During the use of the engraving machine, it is inevitable that the knife will break, mainly because the engraving tool is not enough to withstand the current cutting force. It may also be caused by improper operation of the operator

The following summarizes the various reasons that lead to the broken knife of the engraving machine, I hope it will be helpful to the users of the engraving machine

1. It is the material problem of engraving processing. If the material to be processed has uneven hardness and more impurities, it will cause the knife to break.

2. It is the problem of the voltage connected to the engraving machine. If the power supply voltage is unstable, it will also cause the breakage of the tool.

3. The hardness, strength, sharpness of the selected tool and the length of the tool bar are related, and the appropriate tool should be selected according to the different materials to be processed.

4. If the engraving material is not fixed well, the tool clamping is not firm, and the tool holder and the spindle are not concentric, the tool will shake due to the high-speed rotation of the spindle, causing the tool to break.

5. The engraving of the engraving machine is the execution of the engraving instructions, including the position instruction and the speed instruction. The correctness of the processing program will also have an impact on the knife.

6. Do not set the start-up speed of the engraving machine too high. The higher the start-up speed, the easier it is to cause the machine tool to vibrate and the tool to break.

7. The speed of the spindle of the engraving machine is affected by the speed of the engraving machine. When the same product is engraved, if the spindle speed is too low, the cutting force of the tool will increase, and the spindle torque will remain unchanged, which will cause the tool to break, so the spindle speed used should be higher. .

8. If the depth setting of the single cutting tool is too small, the processing time will be longer; if the cutting amount is too large, the tool will break if it cannot bear it.

9. Are the processing range of the machine tool and the tools used in line with the materials to be processed? Whether the engraving machine and the ground are stable may also cause the knife to break.

10. When engraving hard materials such as marble, granite, glass and metal materials, whether to use special lubricant for lubrication.

11. When engraving soft metal materials such as copper and aluminum or other materials with a lower melting point such as plastic materials, the poor chip removal of the tool is also one of the reasons for the broken tool.

The above reasons generally cover the reasons for the broken knife of the engraving machine. If the above situation is ruled out, the broken knife still occurs. It is recommended to contact the engraving machine manufacturer or dealer for on-the-spot investigation.
