1, processing procedures
The processing program is the instruction of engraving processing, which contains the position instruction and speed instruction, and is the basis for the movement of the machine tool, so whether the processing program is correct and reasonable directly affects whether the tool will break the knife.
2. The machine tool itself
Engraving machine is the executor of engraving processing, but also the provider of engraving power, whether the engraving machine is selected correctly in processing, whether the current state of the engraving machine is normal will become a factor affecting the breaking of the knife.
3. Cutting tools
The clamping state of the engraving machine tool is also an influencing factor of the broken knife, such as the tool clamping is not complete, the radial runout is large, or the depth length of the tool is too long, which may cause the broken knife.
4. Materials
Engraving material is the object to be processed, the material itself if the hardness is not uniform, there are impurities will cause the broken knife.
5, workpiece clamping
If the workpiece clamping is not solid or clamping is not firm, it will cause broken tool.
6. Cutting fluid
It is evident in the processing of hard metals.
7. The surrounding environment
For example, the surrounding vibration source will affect the processing state leading to broken knives, and the voltage is unstable or exceeds the working range of the engraving machine leading to the abnormal working state of the machine tool will also cause broken knives.
