The working principle of DADI CNC laser tube cutting machine is mainly based on the high energy density and precise control of laser beam. The following is a detailed description of the working principle:
1. Laser generation and transmission
Laser source: The core component of the laser tube cutting machine is the laser, which is responsible for generating high-energy and stable laser beams. After being excited by electrical energy, the gas, solid or semiconductor material inside the laser generates photons and is continuously amplified by the reflector of the resonant cavity, eventually forming a beam of high-energy and high-density laser.
Transmission system: The generated laser beam is transmitted to the cutting head through an optical system such as an optical fiber or a lens group. In this process, the laser beam may be adjusted and focused by the reflector and lens to ensure that the laser beam can be accurately and stably transmitted to the cutting area.
2. Focusing and cutting
Focusing system: The cutting head is an important executive component of the DADI CNC laser tube cutting machinehttps://www.dadilaser.com/Laser-Tube-Cutting-Machine/122.html. It is responsible for focusing the laser beam onto a very small spot to increase the energy density of the laser. Through a high-precision lens system and reflector, the laser beam is focused onto a spot with a diameter of only tens of microns, which can instantly melt or even vaporize metal materials.
Cutting process: When the high-energy laser beam irradiates the surface of the tube, the material in the irradiated area quickly melts, vaporizes or reaches the ignition point. At the same time, a high-speed airflow (such as nitrogen, oxygen, etc.) coaxial with the beam blows away the molten material, thereby achieving the cutting of the tube. The movement trajectory of the laser beam is precisely controlled by a computer, and it can be cut according to the preset graphics.
3. Control system and operation
Control system: The control system of the DADI CNC laser tube cutting machine consists of computer software and motion controller. The computer software is responsible for designing and editing the cutting graphics and converting them into instructions for laser cutting. The motion controller controls the movement of the laser head on the tube to achieve the predetermined cutting path and speed. By adjusting the cutting parameters (such as laser power, focus position, cutting speed, and auxiliary gas injection, etc.), the accuracy and stability of the cutting process can be ensured.
Operation process: During the operation, the tube to be cut first needs to be placed on the cutting table and fixed with a clamp to ensure stability and accuracy. Then, the laser cutting process is started through the control system. The laser beam moves on the tube, and the metal material is heated and evaporated by the high-temperature and high-energy laser beam to achieve cutting. After the cutting is completed, the laser stops and the cutting head returns to the initial position. The operator removes the cut tube and cleans the residual slag in the cutting area.
In summary, the working principle of DADI CNC laser tube cutting machinehttps://www.dadilaser.com/Laser-Tube-Cutting-Machine/122.html is a comprehensive embodiment of optical, mechanical, electrical and computer technology. It uses a high-energy-density laser beam to accurately cut the tube, with the advantages of fast cutting speed, high precision and smooth incision, and has been widely used in the field of metal processing.
