How to choose the air compressor for 2000w fiber laser machine for metal cutting?

2000w fiber laser machine for metal cutting is the laser emitted from the laser, through the optical path system, focused into high power density laser beam. Laser cutting machine work requires a gas source as a power source, and is the pressure of the gas source, the pressure generally needs 10 to 16 kg, laser beam irradiation to the workpiece surface, so that the workpiece reaches the melting point or boiling point, and the high pressure gas coaxial with the beam will melt or vaporize the metal blown away.

Features of laser cutting machine

1. Fast cutting speed, smooth incision, no burr;

2. Narrow cutting, small deformation, cutting surface material does not harden;

3. High machining accuracy and good repeatability;

4. Nc programming is simple, processing range is wide, no need to open the die, economic time saving;


Type of auxiliary air source

1. Nitrogen: generally processed precious metals or very high processing requirements as an auxiliary gas source;

2 oxygen: the strong oxidation of high purity oxygen, the cutting surface will be black, hardness increase, commonly known as "coke";

3. Compressed air: processing range is wide, air itself exists in the atmosphere contains about 20% oxygen, so it can make up for the lack of oxygen and nitrogen to a certain extent.


Cost of gas source

Because the cost of nitrogen and oxygen is higher than that of compressed air, and the price of nitrogen and oxygen increases year by year, the use of air as cutting auxiliary gas can greatly reduce the cost of production, about half.

The role of high pressure air source

1. Cooling prevents hardening of materials, that is, by heat treatment;

2. Air pressure will cut molten metal slag blowing off, prevent dust blocking laser nozzle, protect and extend its service life;


Laser cutting machine for compressed air source requirements

Laser cutting machine for compressed gas source requirements are relatively high, the requirements of the gas source can not contain water and oil, general users with four filter, or even five filter, the purpose is to better protect the service life of laser cutting machine. If the air source entering the cutting head contains water and oil, it will cause fogging of the protective lens in a short time, affecting the cutting quality. At this time, if the protective lens is not replaced in time, the internal temperature of the cutting head may rise under the irradiation of high power beam, resulting in damage to the internal mirror group.

Post-processing installation and layout

1. Compressor and laser cutting machine close distance, cold and dry machine filter connected in turn;

2. The compressor and the laser cutting machine are far away, and two filters are installed in the terminal to deal with the residual water and oil in the long-distance pipeline;
