China Laser Cutting Machine For Aluminium Factory

The control system of the Fiber Laser Cutting Machine employs advanced CNC (computer numerical control) technology, featuring an intuitive and user-friendly interface that supports multiple file formats such as DXF, DWG, AI, and PLT. Users can effortlessly import design drawings into the control system and monitor and adjust them in real-time. The CNC system also includes automatic typesetting and path optimization functions, which further enhance material utilization and cutting efficiency. Fiber Laser Cutting Machines exhibit extensive material compatibility, capable of cutting various metal materials, including stainless steel, carbon steel, aluminum, copper, and brass. Fiber laser cutting machine manufacturers can also handle materials of different thicknesses, from thin sheets to thick plates.

In addition to its general capabilities, the Fiber Laser Cutting Machine is highly effective as a laser cutting machine for aluminium. This makes it ideal for industries requiring precise and efficient cutting of aluminum, such as aerospace, automotive, and electronics manufacturing.Due to the shorter wavelength of the fiber laser, the beam is more concentrated, resulting in faster cutting speeds, smoother incisions, and burr-free edges, thereby reducing the need for subsequent processing. In terms of environmental protection and safety, Fiber Laser Cutting Machines perform exceptionally well. The laser cutting process generates minimal waste, and many machines are equipped with smoke and exhaust gas treatment systems to mitigate environmental impact. Additionally, Fiber Laser Cutting Machines are equipped with various safety features, such as protective covers, emergency stop buttons, and laser safety interlocks, ensuring operator safety.

Working Principle of Fiber Laser Cutting Machine

1. Laser Generation: The Fiber Laser Cutting Machine utilizes a specialized laser—fiber laser—to generate a high-power laser beam. This laser excites the doped elements in the optical fiber through the light emitted by the pump diode, producing the laser.
2. Laser Transmission: The generated laser beam is transmitted to the cutting head via optical fiber. The optical fiber maintains good beam quality and anti-interference capability, ensuring the stability and accuracy of the laser during transmission.
3. Laser Focusing: Upon reaching the cutting head, the laser beam is focused to a very small point using a focusing lens or a reflector system. The diameter of this focal point can be extremely small, enabling high-precision cutting.
4. Material Cutting: The focused laser beam is directed onto the surface of the material to be cut. The material absorbs the laser energy, converting it into heat, causing the material to melt, vaporize, or evaporate directly. This process is non-contact, hence referred to as non-contact cutting.
5. CNC System Control: The entire cutting process is governed by a computer numerical control (CNC) system. The operator inputs the cutting pattern and parameters through the software, and the CNC system controls the laser head’s movement path and the laser’s operation to achieve precise cutting.
6. Assist Gas: During the cutting process, assist gas (such as nitrogen, oxygen, or air) is typically used to help remove the melted or vaporized material while protecting the cut edge from oxidation or other chemical reactions.
7. Cutting Completion: As the laser head moves along the predetermined path, the laser beam creates a continuous cutting line on the material, ultimately completing the cutting process. The cut workpiece can be directly used for subsequent processing or assembly.
