Acrylic cutting generally uses low-speed machines, because the laser tube power is not very large, and the precision of thin materials is relatively high, and the general speed is not more than 3 meters/minute.
Thick material cutting (10-20mm) 75mm focusing mirror is generally used for plexiglass above 10mm, 100mm focusing mirror is used for plexiglass above 25mm, and the deepest part can cut plexiglass of 32mm.
10mm plexiglass cutting: the cutting speed is generally 0.08-0. 12 m/min, and the light intensity is 60-70%. When the light intensity is 60%, the time is the most stable, and the leaky spray cup adjusts the gas flow to make the edge smoother.
Thin material cutting (2 2- 10/0mm) 5
50mm focusing lens is used for plexiglass below mm, the cutting speed is generally 0.35-0.8 m/min, and the light intensity is 45-65%.
5- 10mm plexiglass generally adopts 63.5.
Mm focusing lens, cutting speed 0. 15-0.3m/min, light intensity 50-75%. If there is serious * * * vibration (vibration) when carving, the accuracy of the engraving machine will also be greatly reduced.
Extended data:
Plexiglass has the above excellent properties, which makes it widely used. In addition to being used as the canopy, windshield and chord window of an airplane, it is also used as the windshield and window of a jeep.
Skylights of large buildings (which can prevent damage), screens of televisions and radars, protective covers of instruments and equipment, casings of telecommunication instruments, optical lenses on telescopes and cameras.
There are many kinds of articles for daily use made of plexiglass, such as buttons, toys and lamps made of pearlescent plexiglass, which are particularly beautiful because of the decorative effect of colored plexiglass.
medical treatment
There is also a wonderful use of plexiglass in medicine, which is to make artificial cornea. If the transparent cornea of the human eye is covered with an opaque substance, light cannot enter the eye. This is blindness caused by leukoplakia of the whole cornea, which cannot be treated with drugs.
Therefore, medical scientists imagine to replace the cornea covered with white spots with artificial cornea. The so-called artificial cornea is made of a transparent material with a diameter of only a few millimeters, and then a small hole is drilled in the cornea of the human eye to fix the lens column on the cornea, and the light enters the eye through the lens column, so that the human eye can see the light again.
