In metal processing, with its advantages of high performance and high quality, the fiber laser cutting system has steadily replaced conventional technology and has become a sharp tool in the metal processing industry.
But even though they are all called fiber laser cutting devices, there would be very distinct processing efficiency and effects of different equipment within. The six core accessories must be looked at while buying fiber laser cutting machines.
1. Fiber laser source
Laser is the core "power source" of laser equipment and is also the most expensive component of the fiber laser cutting machine, much like the car engine. German IPG, ROFIN, British SPI, American Coherent, etc. are already amongst these imported brands of fiber lasers on the market. With the development of technology, domestic laser brands such as Max have also emerged, and are gradually recognized by the market for their high cost performance.
For a long time, lasers in our country have basically relied on imports, which are expensive and have a long supply cycle, resulting in high-power fiber laser cutting machines. The emergence of many Chinese fiber laser manufacturers has broken the monopoly of foreign companies in the field of lasers, and directly lowered the price of imported products.
2. Cutting head
The cutting head is the laser output device of the fiber laser cutting machine, which consists of a nozzle, a focus lens and a focus tracking system. The cutting head of the laser cutting machine will travel according to the set cutting track, 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 dominant operating system of the fiber laser cutting machine, which mainly controls the machine tool to realize the movement of the X, Y, and Z axes, and also controls the output power of the laser. Its quality determines the stability of the operation performance of the fiber laser cutting machine. Through the precise control of the software, the accuracy and cutting effect can be effectively improved.
The motor of the laser cutting machine is the core component of the motion system. The performance of the motor directly affects the effect of product processing and production efficiency. At present, the commonly used motors include stepper motors and servo motors. The configuration is based on the type of industry and product type of the processing object. The most suitable motor
Stepping motor: fast starting speed, sensitive response, suitable for engraving processing and cutting processing with low requirements. The price is lower. There are many brands of stepper motors with different performances.
Servo motor: fast movement, stable movement, high load, stable performance; smooth edges of processed products, fast cutting speed; high price, suitable for industries and products with high processing requirements.
5. Machine tools
The fiber laser cutting machine has very high requirements for the stability of the machine tool, and the machine tool with high precision and high stability is conducive to improving the accuracy of laser cutting. At present, the mainstream machine tools on the market include 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 of large manufacturers. There are also models for specific fields, such as three-dimensional fiber laser cutting. , Mainly used in the automotive industry.
6. Laser lens
Laser lenses are the most used in the entire fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, including all-reflection lenses, semi-reflection lenses, focusing lenses and so on.
The quality of the lens directly affects the output power of the laser, as well as the performance of the whole machine. Similarly, the lenses are also divided into domestic and imported lenses. The life span and cutting effect of domestic lenses are not as good as imported lenses, but their prices are far cheaper.
