Laser marking is the most widely used laser processing technology. Its mechanism is that the surface material is melted and vaporized or the color changes instantaneously through the local irradiation of the laser to the workpiece, thereby leaving permanent text, patterns, etc. mark. Laser marking will not corrode the surface of the workpiece, and will not produce stress after processing and affect the original accuracy. Therefore, laser marking technology has a wide range of applications. The principle and system composition of marking different materials are basically the same. Experiments to find out the most suitable parameter settings for each material can complete the laser marking of different materials. fume extractor for 50w co2 laser

The laser marking system consists of lasers (mostly using Nd:YAG lasers), galvanometer part (drive signal to control galvanometer deflection so that the laser output point scans graphics and text), and numerical control part (to complete the editing, format conversion, and export of scanned graphics and text) Information) and power control part (including laser power supply, acousto-optic power supply, water cooling system control) four parts. fume extractor arm 50mm

The laser marking process is to first edit the required graphic information through computer software, convert it into a format that can be recognized by the marking software, and import the galvanometer servo control card into a signal that can be recognized by the galvanometer. The transmission of these electrical signals to the scanning galvanometer will cause the galvanometer to swing in the X and Y directions, so that the output point will scan out the graphic label information. At the same time, under the control of the signal, the acousto-optic power supply causes the acousto-optic Q switch to generate the required frequency modulation signal, so that the continuous laser is modulated into discontinuous laser pulses, and the scanned graphic mark information can be displayed on the processed workpiece. superior.

With the birth of more and more laser marking companies, there is more and more worry about the smoke and dust pollution generated during the processing. One is the worry about the health of the operators, and the other is the strict inspection by the environmental assessment department. Many laser companies are looking for more suitable laser smoke purifiers in the market to solve the above-mentioned troubles.
