CNC laser engraver for metal    processing technology has been widely used in many fields such as machinery industry, electronic industry, national defense and people's life. What are the main factors that affect the processing of CNC laser engraving machines, and which factors affect the processing of laser engraving machines?

1. The influence of output power and irradiation time

The laser output power is large and the irradiation time is long, and the laser energy obtained by the workpiece is large. When the focus is fixed on the surface of the workpiece, the greater the output laser energy, the larger and deeper the engraved pit, and the smaller the taper.

2. The influence of focal length and divergence angle

A laser beam with a small divergence angle can obtain a smaller spot and a higher power density on the focal plane after passing through a focusing objective lens with a short focal length. The smaller the spot diameter on the focal plane, the finer the product can be engraved.

3. The influence of the number of irradiation

With one laser irradiation, the depth of processing is about five times the width of the groove, and the taper is large. If the laser is used multiple times, not only the depth can be greatly increased, the taper can be reduced, but the width is almost unchanged.

4. The influence of workpiece material

Due to the different energy absorption spectra of various workpiece materials, it is impossible to absorb all the laser energy collected on the workpiece through the lens, and a considerable part of the energy is reflected or projected and lost. depends on the laser wavelength.
