1. Traditional hand-carving
This processing method is a very primitive carving method, which takes a long time and has low output, but the quality and craftsmanship of Marble Sculpting are more meticulous and exquisite. In traditional hand-carving, you first need to use a pen to write and draw the patterns and characters to be carved. It is no problem for a skilled mason to complete the carving of about 200 characters a day. In a word, the patterns carved by this carving method The speed is slow, and the writing is not standard enough. It requires very high technical requirements for engraving masters, and it takes a long time to get started. However, there are fewer and fewer master craftsmen with this technology, and they are gradually replaced by machines.
2. Power tool engraving
Carving with a diamond grinding head can improve a lot of efficiency compared with pure handwork. This is also a kind of hand lettering, but using modern tools to improve work efficiency. Lettering on Marble Sculpting cannot be wrong. Once a mistake is made, the entire
stone carving will be destroyed. Therefore, manual lettering requires relatively high skill requirements for lettering masters. This kind of lettering method and engraving technology is also relatively common and suitable now. The resulting lettering has a certain depth and is lively and durable.
3. Use Marble corrosion solution
The engraving cost of the corrosion solution is low, the engraving speed is fast in large quantities, and the output is high. The corrosion mixture mainly composed of hydrochloric acid and the calcium carbonate in the Marble can still chemically react to form soluble salts and sediments, and then rinse them with clean water Clean can corrode the engraving effect. However, this method has a disadvantage, that is, it has relatively large limitations. Carving on Marble and white Marble is basically impossible for other
stone sculpture or other materials. The depth of corrosion is relatively shallow, and one millimeter is considered relatively deep. Corrosion lettering is mostly used in industrial processing. Metal materials such as aluminum, copper, and stainless steel can be processed in batches. The pattern and text can be made very small and the cost is low.
4. Small mobile dust-free sandblasting engraving machine
The cost of sandblasting engraving is low and the speed is fast. The cost of engraving a thousand characters with a size of 2cm may only be about 10 yuan, and it only takes a few seconds to engrave a character. The depth can be freely controlled and adjusted. The engraving standard is simple and relatively manual , CNC engraving machine and other engraving methods, it is very convenient to paint after the sandblasting machine is engraved, because first use film glue to cover all the non-character parts, so that it is good to paint or spray paint, and put the tape all over after painting Just tear it off. In addition, the sandblasting engraving machine can engrave a wide range of materials, suitable for engraving on Marble, granite, bluestone, jade, crystal, plastic, acrylic, glass, ceramics, bamboo wood, metal, tiles, background walls and other materials.
Five, computer numerical control engraving machine
The engraving program is generated by the computer to control the cutter of the engraving machine for engraving. The CNC engraving machine mainly has a three-axis linkage method, which does not require a lot of manual operation. The operation is simple, easy to understand and fast. The requirements for the surface of the carved stone carving are not as high as sandblasting and lettering. The engraving has certain advantages, the engraving is relatively standard, and various decorative patterns can be engraved.
But every method has its advantages and disadvantages. The disadvantage of this carving method is that it has requirements for the size of Marble Sculpting. The size of Marble Sculpting should be smaller than the size of engraving machine, and the thickness of stone carving cannot exceed the stroke of engraving machine. Computer engraving The price of the machine is also very expensive. In addition, if you engrave small characters, it is easy to have collapsed edges, and the rules of engraving will appear rigid. The knives are relatively expensive, and it is more troublesome to paint after engraving. After finishing, polish the surface, and then use a computer numerical control engraving machine with strong computer knowledge.
