What's difference between Air cooling spindle and Water cooling spindle? 

1. As the name suggests, the water-cooled spindle motor uses water circulation to cool the heat generated by the high-speed rotation of the spindle. This method will work well because the temperature after circulation will not exceed 40 degrees. The air-cooled spindle motor uses a fan to dissipate heat, and its effect is definitely not as good as water cooling.

2. Noise. Water-cooled spindle motors are basically silent, but air-cooled spindle motors are loud.

3. In terms of service life. Because the water-cooled spindle motor needs to pay attention to maintenance, change the water frequently or use an industrial water cooler, its service life is much longer than that of the air-cooled spindle motor.

4. Accuracy. The axial and radial runout of the water-cooled spindle motor is basically below 0.003 mm, which is far behind the air-cooled spindle motor (made in China)!

5. Ease of use. Since the water-cooled spindle needs to be connected to a water pump, a bucket is needed to hold water, and a water pipe needs to be connected. Especially in the cold winter in the north, it is easier to freeze, and some customers may find it more troublesome; but the air-cooled spindle will not be so many usage issues.
