In metal processing, fiber laser cutting machines have gradually replaced traditional craftsmanship with their advantages and become a weapon in the metal processing industry.
But even if they are all called fiber laser cutting machines, the processing efficiency and effects of different equipment inside will be very different. For fiber laser cutting machines, the six core accessories must be looked at when purchasing.
1. Fiber laser
Laser is the core "power source" of laser equipment, just like car engine, it is also an expensive component in fiber laser cutter. At present, the imported brands of fiber lasers on the market include German IPG, ROFIN, British SPI, American Coherent, etc. With the development of technology, domestic laser brands such as Ruike and Chuangxin 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, which consists of a nozzle, a focus lens and a focus tracking system. The cutting head 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, 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. Through software control, the cutting effect can be improved. Currently commonly used Beckhoff CNC system, PA CNC system, Farianka system, etc.
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. 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 motion, stable motion, 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
Fiber laser cutting machines have very high requirements for machine stability. 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 mostly used in the entire fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, such as all-reflection lenses, semi-reflection lenses, focusing lenses, and so on.
