In metal processing, optical fiber laser cutting machine, with its advantages of high efficiency and high quality, has gradually replaced the traditional process and become a professional weapon in metal processing.
But even if the same is called optical fiber laser cutting machine, the processing power and effect of different equipment inside will be very different. For optical fiber laser cutting machine, the six core accessories must be considered when purchasing.
1. Fiber laser
Laser is the core “power source” of laser equipment, just like the car engine, it is also the most expensive part of the fiber laser cutting machine. Now the imported brands of fiber lasers on the market include IPG, ROFIN, SPI in the UK, and Coherent in the US
With the development, domestic laser brands such as Ruike and Chuangxin are also 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 schools of thought contending among Chinese fiber laser manufacturers has broken the monopoly of foreign enterprises in the laser field, and also directly
Lower 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 is high under different materials, different thicknesses and different cutting methods
Degrees need conditioning and manipulation.
3. CNC system
The control system is the leading operation system of the fiber laser cutting machine. The first thing is to control the machine tool to achieve X, Y, Z axis movement, and also control the output power of the laser. Its quality determines the stability of the operation function of the optical fiber laser cutting machine. Through the accurate control of the software
To improve accuracy and cutting effect. Now commonly used Beckhoff CNC system, PA CNC system, Farianka system, etc.
4. Motor
The motor of the laser cutting machine is the core component of the motion system. The function of the motor directly affects the product processing effect and output power. Now the commonly used motors include stepping motors and servo motors. According to the occupational type and product type of the processing object, the most suitable motor is equipped
Stepping motor: fast starting speed, flexible response, suitable for carving and cutting with low requirements. The price is low. There are many brands of stepping motors with different functions.
Servo motor: fast movement, stable movement, high load and stable function; The edge of processed products is smooth and the cutting speed is fast; The high price is suitable for occupations and products with high processing requirements.
5. Machine tool
Fiber laser cutting machine requires very 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 effects. For example, beam type machine tools are mainly used
For material cutting of large manufacturers, there are also models for specific categories, such as 3D optical fiber laser cutting, mainly for car occupation.
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 effects, including full reflective lenses, semi reflective lenses, and focusing lenses.
The quality of the lens directly affects the output power of the laser, as well as the function of the whole machine. The same 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.
