In the process of using the engraving machine, it is inevitable to break the tool, mainly because the engraving tool is not enough to bear the current cutting force. It may also be caused by improper operation of operators.

The following is a summary of the various reasons for the cutter breakage of the engraving machine, hoping to be helpful to all engraving machine users.
1. It is the material problem of engraving processing. If the hardness of the processed material itself is uneven and there are many impurities, it will cause knife breakage.
2. It is the voltage problem connected to the engraving machine. If the power supply voltage is unstable, it will also cause the cutting tool to break.
3. The hardness, strength and sharpness of the selected cutting tools are related to the length of the tool bar. Appropriate cutting tools should be selected according to the different processing materials.

4. When the engraving material is not fixed well, the tool clamping is not firm, and the tool rod and the spindle are not concentric, the tool will be broken due to the high-speed rotation of the spindle and the shaking of the tool.
5. Engraving machine engraving is the execution of engraving instructions, including position instructions and speed instructions. Whether the processing program is correct or not will also have an impact on the knife.
6. The starting speed of the engraving machine tool should not be set too high. The higher the starting speed is, the more likely it is to cause vibration of the machine tool and tool breakage.
7. The rotation speed of the main shaft of the engraving machine affects the engraving of the same product. When the rotation speed of the main shaft is too low, the cutting force of the tool becomes larger, and the constant torsion of the main shaft will cause tool breakage. Therefore, the rotation speed of the main shaft used is still higher.
8. The depth setting of single cutting, the cutting amount is too small, and the processing time becomes longer; If you eat too much, the knife will break if it can’t bear it.
9. Is the machining range and tool of the machine tool consistent with the processed materials? Whether the engraving machine tool is stable with the ground may also cause knife breakage.
10. Whether special lubricants are used when carving hard materials such as marble, granite, glass and metal materials.
Hollowed out wood carving
11. When carving soft metal materials such as copper and aluminum or other materials with low melting point such as plastic, poor chip removal of the tool is also one of the reasons for tool breakage.
