How to adjust the burr of laser cutting machine cutting: what are the solutions to the burr of laser cutting machine?
In order to solve the problem of burrs appearing on the laser cutting machine, the following measures can be taken:
1. Equip air compressor and use auxiliary gas for cutting. Ensure that the gas is of high purity and consider changing to a better quality gas supplier. The purity of the gas is very important,laserpecker compact laser engraver do not use cylinders of gas as the purity will drop after two fillings and waste the gas. For laser cutting stainless steel, nitrogen is recommended as an auxiliary gas. Nitrogen is a flame-retardant gas, and during laser processing, nitrogen can not only prevent the bursting point phenomenon of laser cutting, but also the heated end face will not be oxidized instantly, and the cut end face will be smoother and brighter. The pressure of the auxiliary gas should be adjusted to 12-15 kilograms. Under this pressure, nitrogen will not completely prevent combustion, but can quickly blow away the waste material to achieve the effect of deburring.
2. Get a professional operator to debug the parameters of the metal laser cutting machine until it is normal, in order to successfully complete the cutting operation of the metal laser cutting machine.laserpecker 11 Some parameters of the laser cutting machine will also affect the appearance of the slag, which will lead to metal laser cutting machine burrs. Therefore, the cutting parameters should be adjusted accurately, air pressure, flow rate, focal length, cutting speed need to be adjusted many times, the parameters provided by the machine in order to cut a beautiful workpiece. Laser cutting machine is a precise machine, the operation is also a delicate work. Usually a data error will lead to abnormal operation of its work. Therefore, you must be strict in your work to minimize and avoid mistakes. Only when the equipment, gas and parameters are all tuned accurately, the cut workpiece can be burr-free, making the laser cutting machine cut better quality.
How to adjust the large burr of laser cutting machine cutting: what about the large burr of fiber laser cutting?
In the processing of stainless steel and aluminum-zinc-plated plate, burr problems may occur. If the above situation occurs, the first thing to consider when cutting mild steel burr factors, but to speed up the cutting speed is not easy, because the increase in speed will sometimes lead to the plate cut through the situation, especially in the processing of aluminum zinc plate. At this time, it is necessary to consider other factors of the machine tool, such as whether the nozzle needs to be replaced, whether the guideway movement is stable.
According to the working principle and design principle of fiber laser cutting, the following points are the main reasons for burrs on processed parts:
1. incorrect laser focus, need to test the focus position, according to the focus offset to adjust;
2. laser output power is not enough, you need to check whether the laser generator is working properly, if normal, observe the output of the laser control button, if the value is correct, adjust it;
3. cutting line speed is too slow, need to increase the line speed when running the control;
4. the cutting gas is not pure enough, need to provide high quality cutting working gas;
5. the machine running time is too long, the phenomenon of instability, this time you need to stop and restart.
Through the above measures and adjustment methods, can effectively solve the problem of laser cutting machine cutting burr, improve cutting quality and efficiency.
