The CNC router machine may encounter various accidents during the processing, among which knife stabbing is an accident. Knife stabbing of engraving machine refers to the sudden penetration of the tool into the workpiece during the movement, resulting in damage to the tool, scrapping of the workpiece and even damage to the precision of the machine tool. In the processing, it is necessary to avoid the appearance of a knife.
When the CNC router machine is running the knife, immediately press the emergency stop switch button on the machine tool to terminate the current processing. Check whether the workpiece is scrapped, and then run the spindle for about 2 hours according to the spindle running-in procedure. If it is a relatively serious stabbing of a larger tool, it is necessary to check whether the accuracy of the machine tool is damaged. If the accuracy is damaged, it is necessary to let the professionals of the engraving machine manufacturer handle it.
The reasons for the occurrence of knives are generally misoperation, processing program problems and machine failures. Therefore, the first thing to check in the operation is to avoid misoperation, and to analyze the path overcut in the path variant to avoid knives. The path appears. At the same time, it is necessary to ensure the stability of the power environment of the CNC engraving machine and the stability of the control computer. These two are important reasons for the failure of the machine tool.
