In metal processing, the fiber laser cutting machine has gradually replaced the traditional technology with its high efficiency and high quality and has become a weapon in the metal processing industry.
But even if it is also called fiber laser cutting machine, the processing efficiency and effect of different equipment in the inside will be very different. For the fiber laser cutting machine, the six core parts must be seen when purchasing.
1. Fiber laser
Lasers are the most "power source" of laser equipment, just like the car engine, and the most expensive part of fiber laser cutting machines. At present, the imported brands of fiber lasers in the market include German IPG, ROFIN, British SPI, American coherent, etc. With the development of technology, domestic laser brands such as Raycus and JPT have also emerged, and they are 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 long lead times, resulting in high prices for high-power fiber laser cutting machines. The emergence of China's fiber laser manufacturers has broken the monopoly of foreign companies in the field of lasers, and directly lowered the price of imported products.
2, the cutting head
The cutting head is a laser output device of a fiber laser cutting machine, which is composed of a nozzle, a focusing lens, and a focus tracking system. The cutting head of the laser cutting machine will walk according to the set cutting trajectory, 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 operating performance of the fiber laser cutting machine. Through the precise control of the software, the accuracy and cutting effect can be effectively improved. Currently used Beckhoff CNC system, Cypcut CNC system, etc.
4, the motor
The motor of the laser cutting machine is the core component of the motion system. The performance of the motor directly affects the processing effect and production efficiency of the product. At present, the commonly used motors include stepping motor and servo motor, which are configured according to the industry type and product type of the processing object. The most suitable motor.
The starting speed is fast and the reaction is sensitive, which is suitable for engraving and cutting processing. The price is lower. Stepper motors have many brands and different performances.
The movement speed is fast, the movement is stable, the load is high, the performance is stable; the processed product has smooth edges and fast cutting
speed; the price is high, and it is suitable for industries and products with high processing requirements.
5, machine tools
Fiber laser cutting machines have very high requirements for machine tool stability. High precision and high stability machine tools help to improve the precision of laser cutting. At present, mainstream machine tools on the market include gantry, cantilever, beam, etc. Different machine tools have different functions. For example, beam type machine tools are mainly used for material cutting by large manufacturers, and also 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, such as full-reflex lenses, semi-reverse lenses, and focusing lenses.
The quality of the lens directly affects the output power of the laser, which also affects the performance of the whole machine. The same lens is also divided into domestic and imported. The life and cutting effect of domestic lenses are not as good as imported lenses, but the price is far cheaper to import lenses.
