Engraving has always been an ancient art -- tooth engraving, jade engraving, wood engraving, stone engraving, bamboo engraving, bone engraving and many more...They have become precious artistic heritage in our country. And there are quite many engraving tools -- carving knife, chisel, awl, rapping hammer,etc.. It seems that engraving is an area that has nothing to do with laser.
But in 20th century as the laser technique develops, it “met” the engraving technique and together they become an amazing combination - laser engraving technique. Laser has become a kind of tool of engraving and the materials that laser engraving technique can work are not limited to the above mentioned but also include glass, steel, plastic and many more.
Laser engraving can be divided into outer laser engraving and inner laser engraving. Comparing with outer laser engraving, inner laser engraving is much more complicated but with better artistic effect. It can create certain patterns or characters inside the plastic materials or hard materials that are able to carve or engrave, creating a very vivid or 3D effect.
Since inner laser engraving is more complicated, its working principle is more difficult. The laser light beam will go through some optical parts like beam expander or field lens and enter into transparent objects like glass, crystal, acrylic, etc. from different angles and then laser light beam will meet at a certain spot accurately. In this situation, the optical energy will turn into heat energy to make that spot blast. These tiny blasted spots will be arranged according to different patterns and light and shade value to become the expected patterns. It is complicated, but the effect worth the complicated procedures.
Most of the inner laser engraving machine would adopt air cooling, but for some bigger machines, water cooling is still recommended. S&A Teyu CW-3000 industrial chiller is often the best option when it comes to cooling inner laser engraving machine. This portable chiller unit can radiate 50W of heat every time water temperature rises by 1°C, which is sufficient to cool down the inner laser engraving machine. In addition, CW-3000 industrial chiller features easy installation, easy operation and light weight, making it the perfect partner for inner laser engraving machine.
