The difference between water-cooled spindle and air-cooled spindle
1. Water cooling spindle is using of water circulation to cool the heat generated by the spindle rotating at high speed. The cooling effect will be good because the temperature (usually tested) will not exceed 40 degrees after the water has been circulated; the air cooling spindle is cooled by a fan, and the cooling effect is definitely not as good as that of water cooling. Due to this point, water cooled cnc router spindle is more suitable to do the long time carving work than air-cooled spindle. But this is not mean that air cooled spindle cannot do carving jobs, it can do also, just its service life will get reduced after working for more than 4 hours continuously. For example, the carving jobs will take 6 hours to finish; machine with air cooled spindle have to work 4 hours first, then take a rest like 30 minutes, next start again to finish the carving. This way will have no harm on spindle. It will do harm to air cooled spindle to make it work for more than 4 hours continuously. While if same case to water cooled cnc router spindle, you can let it work for 6 hours without rest until finish the jobs.

2. Noisy. The water-cooled spindle is essentially noiseless, but the air-cooled spindle is relatively noisy. 
3. Service life. If we did good maintenance on water cooled cnc router spindle like change water frequently or use industrial chiller for it, the service life of it will be much longer than air cooled spindle.
