Any equipment and machinery in the production process will have some fault problems, so our CNC processing is the same, but generally lead to the failure of the main shaft, so we can first find the problem from the spindle, the spindle system according to the transmission system can be divided into variable speed gear main drive spindle, through the belt drive main transmission spindle The main shaft is driven by two motors and the main shaft is integrated by motor and spindle. So, let’s learn about the common faults of CNC machining?
- Overload.
Fault causes: excessive cutting amount, frequent positive and negative rotation, spindle motor failure, spindle drive device failure.
- The spindle does not rotate
Fault causes: spindle drive device failure, CNC device can not output speed signal, spindle motor fault, spindle drive device fault, drive belt fracture.
- Spindle speed deviation from command value
Fault causes: motor overload, problems with spindle speed command output from CNC system, fault of speed measuring device or disconnection of speed feedback signal.
- Abnormal noise and vibration of spindle
Fault cause: it usually occurs in the process of deceleration, and the spindle drive device has problems, such as the regeneration circuit fault in AC drive.
The above points are the common faults of CNC machining spindle, and the above editor also talked about the solution. Today, I will talk about it here. If you want to know more information, please visit our website for detailed consultation.
