Principle And Application Of Metal Laser Cutting Machine
Introduction
With the continuous development of industrial technology, the metal processing industry has higher and higher requirements for processing accuracy and efficiency. As an advanced cutting equipment, metal laser cutting machine has gradually become an important tool in the field of metal processing due to its advantages such as high efficiency, precision and flexibility. This article will discuss in detail the working principle, main components, application fields and future development trends of metal laser cutting machine.
Working Principle of Metal Laser Cutting Machine
Metal laser cutting machine mainly uses laser beam as cutting tool, and heats, melts or vaporizes metal materials through high energy density laser beam to achieve the purpose of cutting. Its basic working process is as follows:
Laser generation: Metal laser cutting machine is usually equipped with laser generator inside, and different types of laser cutting machines use different laser sources, such as CO2 laser, fiber laser, etc. These laser sources are excited to generate laser through electrical energy or other means.
Laser transmission: The generated laser is transmitted to the cutting head through optical fiber or reflector. Fiber laser cutting machine uses optical fiber as laser transmission medium. Compared with traditional CO2 laser cutting machine, it has higher conversion efficiency and lower maintenance cost.
Focused cutting: The laser is focused through the lens of the cutting head to form a very small spot with extremely high energy density, which can quickly heat and melt the metal material. During the cutting process, auxiliary gas (such as oxygen, nitrogen or air) will be ejected to help discharge the molten metal and improve the cutting quality.
Cutting movement: The laser cutting machine is generally equipped with a CNC system that can accurately control the movement trajectory of the cutting head on the workpiece. Combined with CAD/CAM software, users can easily generate cutting programs according to design drawings to achieve cutting of complex shapes.
Main components of metal laser cutting machine
The metal laser cutting machine consists of several key components, each of which plays an important role in the overall work:
Laser generator: The core component responsible for generating the laser beam, which affects the cutting effect and speed.
Cutting head: Used to focus the laser and guide the laser beam to irradiate the workpiece, usually equipped with autofocus function to adapt to materials of different thicknesses.
Motion platform: The workbench that carries the workpiece is equipped with a precision servo motor and guide rail system to ensure the accurate movement of the cutting head.
CNC system: responsible for the preparation and execution of cutting programs, providing a human-computer interaction interface to facilitate operators to set up and monitor.
Cooling system: A large amount of heat is generated during the laser cutting process. The cooling system is used to protect the laser and cutting head and extend the life of the equipment.
Auxiliary gas system: Provides necessary gas for cutting, which not only helps to discharge molten metal, but also improves cutting quality.
