Laser cutting plexiglass has obvious advantages such as fast speed, high precision, and accurate positioning. And it can be irreplaceable in craft gifts, panel lens cases, model toys, advertising light boxes, signboard display supplies, packaging boxes and other industries. Its advantages can be specifically divided into the following points:
(1) Good cutting effect: the incision does not need to be thrown by fire, it is very smooth, bright, no zigzag, and can cut acrylic thickness of 20mm at one time;
(2) Excellent performance of the whole machine: it can work continuously 24 hours a day without stopping the machine, and the original guide rail in Taiwan is accurate and durable;
(3) Good quality and long life of the laser tube: the best laser tube in the domestic machine not only has stable performance, but also has a long life (about 8~14 months), a power of 85W, and is used for half a year;
(4) Fast cutting speed: such as used to cut acrylic sheet with a thickness of 3mm.
This new method of laser cutting has several important advantages over traditional mechanical cutting methods. First of all, it is a dry process that can be completed in a single step. The edges are smooth and neat, and do not require subsequent cleaning and sanding. In addition, the laser-induced separation process produces high-intensity, naturally tempered edges with no microscopic cracks. With this method, unpredictable cracks and breakage are avoided, the rejection rate is reduced, and the yield is increased.

Curves Because a crack is a trace that is precisely drawn along the laser beam, the laser-induced separation can cut a very precise curve pattern. In fact, our experiments have proven that laser cutting can continuously and precisely complete the set pattern with a repeatability of up to +50 μm, regardless of whether it is a straight line or a curve. As a result, the laser can perform precise cutting of curves and three-dimensional patterns.
Cutting thickness and cutting speed of laser cutting There are three factors
that limit the cutting speed: the thickness of the glass, the coefficient of thermal expansion of the material, and the output power of the laser. In this test, we used a CO2 laser with an output power of 150W to cut at a thickness of 1. 1mm glass, straight cutting, speed of 500mm/sec. For comparison, a hard metal wheel can cut the same thickness of glass at a speed of up to 1500 mm/s. However, even in applications where speed is important, this difference will be compensated for by the economic and quality advantages that come with laser cutting. At the same time, we all believe that further process optimization and cutting with higher output lasers can easily increase the processing speed by a factor of 2 to 3.
