hey, I bought this spindle from a friend. i got hooked up with an inverter ,but I can't find a manual for it , I want to know how is cooled, can use someone's experience with spindles.
It was on aBusellato CNC machine .

This type of spindle uses compress air for cooling. It takes a good sized compressor to get the volume of air required. You can see the air hose connections. Also ESS compressed air to change the tools
it's weird that it uses compress air as cooling ,that means the air has to be discharged ,thus flowing out and losing compressor power just to cool it.Quote:

I couldn't find it online
It does not use compressed air for cooling, it is an air cooled spindle, which you can see by the fins on the motor housing, it may have a built in electric fan which would need to run to cool the spindleQuote:
