1. The machining center jam tool caused by incorrect spindle orientation angle;
The cause of incorrect orientation angle is generally caused by collision, or the spindle synchronous tooth shape belt has a problem, resulting in an error in the orientation angle, and inaccurate orientation will also cause problems such as abnormal tool change in the tool magazine.
2. The machining center jam tool caused by the abnormal position of the origin of the second tool change;
The cause of abnormal tool change point position is generally the operation error caused by the operation error of the machining center operator, the most likely to lead to incorrect tool change origin, this phenomenon is usually manifested as tool arm pulling out the knife, loading abnormal noise, and even leading to jamming, if this situation for a long time the tool arm will also be damaged.
