What is the principle of a metal cutting machine?

Release time:

2020-11-08

The metal cutting machine, also known as the metal laser cutting machine, generally projects a laser onto the surface of the metal. The energy released by the laser can melt and evaporate the metal workpiece, ultimately achieving the purpose of cutting or engraving. It features fast cutting speed and high precision, and the cutting is not limited by patterns; any pattern can be cut. Additionally, it has characteristics such as material savings and low processing costs.

The principle of the metal cutting machine:
The metal laser cutting machine uses a high-energy output laser beam generated by a xenon gas, focused on the surface of the metal workpiece, causing the area illuminated by the laser beam to melt and vaporize. Then, the position of the laser beam is controlled by a computer to complete the entire cutting action, which is fundamentally different from machine tool processing.
During the cutting process, the metal laser cutting machine will add auxiliary gases that are compatible with the material being cut. For example, when cutting steel, oxygen is added as an auxiliary gas to participate in the exothermic chemical reaction with the metal.
Metal cutting machines can be classified based on the power of the laser in the equipment into high-power metal cutting machines, fiber metal sheet cutting machines, and metal engraving and cutting integrated machines, etc.
As a new type of tool, the metal cutting machine is increasingly favored by more industries, and the industries it can be applied to are also growing, such as the metal cutting industry, textile fabric cutting industry, laser marking industry, laser engraving industry, and so on.

How to choose a fiber optic cutting machine? These five steps are essential.

In recent years, fiber laser cutting technology has been widely used in the processing industries such as sheet metal and handicrafts, with applications in both metal and non-metal cutting becoming increasingly common. The technology of fiber laser cutting machines has matured significantly, holding a certain market share in the cutting industry. However, many users still face various issues when it comes to purchasing a suitable fiber cutting machine. So, how to choose the right fiber cutting machine? The following five steps introduced by the editor are essential!

The technology of laser cutting machines has broad development prospects and huge application space in the domestic market.

The laser cutting machine focuses the laser emitted by the laser source into a high power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach its melting point or boiling point, while blowing away the high-pressure gas of the melted or vaporized metal that is coaxial with the laser beam.
