Laser cutting machine is a device that uses laser to cut metal or non-metallic components. It has the advantages of fast processing speed, high accuracy and stable performance. However, many times the quality of the workpiece surface is not high after processing, so how do we improve this problem?
1. Check the wear of the conductive block of the cutting machine. The high-speed wire cutting machine must consider changing the cutting position of the conductive block or replacing the conductive block after 50~80 hours of processing. If there is dirt, it needs to be cleaned with detergent. It should be noted that when changing the position of the conductive block or replacing the conductive block, the verticality of the electrode wire needs to be corrected again to ensure the precision and surface quality of the workpiece.
2. Check the rotation of the guide wheel of the laser cutting machine. If the metal laser cutting machine is not good, replace it. Carefully check the damage and dirt of the upper and lower nozzles. If there is any dirt, clean it in time. If there is any damage, replace it in time. The cutting machine should also regularly check the condition of the wire in the wire storage barrel. If the wire loss is too high, it will affect the processing accuracy and surface quality, and it should be replaced in time. In addition, the poor condition of the conductive block, guide wheel and upper and lower nozzles will also cause the vibration of the wire electrode. At this time, even if the machined surface can discharge well, the machined surface is easy to produce wave peaks or stripes due to the vibration of the wire electrode, which will cause the roughness of the workpiece surface to become worse.
In recent years, users have paid more and more attention to the stability of the laser cutting machine. The stability of the laser cutting machine has a lot to do with its several important parts. With good quality parts, the metal laser cutting machine is naturally very stable when it is used. For the laser cutting machine, the pump source and crystal inside affect the life, which is actually the life of the lamp. Generally speaking, the life of lamps and crystals is equal to the standard. With the reduction of laser cutting machine energy, its processing performance will be greatly reduced, so the solution is to replace the pump light source and crystal.
1. When the laser cutting machine cuts materials, the working surface will release a lot of gas and splash, which will cause damage to the lens. When pollutants fall on the lens surface, they will absorb energy from the laser beam, resulting in thermal lens effect. If the lens has not formed thermal stress, the operator can disassemble it and clean it.
2. The power of the laser cutting machine drops suddenly, which may cause the glass tube to break. However, there are traces of watermarks on the wall of the broken glass tube. The power of air conditioner and air dryer can be increased to reduce the air humidity; In case of high temperature with high humidity, the glass may also break. No dirt or residue remains on the mirror surface; Dry with dry air; If necessary, roll the lens paper wetted with a few drops of acetone into a rod and gently scrub the lens surface to remove heavy dirt drops.
3. The cutting speed has a great influence on the power of the laser cutting machine, and the cutting speed is proportional to the power of the laser cutting machine. At the same time, the cutting quality is related to the laser beam quality, and also to the characteristics of the laser beam focusing system, that is, the size of the laser beam after focusing has a great impact on the laser cutting quality.
