordination of the motor, reducer, and guide rail frame. Therefore, if we want to improve work efficiency, the maintenance of these components is indispensable. 2. Regularly replace optical lenses The laser beam is emitted by a laser device. Then the cutting head focuses to achieve the cutting effect. There are many optical lenses inside the cutting head. The laser beam is extended and focused through optical lenses. Due to the extremely harsh working environment of metal laser cutting machines, optical lenses can be contaminated by dust after prolonged operation. At this point, the transmittance of the laser will be greatly reduced, and the cutting efficiency will also decrease. Therefore, optical lenses also require regular maintenance and replacement. 3. Reasonably set cutting parameters In the process of using the machine, we need to cut patterns of different shapes. So the operator needs to modify the program parameters of the laser metal cutting machine. Due to the need for operators to set applicable cutting parameters. They need to be familiar with which parameters and programs are applicable to different materials. The higher the fit between laser cutting modes, the better the cutting quality. 4. Upgrade laser equipment Some customers tell us that the cutting efficiency is not enough when cutting thick plates. A more likely reason is that the power of the laser is too low. Therefore, if you want to achieve better cutting results, you may need to increase the laser power. That is to say, increasing laser power is an effective method. In the daily work process, operators must learn to record the small problems that often occur in metal laser cutting machines. Any device has a lifespan. Only diligent maintenance can ensure stable performance of your machine.

Fiber laser cutting machines are generally recommended to operate in a constant temperature environment. Only under constant temperature conditions can the normal operation and processing accuracy of the equipment be guaranteed. The semiconductor working temperature in the fiber laser cutting machine is required to be below 40 ℃. When the room temperature reaches 35 ℃, the internal temperature of the electrical cabinet can reach above 40 ℃. When the room temperature is too high, the failure rate of the CNC system will increase; Due to the use of distilled water as the cooling medium in the fiber laser cutting machine, the operating environment temperature of the laser should be above 5 ℃. Therefore, in order to ensure the good operation of the system, the ambient temperature should be controlled above 5 ℃, but not exceeding 35 ℃.

Hard alloy is an alloy material formed by combining refractory metals and hard compounds with metals through powder metallurgy. Hard alloys have a series of excellent properties, such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially their high hardness and wear resistance. Even if they remain basically unchanged at 500 ℃, they still have high hardness at 1000 ℃. Compared with steel, alloy materials are difficult to cut, mainly manifested in the following aspects.

The lenses used in laser cutting machines include focusing lenses, protective lenses, etc. These lenses are inevitably contaminated during operation, such as water pollution or dust pollution.

Solid state lasers appear in the form of fiber or disc lasers, with power levels similar to carbon dioxide lasers. The name of a fiber laser is determined by the laser active medium, in which case it is a glassy or crystalline solid in the form of fibers or discs.

Power and cutting thickness: Power refers to the amount of power that the laser can output, which directly affects the cutting depth and speed. Meanwhile, cutting thickness also affects the selection of power. If the material to be cut is thicker, the required power will also be correspondingly higher. Choose the appropriate power according to the required cutting materials and the thickness of the materials.

When you first come into contact with fiber laser cutting machines, regardless of whether you have relevant experience, you should be extra careful when operating such laser machines. When selecting cutting materials, choose familiar ones for simple use.
