Fiber laser cutting machine is a high-precision and high-efficiency processing equipment that uses laser beams to cut and punch materials.

The working principle of fiber laser cutting machine is based on laser technology and mechanical transmission technology. Its working principle can be divided into the following parts: 1. Laser generation The laser in the fiber laser cutting machine is the core component for generating laser beams. Under the excitation of the pump source, the gain medium in the laser produces a transition between upper and lower energy levels, thereby releasing laser light. By adjusting the resonant cavity, the laser beam is focused in a specific direction to form a laser beam with high energy density. 2. Optical path transmission The laser beam is transmitted to the cutting head through optical elements such as reflectors and optical fibers. During the transmission process, the laser beam is focused and collimated to ensure uniform energy distribution of the laser beam and cutting accuracy of the cutting head. 3. Cutting head operation The cutting head of the laser cutting machine is a key component for realizing cutting operations. The cutting head is usually composed of a focusing lens, a protective lens, a reflecting lens, and a cutting nozzle. When the laser beam passes through the focusing lens, it is focused on a very small focus to form a light spot with high energy density. The light spot is irradiated to the surface of the material to be cut, causing it to melt instantly or reach the ignition point, and at the same time blowing the material away from the cutting line to achieve material cutting. 4. Transmission system The transmission system of the laser cutting machine is the key part to achieve material cutting and positioning. The transmission system usually uses synchronous belt drive or gear drive to transmit power to the workbench to achieve material feeding and positioning. Synchronous belt drive has the advantages of easy maintenance and low cost, but it also has certain errors and noise. Gear drive has the advantages of high precision, good stability and strong load capacity, but it also requires higher maintenance costs and more complex designs. 5. Control system The control system is the brain and soul of the laser cutting machine, which directly affects the cutting accuracy, speed and stability of the equipment. The control system is usually composed of a computer, a motion controller, a graphics processor and a sensor.

The computer is responsible for managing the operation and operation of the entire system, the motion controller is used to control the movement and positioning of the cutting head, the graphics processor is used to process the cutting graphic data, and the sensor is used to detect the feeding and position of the material. The advantages of laser cutting machines are mainly as follows: 1. High precision: The cutting precision of the fiber laser cutting machine is high, which can reach the micron level and is suitable for high-precision processing needs. 2. High speed: The cutting speed of the laser cutting machine is extremely fast, and a large number of cutting tasks can be completed in a short time, improving production efficiency. 3. Wide range of applications: The laser cutting machine can be applied to various materials, such as metals, non-metals, composite materials, etc., and has a wide range of applications. 4. High degree of automation: The fiber laser cutting machine can realize automated operation, reduce manual intervention, and improve production efficiency and product quality. 5. Environmental protection and energy saving: The laser cutting machine has low energy consumption and does not generate a large amount of waste and noise pollution, which meets the needs of modern green manufacturing.

In short, the working principle of the fiber laser cutting machine is based on laser technology and mechanical transmission technology. Its advantages are high precision, high speed, wide range of application, high degree of automation, environmental protection and energy saving. With the continuous development of science and technology, the application scope of laser cutting technology is becoming more and more extensive, and it has become one of the indispensable important equipment in the modern manufacturing industry.
