To carve a tombstone from the very beginning with a hammer. It takes a day or two to carve a tombstone. It takes one or two days to carve a tombstone. Old practitioners in the tombstone industry believe that they have all experienced it. I am afraid that only those who have experienced it can understand the bitterness . With the development of science and technology, power tools have become popular, and the advent of hand grinders is a boon for the entire industry. No matter how hard a stone is, it can only be rubbed like tofu under a hand grinder. The hand grinder plus various types of grinding heads saves all the practitioners in the stone carving industry, saving heavy physical labor. A skilled operator can even carve a tombstone in more than an hour, which greatly improves the efficiency of carving. But the hand grinder also has a big disadvantage. It is too dusty when carving. If people work under dust for a long time, even if they wear a good mask, they may get pneumoconiosis. Once they get pneumoconiosis, it will be greatly shortened. Human life, so hand grinders are also tools that people love and hate.
With the development of science and technology, machines have gradually replaced handwork, which is also an inevitable trend of social development. Today, people not only have hand grinders to carve stone tombstones, but they can also choose to use various machines to carve stones. They are tombstone sandblasting engraving machine and CNC tombstone engraving machine. The following objectively analyzes the advantages and disadvantages of these two types of machines for everyone. You can choose the machine that suits you according to your actual situation, and the one that suits you is the best.
The basic working principle of the tombstone sandblasting engraving machine is: stick a specific protective film on a clean stone slab, discard the protective film of the parts to be engraved (such as: text, pattern and character image), and then place the stone slab on the carving Under the box, use the powerful airflow generated by the 5.5-7.5 kW air compressor to drive the compound emery in the engraving machine through the nozzle of the engraving gun to sandblast the words, patterns and character images on the slate, and engrave the dust inside the box. The pipe flows back into the engraving machine, after the engraving machine is screened and processed, the emery is recycled and reused, and the dust is discharged into the sewer through the pipe. A sandblasting machine also needs a computer for typesetting, a cutting plotter to output the typesetting content to the engraving film, and a high-power air compressor to cooperate with the work. It takes about 10,000 yuan to get a full set of tools. Sandblasting engraving machine has its advantages: simple operation, one hour to get started, no dust in the engraving process, neat and beautiful fonts, relatively fast engraving of small characters, and typeset fonts for any font you want. The investment amount is not very large relative to the CNC machine. There is no limit to the size of the stone. Disadvantages of sandblasting machine: 1 step is relatively complicated. You need to engrave the word film first, then paste the film on the surface of the stone tablet, then use a utility knife to slowly pick out the font or pattern, and finally use the spray gun to engrave. 2 The entire engraving process also requires manual operation. 3 Only flat fonts and patterns can be engraved, but not embossed.
The effect of the sample engraved by the sandblasting engraving machine
The CNC engraving machine is composed of three parts: computer, engraving machine controller and engraving machine host. Its working principle is to design and typesetting text or patterns through the special engraving software configured in the computer, and the computer will automatically transmit the information of the design and typesetting to the controller of the engraving machine, and then the controller will convert the information into driving steps. Enter the signal with power from the motor or servo motor to control the host of the engraving machine to generate the XY, Z three-axis engraving tool path base path. At the same time, the high-speed rotating spindle on the engraving machine can cut the stone fixed on the worktable of the host machine through suitable tools configured according to the processing material and size, and then various flat or three-dimensional reliefs designed in the computer can be engraved. Graphics or text, realize full automation of engraving operations. Simply put, it is to use the engraving programming software to convert the content that needs to be engraved into a graphic format that can be recognized by the engraving machine control software to achieve the effect of automatic engraving.
The operation process of the CNC engraving machine is to first complete the design of the pattern to be engraved in the design software, select the appropriate tool, automatically calculate the path, output the path file, and then import the output path file into the engraving machine control software, and then run the simulation to confirm that it is correct Then you can start processing.
The advantage of CNC tombstone engraving machine is that it can adapt to various materials such as stone, glass, PVC board, wood board, ceramic tile and so on. The processing accuracy is relatively high, and the quality is relatively stable. After designing the files that need to be engraved, all the rest will be automatically completed by the CNC engraving machine, and there is no need for people to participate in the engraving process. Can carve exquisite relief patterns. The disadvantages are:
1. There are restrictions on the size of the stone, and the size of the processed stone cannot exceed the maximum size of the machine.
2. The price is relatively more expensive than sandblasting engraving machines. The price of CNC engraving machines of different sizes ranges from more than 20,000 to 50,000 to 60,000.
3. The operation is more complicated than the sandblasting engraving machine, and professional training and guidance are required to operate the machine.
