Laser cutting machine is a precision tool used in various industries. It relies on laser beam to accurately cut materials. In modern manufacturing, laser cutting machines are becoming increasingly important due to their accuracy and efficiency. This article will comprehensively analyze the working principle of laser cutting machines.
1.Basic Components of a Laser Cutting Machine
At the heart of a metal laser cutting machine is the laser generator. This is where the laser beam is created. The type of laser generator, such as a fiber laser or a gas laser, determines the characteristics of the laser beam. The optical system then directs and focuses the laser beam onto the workpiece. The mechanical system consists of a worktable, motor, and other components. These components move the workpiece or laser head to cut in a precise pattern. At the same time, the control system supervises the whole operation, coordinating the laser generator, optical system, and mechanical system.
2.Working Principle of a Laser Cutter
The working principle of a laser cutting machine is quite straightforward. The laser beam, generated by the laser generator, is transmitted through the optical system and focused onto a tiny spot on the workpiece. As the laser beam strikes the material, it heats up the area to a high temperature, causing the material to melt, vaporize, or burn away. The control system ensures that the laser beam moves along a predefined path, cutting through the material in a precise manner. The mechanical system moves the workpiece or the laser head to follow this path, achieving the desired cutting result.
3.Characteristics of Laser Cutting Technology
High precision. The focused laser beam can achieve cutting with minimal deviation, ensuring accurate results. High efficiency. The laser beam can quickly heat and cut materials, greatly reducing processing time.
Environmentally friendly and energy-saving. It does not produce harmful emissions. It consumes less energy than traditional cutting methods.
4.Applications of Fiber Laser Cutting Machines in Practice
Laser cutting machines have a wide range of applications in various industries.
