However, as the numerical control technology becomes more and more mature, it is not satisfied with the pursuit of machining accuracy, but also with high machining efficiency.

In the processing technology of glass, ceramics and sapphire, etc., CNC engraving machines are often used to process curved surfaces. A single-spindle engraving machine can only process one product at a time, which has low processing efficiency and cannot make full use of resources. Although a multi-spindle engraving machine can process multiple products at the same time, it will greatly increase the production of the engraving machine. cost.

Because the right end of the grinding wheel tool of this improved technology is placed in the bearing on the fixed bracket, there is a certain gap. During the high-speed rotation of the grinding wheel tool driven by the spindle, the coaxiality of the left and right ends of the grinding wheel tool cannot be guaranteed to be consistent, resulting in During the process, the grinding wheel tool will splash out, which will bring great safety hazards to the production. In addition, due to the defects of the overall design structure of the horizontal grinding machine involved in this improved technology, the three axes cannot move at the same time, which limits the processing of plates such as glass, ceramics, and sapphire with large differences in size, and it takes a long time to adjust the fixture .
