How much do you know about laser cutting?

What is the principle of laser cutting machine?

Laser cutting uses a focused high-power density laser beam to irradiate the workpiece, causing the irradiated material to quickly melt, vaporize, ablate or reach the ignition point. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam to cut the workpiece.

What are the components of a laser cutting machine?

Laser cutting machine is a laser cutting equipment used to cut and process metal materials. During operation, laser cutting machines have the characteristics of fast cutting speed and high cutting accuracy, so they are widely used in different industries. So, what parts does a laser cutting machine consist of ?

1. Mainboard: The laser cutting machine’s bed, beam, workbench, Z-axis system, gas control system, electronic control system, transmission system, protective shell, safety system, etc. are collectively referred to as the mainboard. When the laser cutting machine is cutting, the workpiece is first placed on the workbench, and then the servo motor is used to drive the beam and control the movement of the Z-axis. The user can adjust the parameters according to their own needs.

2. Laser: It is the core component of the laser cutting machine and the “power source” for the laser cutting machine to achieve cutting operations. Compared with other types of lasers, the fiber laser used by Hugong laser cutting machine has the advantages of higher photoelectric efficiency, longer service life, less maintenance, and lower cost.

3. Cutting head: The cutting head of a laser cutting machine is a laser output device, which consists of a nozzle, a focusing lens and a focus tracking system. The cutting head of the laser cutting machine will move according to the set cutting trajectory, but under different materials, different thicknesses, and different cutting methods, the focus position of the laser cutting head is automatically controlled by the CNC.

4. Water cooler: The water cooler is the cooling device of the fiber laser cutting machine. It can quickly and efficiently cool the laser, spindle and other devices. Today’s chillers include advanced functions such as input and output control equipment switches, cooling water flow, and high and low temperature alarms, making their performance more stable.

5. Servo motor: Servo motor refers to the engine that controls the operation of mechanical components in the servo system. Servo motors can control speed and position accuracy very accurately, and can convert control signals into speed and position to drive control objects. High-quality servo motors can effectively ensure the cutting accuracy, positioning speed and repeat positioning accuracy of the laser cutting machine.

6. Air supply system: The air supply system of the laser cutting machine mainly includes air source, filter device and pipeline. The gas sources include bottled gas, liquefied gas, and compressed air.

7. 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 fiber laser.

Therefore, the above parts are important components of the laser cutting machine. Moreover, due to different models and brands of laser cutting machines, there are still differences in the components that make up the cutting machine. Therefore, when purchasing a laser cutting machine, you still need to combine Get an in-depth understanding of the brand, reputation, actual operating scenarios and uses of laser cutting machines, and then choose the laser cutting machine that suits you based on the company’s production purposes and usage scenarios.
