Friends who have used high speed cnc machining know that the CNC machining center is equipped with a manipulator tool magazine, which is equipped with multiple tools with different processing functions. The frequency of use of the tool magazine and automatic tool changer during workpiece processing Very high, especially for the processing of complex parts. The processing content is much. The tool change action that the robotic arm needs to perform will frequently change the tool according to the machining center system program. In this case, the tool magazine will also have problems of this kind, among which the phenomenon of tool magazine jam in the machining center is more prominent. This is also a problem encountered by many machining center users. What is the cause of the tool magazine jam in the machining center? As a professional machining center manufacturer, our technicians summarized this problem.
There are many reasons for the malfunction of the tool magazine of the CNC machining center. The simplest reason is that the kinetic energy is cut off and the tool change action stops. In general, the power failure occurs suddenly when the tool is changed. Another common reason is that there is a problem with the air source of the machining center, and the air pressure is insufficient, which causes the tool to be unable to be pulled out normally. I believe everyone can understand that the jams caused by these two reasons can be easily solved. But technical reasons are not so easy to solve.
For example, the tool jam caused by the abnormal position of the second tool change origin of the tool magazine or the tool jam caused by the incorrect spindle orientation angle. Specific solutions are listed in detail for everyone:
1. Machining center jam caused by incorrect spindle orientation angle;
The reason for the incorrect orientation angle is generally caused by machine collision, or a problem with the synchronous tooth belt of the spindle, resulting in an error in the orientation angle. Inaccurate orientation will also cause problems such as abnormal tool change in the tool magazine.
2. The machining center jam caused by the abnormal position of the second tool change origin;
The reason for the abnormal position of the tool change point is generally the machine collision caused by the operation error of the machining center operator, which is most likely to cause the tool change origin to be incorrect. This phenomenon is usually manifested by the tool arm pulling out the tool, installing the tool abnormal noise during tool change, or even It will cause the knife to jam, and if this happens for a long time, the knife arm will also be damaged.
