How Tombstones are Engraved？

Tombstones in our lives will not be unfamiliar, on the contrary, we will feel familiar. The purpose of the tombstone is well understood, but when asked how the tombstone is carved, it is estimated that everyone is a piece of astonishment and bewilderment. When it comes to tombstones, many people avoid them and are not willing to talk more about them if there is no real need, not to mention the process and methods of tombstone carving. Because it is related to funeral and burial, on the one hand, it is regarded as Yin too heavy and not too auspicious, on the one hand, it is easy to arouse people's feelings of missing their loved ones who have passed away. With the development of society and science and technology, tombstone carving techniques are constantly innovating, no longer only a single traditional carving method, but with the development of science and technology to extend a variety of carving processing methods. Today, I will introduce to you several methods of tombstone carving at present: 

One: traditional hand carving  

This processing method is a very primitive way of carving, time-consuming, low yield, but the quality and technology is meticulous and exquisite. Traditional manual sculpture to pen to write out to carving decorative pattern and text drawn, skilled master masons a day to complete two hundred words or so words carving is no problem, in a nutshell this method of sculpture carved decorative pattern is slow, and text is not standard, technical requirements of carving master is very high, for a long time to entry, But now there are fewer old masters of this kind of technology, gradually replaced by machines.  

Second, sculpture with corrosive solution  

The etching cost is low, the mass carving speed is fast, and the output is high. The hydrochloric acid corrosion mixture can react with the calcium carbonate in the marble to generate soluble salt and precipitate, and then wash it clean with water can corrode the carving effect. But this method has a disadvantage, is relatively large limitations, in marble and white marble sculpture, other stone or other materials can not be carved.  

Third, the stone tablet sand blasting engraving machine to sculpture  

Sand sculpture of low cost, fast speed, carving a 2 cm one thousand specifications of the word cost only 10 yuan, carved could only take a few seconds, a word can control freely adjust the depth of engraving standard, the operation is simple, relatively manual, CNC engraving machine carving way, such as after sandblasting machine carved lacquer is very convenient, because use first film glue all the font part covered, Just paint or spray paint, and then peel off the tape. In addition, sandblasting engraving machine can be carved with a wide range of materials, suitable for marble, granite, bluestone, jade, crystal, plastic, acrylic, glass, ceramic, bamboo, metal, tile, background wall, etc. Lettering, pattern, lace, Yin carving, Yang carving, plaque, tombstone, monument of merit, decoration pattern... . Not limited by material size, text or pattern size and area. All kinds of fonts, calligraphy, calligraphy, celebrity calligraphy and painting... All can be carved. Sandblasting carving is the use of high pressure air flow to drive the emery high-speed impact of the surface of the stone monument (or other materials), there is a protective film position can not be carved, no protective film protection position can be carved in the way of carving. To use the engraving machine to carve the words or pictures need to be engraved on the protective film, the protective film engraved and painted content affixed to the clean stone (or other objects) surface, uncover the content to be carved part, you can be carved. Simple operation, the price of several thousand yuan, the use of low cost, generally computer typing (or handwriting) can be operated, no maintenance costs, the tablet (or other objects) surface is flat or curved or irregular without requirements, the size of the tablet is unlimited, can move sculpture. As long as the surface can stick protective film can be carved. After carving good stele, color (such as: gold paint or red paint), when the paint is dry, peel off the protective film, of course, you can not color. Stone tombstone sandblasting engraving machine application is very wide, whether it is marble, stone, tombstone, stele, ceramics, glass, etc., can be carved, so some places different industries are also called stone engraving machine, tombstone sandblasting engraving machine, stone stele sandblasting engraving machine.  

The fourth is CNC engraving machine  

CNC engraving is to be processed stone tablets on the engraving machine fixed. There is a limit to the size of the stone tablet. The stone tablet cannot be larger than the engraving machine. Then through the computer generated engraving program to control the engraving machine tool running engraving. CNC engraving machine by three axis linkage carving, the price of more than thirty thousand only practical, high cost of use, maintenance costs, high requirements for workers to operate, the tablet surface must be flat, no error, surface error will cause carved product depth is different, feed difficult, easy to damage the tool. There is no film protection on the surface of the stone tablet, so it is difficult to paint after carving. Working with harsh high-frequency noise. Stele (or other objects) surface error problem is very headache, especially when engraving small words or line carving, the feeling is more profound, not convex place is too deep, or concave place is too shallow, slightly do not pay attention to the convex place may cause damage to knives and carving materials. General users can not carve on curved and irregular objects.
