The main points of stone engraving machine selection

      In the past years, the stone monument carving, stone sculpture and stone decoration market have been developing at a growth rate of 30-46%. How to improve the processing efficiency, stone carving machine plays an important role in it, then how to choose stone engraving machine?


Stone engraving machine selection has the following three key points:


       1, engraving machine power
       The motor of stone engraving machine has high power and low power. The power of some engraving machines is only suitable for wood carving and advertising engraving. Because of the relatively high hardness of stone, the power is basically 4.5-5.5KW. This high-power engraving machine It is also divided into two categories: one is the negative and always engraving machine. This kind of engraving machine generally processes relatively fine signs. This type of engraving machine has higher requirements for precision; the other type is large-format cutting, the negative is generally 1 meter. Above, but the accuracy of this engraving machine is relatively poor.


       2, engraving machine motor
       The engraving head motor of the engraving machine is also a very important part of the stone engraving machine, and the motor also directly affects the performance of the engraving machine. In addition, it is also important to note that the speed of the engraving head motor is adjustable. If it is possible, it means that the engraving machine has a wider engraving range and the application surface is larger, because different engraving materials must use different engraving head speeds. .


        3, assembly process
       The high-power stone engraving machine requires the body to be precise and stable. The Ord Star stone engraving machine uses a heavy-duty cast iron bed to ensure the stability and precision of the engraving.

Five common faults of engraving machine

   It is inevitable that the engraving machine will malfunction during the process of use. It is very necessary to understand the analysis and solution of some common faults. Here we mainly introduce the solutions to the common five types of faults.


Fault one, alarm failure:
 Overtravel alarm, indicating that the machine has reached the limit position during operation, please check the following steps:
1. Is the designed graphic size beyond the processing range?
2. Check if the motor shaft and screw connection line are loose. If so, tighten the screws.
3. Is the machine and computer properly grounded?
4. Whether the current coordinate value exceeds the software limit value range.

Fault 2, overtravel alarm and release:
1. When the process is completed, all the motion axes are automatically set in the jog state. As long as the manual direction key is pressed, the connection movement state is restored whenever the machine leaves the limit position (ie, leaves the overtravel switch).
2. Pay attention to the direction of movement when moving the table, and must be away from the limit position;
3. The limit alarm needs to clear XYZ in the coordinate setting.

Fault three, non-alarm failure:
1. The accuracy of repeated machining is not enough. Check according to the second item in the first article.
2. The computer is running, the machine does not move, check if the connection between the computer control card and the electrical box is loose. If it is, tighten it and tighten the fixing screws. Imported pump valve industrial washing machine
3. The machine can't find the signal when it returns to the machine origin. Check it according to Article 2. The proximity switch at the machine origin is out of order.

Fault four, output failure:
1. Do not output, please check if the computer and control box are connected.
2. Open the space in the settings of the engraving manager is full, delete the files that are not used in the manager.
3. Whether the signal line wiring is loose, carefully check whether each line is connected.

Fault five, engraving failure:
1. Is the screw of each part loose?
2. Check if the path you are handling is correct.
3. Whether the file is too large and the computer handles the error.
4. Increase or decrease the spindle speed to accommodate different materials (generally 8000-24000).
5. Loosen the knife chuck, clamp the knife in one direction, and put the knife in the right direction to avoid the engraving object is not smooth.
6. Check if the tool is damaged, replace it with a new one, and re-engraving.
