2.2kw water cooled spindle is widely used on cnc router machines. Different with air cooled spindle, water cooled spindle is cooling by water flow. So this type spindle needs to connect a water cycle system. Water cooling way takes many advantages for spindle, first water cooled spindle have very small noise compared with air cooled; second water cooled spindle can work continuously for more than 10 hours if we keep water temperature in proper status. Because this two points, 2.2kw water cooled spindle is ideal for complicated relief carving jobs which takes long time to finish. Accordingly, 2.2kw spindle water cooled is ideal for multi heads computerised wood carving machine and small size machine like hobby cnc router 6090.

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 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 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 spindle like change water frequently or use industrial chiller for it, the service life of it will be much longer than air cooled spindle.
