| Laser cutting plexiglass with speed, high precision, accurate positioning and other obvious advantages . And can be gifts, panel lens chassis , model toys , advertising light box signs show supplies , packaging and other industries have irreplaceable application . Laser cutting with the traditional mechanical cutting method , this new approach has several important advantages. First, it is a step to complete , dry process . Edge smooth and tidy , no subsequent cleaning and polishing . And the laser light caused by the separation process to produce high strength , natural tempering edges, no tiny cracks. Using this method to avoid the unexpected cracks and broken , reducing the defect rate , improve the yield . Precisely because the cracks are drawn along the traces of the laser beam , the laser cut separation can be a result of a curve drawn very precise patterns. In fact, we have done experiments also proved either straight or curve , laser cutting can be continuously and accurately complete the setup pattern repeatability of up to +50 μm. So the laser can curve and 3D graphics precision cutting . Cutting speed limit has three factors: the thickness of the glass , the thermal expansion coefficient, and the laser output power . In this test , we use the output power of 150W CO2 laser cutting thickness of 1. 1mm glass , straight cuts , speed of 500mm / s . As a comparison , the hard metal wheel cutting the same thickness of glass at speeds up to the same 1500mm / s. However , even in applications where speed is important , this difference will also be brought about by laser cutting economic and quality advantages of offset . We believe that further process optimization and use of higher laser output power for cutting processing speed will be easily increased by 2 to 3 times. |
