In the process of using stone engraving machine, there is sometimes a phenomenon of broken knife. Today, Shandong engraving machine manufacturers analyze this problem for you, so that users can adjust it in time. Below, follow the Shandong engraving machine manufacturers to see:
1. The problem of the process, whether the machining allowance is unreasonable, whether there is a stepped margin, so that there will be a change in the cutting force caused by the vibration during the machining, resulting in the broken knife and the need to increase the semi-finishing. Is it too big to eat?
2. Whether the phase path of the stone engraving machine control system has been smoothed, and whether the priority mode is correct, these directly affect the starting speed of the stone engraving machine tool. The higher the starting speed, the easier it is to generate vibration, which easily leads to broken knife.
3. Whether there is a source in the surrounding environment of the stone engraving machine, and whether the voltage provided is stable.
4. Whether the auxiliary equipment of the stone engraving machine is smooth, whether it avoids the secondary cutting, and more importantly, the problem of the upper knife. Whether there is dust on the cutter and the chuck, the strength of the upper knife is too large. Is the chuck and the nut not? In good condition. Is the tool extension too large?
5, the stone engraving machine tool, including the hardness, strength, sharpness of the tool, as well as the length of the extension, the smoothness of the rake face and so on.
6. Is there any impurity in the material processed by the stone engraving machine? Is the hardness too large?
7. Is the stone engraving machine suitable for processing, whether it is suitable for processing this kind of material, whether the machine is leveled, if it is not leveled, it may cause the broken knife. The spindle motor speed is too low, the spindle motor speed is too low, every tooth per tooth The amount of the knife will become larger, so that the cutting force will become larger, which will cause the knife to break.
