In the processing of stone engraving machines, there are sometimes scenes of broken knives. What is going on here? Someone will ask us if our tool is the best, why is there a broken knife? The following stone engraving machine Xiaobian will analyze this problem for you. It may be the following points:
1. The problem of the process, whether the machining allowance is unreasonable or not, can there be a stepped margin, so that there will be a change in the cutting force during the machining to generate vibration, which leads to the broken knife and the need to add semi-finishing. The other is whether the amount of knife can be too large.
2. Whether the surface of the stone engraving machine has been cleaned, whether the processing sequence is correct or not. These directly affect the starting speed of the engraving machine. The higher the starting speed, the more likely the vibration will occur and the broken knife will easily occur.
3. Whether the surrounding environment of the stone engraving machine is stable and whether the supplied voltage can be stabilized.
4, stone engraving machine auxiliary equipment can be smooth, whether to prevent secondary cutting, more important is the problem of the upper knife. Whether there is dust on the cutter and the chuck, and the strength of the upper knife can be too large. The chuck and nut are not complete. Whether the tool extension can be too long.
5, the status of 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. Can the material in the stone engraving machine have impurities and the hardness is too large?
7. Is the stone engraving machine suitable for processing this kind of data? The speed of the spindle motor can be too low, the spindle motor speed is too low, and the amount of knife per tooth per turn becomes larger, so the cutting force becomes larger, which will cause breakage. Knife.
Through the understanding of the above-mentioned stone engraving machine, I hope to help you.
