In general, the main factors that cause the woodworking engraving machine to break the knife are as follows:
1. Machining program of wood engraving machine The machining program is the instruction of engraving and machining. It contains position command and speed command. It is the basis of machine tool movement. Therefore, whether the correct and the program are reasonable or not directly affects whether the tool will break the knife.
2. Machine tool itself The engraving machine is the executor of engraving and the provider of engraving power. Whether the engraving machine is selected correctly during processing or whether the current state of the engraving machine is normal will become the influencing factor of the broken knife.
3. Tool The clamping state of the engraving machine tool is also an influencing factor of the broken knife. For example, if the tool is not properly clamped, the radial runout is large, or the length of the tool is too long, it may cause the broken knife.
4. Material The engraving material is the object to be processed. If the material itself is not uniform in hardness and there are impurities, it will cause the knife to break.
5, workpiece clamping If the workpiece is not clamped or the clamping is not strong, it will cause the knife to break.
6. The cutting fluid is obvious when processing hard metals.
7. Peripheral environment For example, if there is vibration source around it, it will affect the machining state and cause the knife to break. If the voltage is unstable or exceeds the working range of the engraving machine, the abnormal working state of the machine will also cause the broken knife.
The above is the main cause of the broken knife in the woodworking engraving machine. Knowing these, we can come up with the right medicine for these situations.
