There are many types of plexiglass materials. There is a big difference between imported and domestic products. Imported organic glass cuts very smoothly. Some domestic impurities are too much and will foam. Acrylic cutting generally uses low-speed machines, because the power of the laser tube is not very large, and the precision of the thin material is relatively high. Generally the speed does not exceed 3 m / min.

　　For thick material cutting (10-20mm), the plexiglass above 10mm generally uses a 75mm focusing lens, the plexiglass above 25mm uses a 100mm focusing lens, and the deepest can cut 32mm plexiglass. 10mm plexiglass cutting: Generally, the cutting speed is 0.08-0.12 m / min, and the light intensity is 60-70%. When the light intensity is 60%, the light is the most stable, and the air jet cup adjusts the air flow to make the edges smoother. Because the larger the blow, the molten object is blown back to the plexiglass by the auxiliary high pressure gas to form a matte surface. Try to keep the wind down. Sometimes, the customer needs to add paper or film cutting. At this time, the wind cannot be too small, otherwise it will catch fire. The speed and light intensity must match well when cutting Plexiglas. The slower the speed, the better the smoothness. Imported high-power lasers are best for plexiglass above 15mm. When plexiglass is used for engraving, use a blow-by air jet cup. Try not to sculpt too deep. It is difficult to sculpt too deep. The greater the gas, the more sculpted the effect of the sculpting edge. The engraving need to pay attention to the resolution setting. If the output is in BMP format, the resolution should generally be above 600dpi. At this time, the speed is 8-18m / min and the light intensity is 20% -30%. When blowing, turn off the air to make the bottom Smoother.

　　For cutting thin materials (2-10mm), the plexiglass below 5mm uses a 50mm focusing lens. The speed when cutting is generally 0.35-0.8 m / min, the light intensity is 45-65%, and the 5-10mm plexiglass generally uses a 63.5mm focusing lens. When cutting, the speed is 0.15-0.3 m / min, the light intensity is 50-75%. For large-area engraving machines, if severe resonance (vibration) occurs during engraving, the accuracy of the engraving machine will be greatly reduced, so the cutting The size of the plexiglass model should not exceed 1 meter, and some white powder is generated during the sculpting of the plexiglass figures, so that it feels clearer. If it is engraved, it needs to be wiped with water to make it more blurred. It depends on what kind of processing is done for specific effects.

　　Physical properties of plexiglass:

　　Density: 1.19g / cm3, Light transmittance: 99%, Impact strength ≥ 16kg / cm3, Tensile strength ≥ 61Kg / cm3, Thermal deformation temperature ≥ 78 ° C, Thermal softening temperature ≥ 105 ° C

　　The bonding method of plexiglass should be based on different needs. The 502 can be less demanding, but the demanding chloroform is not necessarily the best for short. Chloroform is not necessarily the best. Acetone is also required, but it is best to use several mixed formulas.
