Laser engraving is essentially material removal, and the entire process of a laser is only tens of microns deep. Therefore, the entire process of material removal is relatively slow. Currently, the guaranteed removal speed is calculated per cubic millimeter, and the high removal efficiency is determined by average power management. high quality portable fume extractor

In addition to high-quality laser engraving and high-efficiency material removal, the most important thing is to adopt improved processing solutions. Since grating ruler scanners generally cause furrows, there are difficulties in removing low depth and residual surface roughness. Therefore, unless it is an engraving requirement that is not high, it is generally not recommended to use this kind of processing technology. high quality portable welding fume extractor

The principle of PCB laser engraving is relatively simple. A single pulse of the laser acting on the material causes the material to melt, resulting in a molten pool. After ensuring a certain calorific value, the surface of the material vaporizes, causing reaction pressure on the solution, causing the solution to erupt. This is the actual system of laser engraving to remove the material. Everyone may have some misunderstandings about laser engraving. For example, the higher the mechanical energy of a single pulse, the greater the material removed; the higher the maximum power and the smaller the PWM duty cycle, the better the quality of laser engraving. In fact, the entire process of laser engraving is extremely complicated, and there is currently no clear processing plan that can guarantee the engraving quality.

Since the engraving quality and the material removal rate are mutually restricted, no matter from which aspect, customers should improve the selection of single pulse characteristics, photoelectric devices and basic parameters of processing/scanning machines to ensure processing quality and high processing efficiency. A reasonable and effective balance. high quality single arm laser fume extraction systems
