At present, there are many manufacturers of laser cutting machines. Although the equipment they produce is called fiber laser cutting machines, just like cars, the processing efficiency and effect of different equipment inside will vary greatly. For fiber laser cutting machines, the six core accessories must be taken into consideration when purchasing. When purchasing a laser cutting machine, you must look at these six core accessories:

1. Fiber laser

The laser is the "power source" with laser equipment as the core. Like the automobile engine, it is also the most expensive part of the fiber laser cutting machine. At present, the fiber laser brands on the market include IPG, Ruike, Chuangxin and so on. With the development of technology, domestic laser brands such as Ruike have also emerged and 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 a long supply cycle, resulting in high prices of high-power fiber laser cutting machines. The emergence of a hundred flowers blooming situation for Chinese fiber laser manufacturers has broken the monopoly of foreign enterprises in the laser field, and has directly lowered the price of imported products.

2. Laser cutting head

The laser cutting head is the laser output device of the fiber laser cutting machine, which is composed of nozzle, focusing lens and 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 fiber laser cutting machine. It 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. At present, the commonly used ones are Beifu CNC system and PA CNC system.

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 processing effect and production efficiency of the product. At present, the commonly used motors include stepper motor and servo motor. According to the industry type and product type of the processing object, appropriate electric machines are configured.

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

Servo motor: fast, smooth, high load, stable performance; The edge of the processed product is smooth and the cutting speed is fast; High price, suitable for industries and products with high processing requirements.

5. Machine tool

The fiber laser cutting machine requires very high stability of the machine tool. The machine tool with high accuracy 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, and there are also models used in specific fields, such as three-dimensional fiber laser cutting, mainly used in the automotive industry.

6. Laser lens

Laser lenses are widely used in the whole optical fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, such as full-reflection lenses, semi-reflection 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 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.
