Radium cavving principle, namely the laser processing principle:

1, the use of laser emission of high intensity laser beam focus in place, and let the material oxidation and carry on the processing.

2, the effect of playing mark is through the surface physical evaporation show deep material, or through the light energy cause surface physical chemistry physical change out of the mark, or through the light burned part substances, and scribing trace, or through the light burned part material, show required etching graphics, text.

Quality features:
