The stone engraving machine has special characteristics. One problem that often occurs in the engraving process is the broken knife phenomenon. The main reason is that the stone is relatively hard after all. If the cooling water supply is not timely or the processing speed is too fast during the engraving process, the spindle speed is too slow. It will affect the tools and materials.
How to solve the problem of broken knife in stone engraving machine? If the tool is broken, the operator should immediately suspend the machine, then check the current processing line number and record it in detail. Carefully check the broken knife to see if there is a broken knife body, if it is removed. The most important thing is to analyze the main reason for the broken knife and avoid making it again. Then it is to change the tool. After changing the tool, you should pay attention to defining the origin. After the stone engraving machine returns to the workpiece origin, the position of the X/Y axis is correct, but the Z axis needs to be re-determined. This is mainly based on what has been done. The style of the graphic is used to define the operation.
The reason why the stone engraving machine is broken is mainly: the machining feed is too fast or the rotation speed is not enough, the tool quality is not good, the processing knife is too large, the tool clamping length is insufficient or the tool is shaking. Of course, it is also related to the processed stone. The hardness of different stones is different.
(1) The engraving machine uses high-performance main drive and spindle components. It has the advantages of large transmission power, high rigidity, good vibration resistance and small thermal deformation.
(2) The engraving machine feed drive adopts high-efficiency transmission parts. The utility model has the characteristics of short transmission chain, simple structure and high transmission precision, and generally adopts a ball screw pair and a linear rolling guide pair.
(3) The engraving machine has a complete automatic tool exchange and management system.
(4) The stone engraving machine generally has automatic workpiece exchange, workpiece clamping and relaxation mechanism on the machining center.
(5) The stone engraving machine itself has a high dynamic and static stiffness.
