Many people wonder if it is possible to use engraving on natural stones. Some years ago it was impossible, but today, in the century of technologies, much is possible. For example, after Endurance’s production of the laser power of 8.5 Watt +, peoples’ dreams become true.
But what is laser engraving? Laser engraving of stone is a type of stone processing with the help of a focused laser beam, through which an image is formed on the stone (drawing, text, pattern, portrait).
Endurance made a few tests and found out that it is possible to engrave on a natural stone surface with a single pass at an average speed of 100-250.
The use of laser equipment in laser engraving of stone has its own subtleties, as the quality of engraving depends on the rock (density, uniformity, etc.).
the most suitable types of stone for engraving are: granite, marble, slate, basalt, marble, salt crystals, pebble, stone slab, natural stone, ceramics, porcelain.
Laser engraving stone is particularly suitable for dark, polished natural stone, such as granite, marble and basalt. The more uniform and fine-grained the stone, the better the results of its engraving. Another ideal material is white marble: here a laser engraver can put on a solid white stone engraving. It is impossible to cut a stone with a laser.
As for the technical characteristics of this laser, the tape of it is Nichia diode. The lens type are 3 element long focal lens / G2 short focal lens. And the operation time, how it was tested, is 48-72 hours continuous.
In terms of performance, the engraving is done very quickly, approximately 1 m2 takes 40-50 minutes approximately (marble). Preparation of a raster file on the engraving takes about 1 to 3 hours, depending on the source and its quality.
For laser engraving stone used laser machines. Most often, laser engraving of stone is carried out using gas CO2 lasers (using carbon dioxide lasers). When the focused laser beam comes into contact with the surface of the stone, depending on the selected radiation power, a microscope or fusion of the stone is formed on the surface.
To achieve a more intense contrast during laser engraving, you can fill the engraving with synthetic resin or lacquer. Especially in the case of polished stones, lacquer or resin is particularly well attached to the engraved (and, accordingly, rough) surface.
Because the surface of the stones is uneven, they are best suited for high-resolution bitmaps (250-333 dpi). Reproduction of very small and detailed images can be difficult under certain circumstances, but this is highly dependent on the stone.
Also this laser has some improvements:
1) Schematics became more efficient and reliable.
2) More efficient cooling system (fans replaced on 7200 RPM) and better heatsink is used.
3) More smart mounts.
4) Increased voltage and a current to the laser diode: 7.2V & 5 – 5.5A.
It has more than 15 accessories, such as goggles, G2 lens, laser connectors, laser mounts and laser actuator.
Surely, if there will be some problems, the company of the laser offers special keys how to fix the problem by themselves. This suggests that nothing terrible and hazardous can happen.
All in all, using this laser makes possible to engrave and cut on your 3D printer and CNC machine. Withal customers will get full customer support and after-sales service.
Laser stone engraving is one of the most popular methods of stone engraving in the world. Currently, laser engraving of stone is widely used in the sphere of ritual services, mainly in the manufacture of tombstones. Laser engraving of stone is carried out on such types of stone as gabbro, basalt, marble, dolerite and other types of stones. And Endurance 8 Watt+ laser can help you in this endeavor.
