Some consideration before purchase metal sheet cnc fiber laser cutting machine

Reading Time: 5 minutes

For metal sheet cutting below 10mm, users are more inclined to choose fiber metal fiber laser cutting machine. Because it not only has good beam quality, fast cutting speed, high cutting precision, and low maintenance costs, it is the most ideal equipment for cutting metal sheets. However, when many customers purchase fiber metal fiber laser cutting machine, due to lack of professional knowledge, the machine they bought is not very ideal.
In fact, for the domestic fiber metal fiber laser cutting machine, there is no need to care about its core technology, more attention should be paid to its accessories. A good metal fiber laser cutting machine has a very high configuration and a much more stable performance. So, what accessories should customers pay attention to when purchasing fiber metal fiber laser cutting machine?

Fiber laser: At present, the popular fiber laser brands in the market are Rofin and TRUMPF, but the self-developed medium and small power fiber lasers are also good. Users can decide whether to choose an imported brand or a domestic brand according to their own budget.

Metal fiber laser cutting machine cutting head: There are two popular cutting heads on the market, one is the lasermach cutting head from the United States, and the other is the German Precitec cutting head. The Precitec cutting head can automatically adjust the focal length to ensure the cutting effect of the whole board, avoiding the material scrap caused by the problem of focal length change when the material is uneven.

Servo motor: High-quality servo motor can effectively ensure the cutting accuracy, positioning speed and repeat positioning accuracy of the metal fiber laser cutting machine.


Chiller: When purchasing a metal fiber laser cutting machine, it is recommended that customers choose a chiller with advanced functions such as input and output control equipment switches, cooling water flow, and high and low temperature alarms, because the performance of such chillers is more stable.
Gas system: The gas supply system of the fiber metal fiber laser cutting machine mainly includes gas source, filter device and pipeline. Among them, there are two kinds of air sources: bottled air and compressed air.
Host: The bed, beam, worktable, and Z-axis system of the metal fiber laser cutting machine are collectively referred to as the host. When the metal fiber laser cutting machine performs cutting, first put the workpiece on the bed, and then use the servo motor to drive the beam to control the movement of the Z axis. The user can adjust the parameters according to their own needs. The bed of pure steel plate structure is more advantageous because it is not easy to shake.

Control system: 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. At present, the more common systems are XP and 2000 systems, and there is little difference between them.
Regulated power supply: connected between the laser, CNC machine tool and the power supply system. It mainly plays a role in preventing interference from external power grids.
Ventilation dust collector: extract the smoke and dust generated during processing, and carry out filtering treatment, so that the exhaust gas emission meets the environmental protection standards.
Below we introduce the function and structure of the fiber metal fiber laser cutting machine.

  1. Air cooling dryer, filter: used to supply clean and dry air to the light generator and beam path to keep the path and reflector working normally.

2. Outer optical path: Refractive reflector, used to guide the laser in the required direction. In order to prevent the beam path from malfunctioning, all mirrors must be protected by a protective cover, and a clean positive pressure protective gas should be introduced to protect the lens from contamination.

3.Numerical control system: control the fiber metal fiber laser cutting machine machine tool to realize the movement of X, Y, Z axis, and also control the output power of the laser.

4.The main machine part of the machine tool: the machine tool part of the metal fiber metal fiber laser cutting machine, the mechanical part that realizes the movement of the X, Y, and Z axes, including the cutting work platform. It is used to place the workpiece to be cut and can move it correctly and accurately according to the control program, usually driven by a servo motor.

5.Laser generator: a device that generates a laser light source.

6.Exhaust dust collector: extract the smoke and dust generated during processing, and filter it to make the exhaust gas meet environmental protection standards.

7.Slag discharging machine: The main function is to eliminate the leftovers and scraps generated during processing.

8.Operating table: used to control the working process of the entire cutting device.

9.Gas cylinders: including working medium gas cylinders and auxiliary gas cylinders for optical fiber metal fiber laser cutting machines, which are used to supplement the industrial gas for laser oscillation and supply auxiliary gas for the cutting head.

10.Water chiller: used to cool the laser generator. A laser is a device that converts electrical energy into light energy. For example, the conversion rate of a CO2 gas laser is generally 20%, and the remaining energy is converted into heat. The cooling water takes away the excess heat to keep the laser generator working normally. The chiller also cools the external light path reflector and focusing mirror of the machine tool to ensure stable beam transmission quality and effectively prevent the lens from being deformed or broken due to excessive temperature.

11.Regulated power supply: connected between the laser, CNC fiber metal fiber laser cutting machine machine tool and the power supply system. It mainly plays a role in preventing interference from external power grids.

12.Air compressor, air storage tank: provide and store compressed air.

13.Cutting head: It mainly includes parts such as cavity, focusing lens holder, focusing lens, capacitive sensor and auxiliary gas nozzle. The cutting head driving device is used to drive the cutting head to move along the Z axis according to the program, and is composed of a servo motor and a screw or gear and other transmission parts.

Through the above introduction, everyone has also understood the advantages of fiber metal fiber laser cutting machine. By understanding the advantages of fiber metal fiber laser cutting machine, we will gradually pay more and more attention to the development of fiber metal fiber laser cutting machine. The application of metal fiber laser cutting machine should be more confident.
