The causes of common mechanical failures in CNC machine tools: Among the common failures in CNC machine tools, mechanical failures often have obvious characteristics.
1. The orientation position of the machine tool spindle is inaccurate, but the machine tool did not sound an alarm. Possible reason: Due to the current machine tools, the spindle orientation generally adopts the encoder orientation method, and the spindle and spindle motor are connected in a 1:1 ratio, directly using the built-in encoder orientation of the motor. Therefore, the occurrence of this situation must be due to a problem with the mechanical connection part& nbsp;
2. The positioning accuracy fluctuates, and the machine tool does not sound an alarm: possible reason: poor connection of the mechanical transmission chain. Such as loose coupling.
3. Overloading of machine tools: Overcurrent alarms and abnormal motor heating often occur. Possible reason: Poor mechanical assembly, resulting in heavy mechanical load. For newly designed machine tools, selecting a servo motor that is too small can also result in this phenomenon. Additionally, incorrect servo parameter settings can also trigger this alarm.
4. Machine tool auxiliary actions, such as tool changer actions, have output signals that control their actions, but the actions do not. Possible reasons: mechanical jamming, pipeline blockage, etc. Note: When the machine tool malfunctions, it is often a combination of mechanical and electrical components. As there is relevant training for the mechanical part, it will not be repeated here.
