Cutting of thick plexiglass material for plastic machine production

Thick material cutting (10-20mm) plexiglass above 10mm generally uses a 75mm focusing mirror, plexiglass above 25mm uses a 100mm focusing mirror, and the deepest can cut 32mm plexiglass. 10mm plexiglass cutting: the cutting speed is generally 0.08-0.12 m/min, and the light intensity is 60-70%. The most stable when the light intensity is 60%, the air leakage jet cup adjusts the air flow and makes the edge smoother. Because the blowing is larger, the molten object is blown back to the plexiglass by the auxiliary high-pressure gas when cutting to form a non-smooth surface. Keep the wind as low as possible. Sometimes, customers need to add paper or add film to cut, and the wind should not be too small at this time, otherwise it will catch fire. When cutting plexiglass, the speed and light intensity must be well matched. The slower the speed, the better the smoothness. It is best to use imported high-power lasers for plexiglass above 15mm. When engraving plexiglass, use a leaking air jet cup. Try not to engrave too deep. It is difficult to achieve the flatness of the bottom. The greater the gas, the effect of the engraving edge will be affected. The engraving should be finer and clearer, not too deep and stingy. What you need to pay attention to in engraving is the resolution setting. If you output BMP format, the resolution should generally be above 600dpi. At this time, the speed is 8-18 m/min, and the light intensity is 20%-30%. When cleaning, turn off the blow to make the bottom smoother.
