CNC Engraving And Milling Machine

CNC engraving and milling machine have their own characteristics. A common problem during the engraving process is the phenomenon of broken knives. The main reason is that stone is relatively hard after all. If the cooling water supply is not timely or the processing speed is too fast, the spindle speed is too slow during the engraving process, which will affect the tool and material.

How to solve the problem of broken knives in CNC engraving and milling machine? If the tool breaks, the operator should immediately stop 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 there is, take it out. The most important thing is to analyze the main reason for the broken knife (Stone Mall) to avoid it next time. Then replace the tool. After changing the tool, you should pay attention to defining the origin. After the stone engraving machine returns to the origin of the workpiece, the position of the X/Y axis is correct, but the Z axis needs to be re-determined. This is mainly based on the style of the graphics that have been made to define the operation.

The main reasons for the broken knife of the CNC engraving and milling machine are: the processing feed is too fast or the speed is not enough, the tool quality is poor, the processing cutting amount is too large, the tool clamping length is insufficient or the tool shakes. Of course, it also depends on the processed stone. Different stones have different hardness.
