The so-called jump knife refers to the phenomenon that the center of rotation of the tool center and the spindle of the engraving machine are inconsistent during the machining process, resulting in the radial runout of the tool, that is, the meaning of the tool rotation is different. According to the normal machining path of the engraving machine, the high-speed rotation of the tool should be a straight line. If it is not the same, it will become a cone, which not only reduces the precision and effect of the stone engraving machine, but also may cause the tool to break. Happening. So how can we minimize the situation of the engraving machine jumping knife?
1. Pay attention to the matching of the components of the stone engraving machine: the cooperation of the cutter and the chuck, the configuration of the chuck and the nut, the quality of the engraving machine cutter, and the upper knife method. In addition, in the daily work, you should pay attention to the cleaning of the chuck and nut, and clean the dust of the door in time. The strength of the upper knife should not be too large or too small.
2. The length of the engraving machine tool should be small, the rotation speed of the spindle motor should be suitable. For the material of the stone engraving machine, the spindle motor speed is not very high. The material can be selected to the appropriate speed, which can reasonably reduce the tool jumping problem.
3, the cutting strength of the cutter is the main factor causing the stone engraving machine to jump. The tool should be sharp and the front face should be smooth. If it is roughing, use a straight knife to ensure the service life of the tool.
Based on the above three points, the situation of the CNC stone carving machine jumping knife can be greatly improved, the operation is simple, and the effect is also verified by actual conditions.
