When choosing cnc router, spindle is a big point that customers will ask.
There are two types of spindle for making a cnc router or wood router: air cooling and water cooling. All people knows that air cooling is expensive, while what is the real difference between the two types of spindle?
About air cooling first:
1. air cooling looks professional, nice in appearance. The most famous brand is HSD in Italy. There are many other manufacturers in other countries, too. Like here, Redsail, China(advertising for ourselves)
2, Its installtion procedure is very simple and easy. It can work well just with air, no need to recycle like water cooling.
3, of course no pollution.
About water cooling:
1, cool the spindle by cycling the water. Its temperature will not be higher than 40 degree, so its cooling result will be better than air cooling(air cooling works by a fan). It can longer the life of the cnc routers.
2, No noise
3, Its working life is longer than air cooling
4, finally, its cheaper, obviously.
But, there is a not very good point: water needs to recycle, so we needs to use a pipe, and it has possibility for water leaking.
Compare the two spindles, we can find that, if you have lots of money, and wants a nice appearance machine, aircooling will be good choice.
But to be practical, water cooling is also good choice.
It depends on what kind of needs you have, and what budget you have.
