Nowadays, with the rapid development of the laser industry, the optical fiber laser cutting machine has become the first choice to replace the traditional cutting process with its good cutting quality and efficiency, no pollution, no consumables in the metal cutting process and other advantages. However, the cutting quality and efficiency of fiber laser cutters with different components are still very different. When you want to buy a fiber laser cutting machine that suits your conditions, Chuyu Laser, a professional laser manufacturer, will show you the six most important components.
The most important six core components of optical fiber laser cutting machine
1st: Fiber laser
Fiber laser belongs to high-precision equipment and is the core power source of fiber laser cutting machine. It is also the most expensive part of the fiber laser cutting machine. When purchasing optical fiber laser cutting machine, we must pay special attention.
The laser used by the optical fiber laser cutting machine is mainly the optical fiber laser. At present, there are popular laser brands such as IPG, ROFIN and SPI in the international laser market. In the international laser market, high-value domestic brands such as Raycus and Max are becoming mainstream.
popular. As we all know, imported lasers are characterized by high purchase cost, long delivery time, high cutting quality and efficiency, low maintenance cost, long service life, etc. Compared with imported lasers, the domestic market price is lower. Therefore, the choice of imported or domestic brands of lasers is the best choice to meet our production requirements.

2nd: Laser head
Laser cutting technology uses the cutting head to focus the laser emitted by the laser into a high power density laser to cut the workpiece. The laser head is a laser output core device, which consists of a focusing lens, a focusing lens, a nozzle, a sensor and a control system. Among them, one of the key factors affecting the cutting efficiency is the shape of the nozzle in the cutting head and the characteristics of the flow field generated. Reasonable auxiliary gas type and flow field not only improve the processing capacity, but also limit the heat affected zone to a small range to ensure the processing quality.
In the process of laser cutting, the distance between the cutting head and the workpiece is a very important factor, which directly affects the cutting quality. In the cutting process, in order to avoid the nozzle, cutting head or workpiece damage caused by the collision between the cutting head and the workpiece protrusion, a special sensor must be installed on the cutting head to automatically detect the change of distance and automatically adjust accordingly. Therefore, the distance between the cutting head and the workpiece remains constant, thus ensuring stable cutting quality and improving process safety.
For different materials, the cutting head needs to be adjusted. A good cutting head can effectively improve the cutting effect and cutting speed. Poor cutting heads can't even cut on some materials. Therefore, we must choose a suitable laser head and adjust the height of the laser cutting head according to different materials to meet the needs of laser processing.

Third: CNC system
The control system is the main operating system of the optical fiber laser cutting machine, which mainly controls the machine tool to realize the movement of X, Y and Z axes, and also controls the output power of the laser. Its quality determines the stability of the operating performance of the optical fiber laser cutting machine. Through the precise control of software, the accuracy and cutting effect can be effectively improved. At present, Bochu CNC system, PIC CNC system and PA8000 system are commonly used.
PIC system is an old board control system, which can be integrated into ordinary computers to run, and uses background software to control the transmission of analog signals. Although the control system is older, it is a complete Kaiyuan system.
Bochu system is a laser cutting machine system developed by domestic personnel for the domestic market. It is a non closed loop tapping system developed for laser cutting machines below 2000W. It has many advantages, such as simple operation and rich functions, when used in laser cutting machines within 1000W. It is widely used in laser cutting machines below 1000W by most domestic manufacturers of laser cutting machines. After years of upgrading and testing, it has become a stable laser cutting machine system configuration within 1000W.
PA8000 system, PA system is an open CNC system based on PC technology. Open CNC technology represents the cutting-edge technology in the global CNC field. Its advanced technology has been adopted by many famous automation companies in the world.

4th: Engine
The motor of the laser cutting machine is the core component of the motion system. The performance of the motor directly affects the machining effect and production efficiency. At present, ordinary motors include stepping motors and servo motors. When purchasing, we need to configure the most appropriate motor according to the industry of the processing object.
1. The step motor of optical fiber laser cutting machine has a great influence on the precision of laser cutting. The starting speed is fast and the reaction is sensitive. Suitable for engraving and cutting. Stepping motor has many brands and different performances, so a good stepping motor is very necessary.
2. Servo motor is a very important part of laser cutting machine. Its quality directly determines the stability of the equipment. High quality servo motor can effectively ensure cutting accuracy, positioning speed and repeatability. At present, some servo motor brands are widely used in the production of laser cutting machines such as Mitsubishi, Fuji, Yaskawa, Panasonic and Delta.
For laser cutting machine, the key is to process the equipment according to the established figure, whether it is used for plate cutting or pipe cutting. Motor is the intermediate actuator of mechanical and control systems, which can compensate, optimize and coordinate the actions of various systems to achieve more perfect control. Therefore, the motor is also the most important issue when buying a machine.

5th: Bed frame
The stability and durability of the main structure of the optical fiber laser cutting machine are very important. High precision and high stability machine tools are conducive to improving the accuracy of laser cutting, so the requirements for machine tool stability are very high. It directly affects the cutting accuracy, efficiency and life of the equipment. Therefore, customers should pay special attention to the bed structure and material technology when purchasing optical fiber laser cutting machines. The current advanced bed technology in industry is heavy cast iron bed, because it has comprehensive properties such as wear resistance, corrosion resistance and shock absorption. And the effect of stress deformation is far lower than that of welded parts after heat treatment.

6th: Laser lens
Laser lens is the most widely used lens in the whole fiber laser cutting equipment. Many optical devices include laser lenses. Different lenses have different functions, such as total reflection lens, semi reflection lens and focusing lens. The quality of the lens directly affects the output power of the laser and the performance of the whole machine. If incorrect lens is selected, it will cause large laser loss, often damage the protective mirror, and the product quality is unstable, causing serious losses to the enterprise. Therefore, it is very important to choose appropriate protective glasses. Three steps are required to select the laser lens of the laser cutting machine:
1. Size matching.
2. You can choose K9 or quartz material according to different lasers and considering the use cost. In the process of practical application, professional manufacturers divide the two materials into multiple grades, and customers can select corresponding specifications according to actual needs.
3. Paint, select different technical parameters of paint according to the use environment.
Although the laser lens of the laser cutting machine is a vulnerable part, in order to improve its utilization and reduce production costs, the lens can be cleaned regularly to achieve the purpose of recycling.
