How to choose laser cutting machine air compressor?

          The laser cutting machine focuses the laser light emitted from the laser device into a high power density laser beam through the optical path system.  The laser beam of the CNC cutting machine irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. With the movement of the relative position of the beam and the workpiece, the material finally forms a slit,so as to achieve the purpose of cutting.

When laser cutting workpieces, the main factors affecting cutting accuracy and surface quality

Compressed air quality

Workpiece material quality

Laser cutting equipment performance and quality

          The quality of the profiles used to process workpieces is poor, and there are defects such as cracks, sand inclusions, and pores, which will inevitably increase the scrap rate of the final molded parts; If the quality of laser cutting equipment is not up to standard, it will also increase the scrap rate and affect the stability of the overall production.

Analysis of Laser Cutting Protective Gas

Nitrogen

       Nitrogen is an inert gas, which can protect the laser cutting surface very well, but because it isolates oxygen, the processing efficiency is reduced, and the cost of nitrogen is relatively high, so unless processing precious metals or very high processing requirements, CNC cutting machines are generally very expensive.  Bottled nitrogen is rarely chosen as an auxiliary gas for routine processing.

oxygen

   It can support combustion, but due to the strong oxidizing properties of high-purity oxygen, the cut surface will turn black and the hardness will increase, which is commonly known as "scorch".  Therefore, air with an oxygen-nitrogen ratio of about "30-70" has become the best choice for laser cutting in general processing.

compressed air

   Since the compressed air mainly acts on the lens of the laser cutting machine head, if it contains oil or water, it will inevitably pollute the lens, and seriously reflect the laser, causing the calibration mirror, focusing mirror and laser head to burn out.    Therefore, the quality of compressed air is also an important factor affecting the quality of laser cutting final molded parts.
