The Difference Between Water-cooled Spindle and Air-cooled Spindle Motor of Engraving Machine

Comparison of water cooled spindle and air cooled spindle:

1. The water cooled spindle, as the name suggests, uses water circulation to cool the heat generated after the spindle rotates at a high speed. This heat dissipation method will have a good effect, because the temperature after circulation will not exceed 40 degrees. 

The air cooled spindle uses a fan to dissipate heat, and its effect is definitely not as good as water cooled.

2. Noise

The water cooled spindle is basically no noise, but the air cooled spindle is very loud.

3. In terms of service life

Because it's necessary to pay attention to the maintenance of water cooled spindle, such as frequent water changes or to use industrial water coolers, their service life is much longer than that of air cooled spindle.

4. In terms of accuracy

The axial and radial runout of the water cooled spindle is basically below 0.003 mm, which is far less than the air-cooled spindle!

5. Convenient to use

Since the water cooled spindle needs to be connected to a water pump, a bucket is needed to hold the water, and the 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; while the air cooled spindle does not have so many usage problem.
