In metal processing, the optical fiber laser cutting machine, with its advantages of high efficiency and high quality, has gradually replaced the traditional process and become a sharp weapon in the metal processing industry.

But even if they are also called fiber laser cutting machines, the processing efficiency and effect of different equipment inside will vary greatly. For fiber laser cutting machines, the six core accessories must be considered when purchasing.

1. Fiber laser

Laser is the core "power source" of laser equipment, just like the automobile engine, it is also the most expensive part in the fiber laser cutting machine. At present, fiber lasers are mainly imported from Germany, Europe and the United States. With the development of technology, many brands of domestic lasers are emerging and gradually recognized by the market with high cost performance.

For a long time, China's lasers have basically relied on imports, which are expensive and have a long supply cycle, leading to the high price of high-power fiber laser cutters. The appearance of a hundred flowers blooming in China's fiber laser manufacturers has broken the monopoly of foreign enterprises in the laser field and directly lowered the price of imported products.

2. Cutting head

The cutting head is the laser output device of the optical fiber laser cutting machine, which is composed of a nozzle, a focusing lens and a focusing tracking system. The cutting head of the laser cutting machine will walk according to the set cutting path, but the height of the laser cutting head needs to be adjusted and controlled under different materials, different thicknesses and different cutting methods.

3. CNC system

The control system is the leading operating system of the optical fiber laser cutting machine, which mainly controls the machine tool to realize the movement of X, Y, Z axes, and also controls the output power of the laser. Its quality determines the stability of the operation performance of the optical fiber laser cutting machine. The accuracy and cutting effect can be effectively improved through the accurate control of software. At present, there are Beckhoff CNC system, PA CNC system, Farian card system, etc.

4. Motor

The motor of the laser cutting machine is the core component of the motion system. The performance of the motor directly affects the product processing effect and production efficiency. At present, the commonly used motors include stepping motor and servo motor. The most suitable motor is configured according to the industry type and product type of the processing object.

Stepping motor: fast starting speed, sensitive response, suitable for engraving and cutting with low requirements. The price is low. There are many brands of stepping motors with different performances.

Servo motor: fast, stable, high load and stable performance; The processed products have smooth edges and fast cutting speed; High price, applicable to industries and products with high processing requirements.

5. Machine tool

Fiber laser cutting machine requires high stability of the machine tool. High precision and high stability of the machine tool is conducive to improving the accuracy of laser cutting. At present, the mainstream machine tools in the market are gantry type, cantilever type, beam type, etc. Different machine tools have different functions. For example, beam type machine tools are mainly used for material cutting by large manufacturers, and there are also models used in specific fields, such as three-dimensional optical fiber laser cutting, mainly used in the automotive industry.

6. Laser lens

Laser lenses are the most widely used in the whole fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, including full reflective lenses, semi reflective lenses, focusing lenses, etc.

The quality of the lens directly affects the output power of the laser, as well as the performance of the whole machine. Similarly, lenses are also divided into domestic lenses and imported lenses. The service life and cutting effect of domestic lenses are not as good as those of imported lenses, but their prices are far cheaper than those of imported lenses.
