Common faults of the spindle system of the machining center

The main shaft is a power auxiliary device of the CNC machining center, and the main shaft drives the workpiece to rotate to process the workpiece of the rotating body. The spindle is an important guarantee for the high-speed and high-precision machining of the CNC machining center, so the maintenance methods and skills of the CNC machine tool spindle failure are also the knowledge that the operators and maintenance personnel of the CNC machining center must master.

We know that CNC machining centers can be divided into vertical machining centers and horizontal machining centers because of the different movement modes and states of the spindle. Different types of CNC machining centers use different types of spindles, but in general, the spindle system of CNC machine tools can be divided into main transmission spindles with variable speed gears, main transmission spindles through belt transmission, and transmission transmission systems. The dual motors respectively drive the main shaft and the main shaft integrated with the motor and the main shaft.

Common electric spindle of machining center

Spindles with integrated motors and spindles are currently the most commonly used. This type of spindle is usually also called an electric spindle, and the motor itself is the spindle. This main transmission mode greatly simplifies the structure of the main shaft box and the main shaft, and improves the rigidity of the main shaft components. However, the output torque of the main shaft is small, and the heating of the motor has a greater impact on the main shaft. Many spindles of CNC grinders use this method, and the speed can reach tens of thousands of revolutions per minute. Generally, this type of spindle motor is cooled by a circulating water cooling system.

Common faults of electric spindle

1. Overload.

Causes of failure: excessive cutting, frequent forward and reverse rotation, spindle motor failure, spindle drive device failure.

2. The spindle does not rotate

Causes of failure: spindle drive device failure, CNC device can not output speed signal, spindle motor failure, spindle drive device failure, transmission belt break.

3. The spindle speed deviates from the command value

The cause of the fault: the motor is overloaded, the spindle speed command output from the numerical control system is faulty, the speed measuring device is faulty, or the speed feedback signal is disconnected.

4. Abnormal noise and vibration of the spindle

Cause of failure: Generally, it occurs during the deceleration process, and there is a problem with the spindle drive device, such as a failure of the regeneration circuit in the AC drive.
