​Laser cutting is a widely used processing method in the laser processing industry. The whole machine is stable and reliable, with good dynamic performance and strong load capacity. It is a high-tech product that integrates laser cutting, precision machinery, CNC technology and other disciplines, with characteristics such as high speed, high precision, and high cost-effectiveness. With the increasing use of laser cutting machines in various industries, operators of laser cutting machines need some necessary protective measures to avoid unnecessary injuries during industrial operations.

​In recent years, handheld laser welding machines have seen a significant increase in market share, mainly due to their high welding efficiency, good welding quality, simple operation, small welding seams, and time-saving characteristics. They have been widely praised in the welding field.

Fiber laser is the core equipment of fiber laser cutting machine, and its failure has a significant impact on the overall use of the machine. To reduce the failure rate of fiber lasers and minimize the losses caused to customers due to the shutdown of fiber laser cutting machines, attention should be paid when using fiber laser cutting machines.

There are many types of lenses used in fiber laser cutting machines, such as focusing lenses and protective lenses. During their operation, they may inevitably be contaminated, such as water pollution or dust pollution. Therefore, in daily maintenance, it is necessary to clean the laser lenses to ensure the stability of the laser cutting machine. Of course, cleaning lenses is not like cleaning glasses in our daily lives, and special attention needs to be paid. This article explains the correct cleaning method for laser lenses in fiber laser cutting machines.

1、 The steel strip should be kept in a tight state at all times The material of the steel strip belongs to steel. If the equipment is not tightened during operation, it is easy to cause the cut object to be thrown out, which poses problems for the equipment and operators. Therefore, the steel strip should be checked regularly to prevent any foreign objects or looseness. 2、 Check tool angle issues During the use of fiber laser cutting machines, it is necessary to adjust the cutting head angle in a timely manner when cutting different materials to ensure that there is no deviation in the cutting head, which will affect the qualified rate of cutting samples and increase production costs.

1. Replacement of water and cleaning of water tank It is generally recommended to clean the water tank and replace the circulating water once a week, and make sure that the laser tube is filled with circulating water before the machine starts working. Because the water quality and temperature of the circulating water directly affect the service life of the laser tube, it is recommended to use pure water and control the water temperature below 35 ℃. If the temperature exceeds 35 ℃, it is necessary to replace the circulating water or add ice to the water to reduce the water temperature (it is recommended that users choose a cooling machine or use two water tanks).

In today's digital and intelligent era, intelligence, precision, and efficiency have become important standards pursued by various industries.

Firstly, the laser is output using fiber optics, and then the marking function is achieved through a high-speed scanning galvanometer system. The electro-optical conversion efficiency is very high, which is very energy-saving.

​In modern industrial production, fiber laser cutting machines have become an efficient and accurate cutting tool. However, many users may encounter a problem - a decrease in power for fiber laser cutting machines. So, what is the reason for this? How should we solve it again?
