Acrylic, also known as PMMA or plexiglass, acrylic, is an important plastic polymer material developed earlier, with good transparency, chemical stability and weather resistance, easy to dye, easy to process, beautiful appearance, acrylic products are acrylic panels, acrylic plastic particles, acrylic light boxes, signboards, acrylic bathtubs, acrylic artificial marble, acrylic resin, acrylic (latex) paint. Acrylic adhesive and other products, a wide variety. At present, the application of acrylic is becoming more and more extensive, in the construction industry, lighting projects, instrumentation parts, automotive lamps, optical lenses, transparent pipes have a wide range of applications.
Acrylic is the best new titanium material after ceramics can manufacture sanitary ware, compared with traditional ceramic materials, acrylic has a high brightness, good toughness, not easy to break, strong repair, soft texture, bright colours and so on; at the same time, acrylic has the disadvantages of production difficulties, high cost, so acrylic products according to market demand for different high and medium grade products, the processing requirements gap is also a lot.
Acrylic polishing is an important process of finished product processing, before the cutting process after the cut surface is relatively rough, the surface will also become fuzzy, in order to restore gloss and transparency, it is necessary to acrylic polishing process, the following are commonly used 3 kinds of polishing process.
Through high temperature (800-3000dc) on the edge of the acrylic product polishing process, through the flame polishing of acrylic, the edge to play a bright effect. The effect of this polishing process is relatively poor, the principle is to use alcohol-fuelled gun flame burns the rough surface, so as to reach the polishing effect. Advantages are low processing costs, fast, time-saving, suitable for not very high requirements, relatively cheap acrylic products.
Polishing effect is much better than flame polishing, the advantage is not only can polish the plane, can also polish the irregular acrylic display, the disadvantage is manual operation, a lot of polishing can not, slow, low efficiency. Suitable for demanding acrylic products and other products, sometimes also used with diamond polishing to achieve the best results.
The use of professional-grade semi-automated polishing equipment, the advantage of high efficiency, especially the polishing of straight acrylic surface, the disadvantage is that you can only polish the plane and oblique, can not polish the surface. Acrylic display racks, plexiglass display racks, etc. are basically using diamond polishing machine with diamond polishing knife to polish.
Acrylic polishing cutter (milling cutter), clamped in the polishing machine on the special disc, for acrylic organic plate high light polishing, precision machining, the set of tools generally consists of two rough cutter a fine milling cutter composition, or a rough cutter a fine cutter. Rough cutter cutting edge material for the CDW302 polycrystalline diamond PCD; fine cutter cutting edge material is generally selected single crystal diamond, that is, diamond polishing knife, after polishing treatment, diamond surface made into a circular arc type, thrown out of the acrylic sheet does not need to go through the cloth wheel, can be directly to achieve the effect of the mirror, crystal clear, the fine cutter of another advantage lies in the convenience of grinding, only need to repair grinding straight edge can be achieved circular arc Another advantage of the knife is easy to sharpen, only need to sharpen the straight edge to achieve the arc of the cutting point of the opposite high-gloss effect, greatly saving the cost of sharpening to increase service life.
