A I will explain the difference in the following four aspects.

1. Cooling effect. Water cooling method use water circulation to cool the spindle. The temperature of the spindle is guaranteed to be below 40 degrees after water circulation, whose cooling effect will be much better than Air-cooled method.

2. Noise. The water cooling spindle motor is basically free of noise, and the air cooling spindle motor is relatively noisy compared to water cooling.

3. Service life. Water-cooled spindle can be extended the service life by human factors, such as changing water or using industrial water coolers, so its service life is longer than that of air-cooled spindle.

4. Operation. Since the water cooling spindle needs to be connected to the water pump, it needs a bucket to hold the water. And it needs to be connected to the water pipe. Especially in the cold winter in the north, water pipes are easy to ice, which may be more troublesome for customers in the cold winter. At this time, the air cooling spindle is more suitable.
