Laser cutting machine basics These six core components

In the metal processing, fiber laser cutting machine has gradually replaced the traditional technology with its advantages, and has become a weapon in the metal processing industry.
But even if it is also calle fiber laser cutting machine, the processing efficiency and effect of different equipment in the inside will be very different. For fiber laser cutting machine, the six core parts must be seen when purchasing.

1. Fiber laser

Lasers are the „power source“ of the core of laser equipment, just like automotive engines, and are expensive components in 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 Ruike and Chuangxin 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, 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 leading 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, and the cutting effect can improve by software control. Currently used Beckhoff CNC system, PA numerical control system, Falyan card 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 configure according to the industry type and product type of the processing object. Suitable motor.
Firstly, Stepper motor: It has fast starting speed and sensitive response, and is suitable for engraving and cutting processing. The price is lower. Stepper motors have many brands and different performances.
Secondly, servo motor: fast moving speed, smooth movement, high load, stable performance; smooth edge processing and fast cutting speed; high price, suitable for industries and products with high processing requirements.

 5, machine Bed

Mostly fiber laser cutting machines have very high requirements for machine tool stability. So 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 use 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 use in the whole fiber laser cutting equipment. Many optical devices contain laser lenses. Different lenses have different functions, such as full-reverse lenses, semi-reverse lenses, and focusing lenses.
In general,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 divide 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.
