The CNC spindle motor (water-cooled spindle, water cooling spindle, CNC router spindle) The router plays a key role in the engraving machine equipment. It can efficiently complete processes such as engraving, drilling, milling and drilling, and has a wide range of applications. It is normal if we meet some problems during use. Do you know what we should do when the spindle does not work?

1. When the CNC spindle suddenly stops rotating, the first thing to consider is whether the spindle itself has a fault. At this time, you can first check whether the spindle has abnormal noise, whether the power is smooth, etc. If there is a problem, you need to repair or replace the spindle.

2. Check whether the spindle is blocked. The spindle may be blocked by dust or debris, causing the spindle not to rotate. Also, confirm that if the spindle needs to be disassembled and cleaned.

3. Power supply problem

If the spindle failure cannot be solved, then the power supply problem is likely to be the cause of the CNC spindle stopping. At this time, you can check whether the power supply is normal and whether there are problems such as a short circuit or an open circuit. At the same time, check whether the switch corresponding to the power supply is normal. If you need to replace the power supply or switch, you need to ask a professional maintenance personnel to handle it.

4. Check whether the spindle motor is damaged. The spindle motor may be damaged, causing the spindle to not rotate. You can check the resistance value of the motor or use a multimeter to measure the speed of the motor to determine whether it is damaged. If the motor is damaged, you need to replace the motor.

5. Check whether the spindle bearing is damaged. The spindle bearing may be worn, causing the spindle to not rotate. You can check the degree of wear of the bearing or use a hand-cranked spindle to check whether the bearing is stable, to determine whether the bearing needs to be replaced.

6. Controller failure

If the power supply is normal and the spindle still cannot rotate, then it may be caused by a controller failure. At this time, we need to check whether the stepper driver and control card are working properly, whether they are connected normally, and whether there are data transmission errors. If there are any problems, the controller needs to be repaired or replaced.

In summary, when the CNC spindle suddenly stops rotating, it may be due to spindle failure, power supply problem or controller failure. In order to avoid this situation, it is recommended that users regularly check whether the various components of the engraving machine are working properly during daily maintenance work, and promptly discover and solve problems to ensure the normal operation of the engraving machine
