I often receive calls from customers, saying why the tool is broken, and it is very serious. In fact, this is related to the use of stone carving machines, stone carving knives, and the lack of understanding of stone craftsmanship. You can accumulate experience in use, what stone What kind of tool is used, what kind of feed speed is used, and it is also related to the path of the programmer. To put it simply, there are several reasons why the stone carving knife is broken.
1. Due to the machine of the cnc router machine itself, the Z axis speed is too fast, it is easy to break the knife, and the deformation of the tool holder can easily break the knife. Choose the spindle power, generally 3000W for a stone cnc router machine, the processing speed can be guaranteed, and it can save electricity; at the stage when the technology of the stone cnc router machine is not yet mature, choosing a better quality stone engraving knife is something you must consider .
2. The material does not match. Diamond is suitable for engraving marble, but it is impossible to engrave all engravings and calligraphy. Diamond is suitable for hard stone with fine texture. The service life of the tool is closely related to the speed of the knife. The harder the stone, the slower the speed of the knife.
3. There is water in the working environment of stone carving. If there is no water to cool down, the residual heat will be easily broken. The contact part of the knife tip and the stone must have sufficient circulation and sufficient moisture.
4. When programming, it is necessary to ensure that the flexible feed is required every time the knife is cut; the requirements for the operator: During the programming, the flexible feed must be ensured every time the knife is cut. The tip of the knife will be in contact with the object when it is rotating.
The above is the reason why stone carving tools are easy to break. Experience is slowly accumulated. Novices can analyze the reasons without interruption, and then record them. After a long time, they will be very experienced.
