CNC machining centers are equipped with arm type tool magazine. In the process of workpiece machining, the use frequency of tool magazine and automatic tool change device is very high, especially for the processing of complex parts. The tool change action to be performed by the mechanical arm of machining content will be set according to the machining sequence of the CNC machining center system program, and the tool will be changed frequently. In this case, there will also be problems in the tool magazine, among which the tool stuck phenomenon in the tool magazine of CNC machining center is more prominent. This is also a problem encountered by many machining center users.

Tool jam of CNC machining center caused by 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 lead to the incorrect origin of the tool change. This phenomenon is usually manifested in the abnormal sound of the tool arm during tool pulling and loading, and even the tool jam. If this situation lasts for a long time, the tool arm will also be damaged.

There is a problem with the air supply of the CNC machining center, and the air pressure is insufficient, which makes the tool unable to be pulled out normally.

Tool jam of CNC machining center caused by incorrect spindle orientation angle.

The causes of incorrect orientation angle are generally caused by machine collision, or problems with the synchronous tooth profile belt of the spindle, resulting in errors in orientation angle. Inaccurate orientation will also cause abnormal tool change of the tool magazine.

When the kinetic energy is cut off, the tool change action stops. Generally speaking, there is a sudden power failure during tool change.
