.... Please disregard - I've chosen to buy some car radiator coolant which will be thinned with demineralized water. Cheers, Jesper

Hi All,

I have just bought a 2.2 kW water cooled spindle for my CNC and now am considering which water mixture to use to cool the spindle. I have seen that some use a mixture of demineralized water and the coolant used in car radiators but before buying this would just like to ask others what they have good experience with. Preferably I'd like to use something that is odorless, environmentally friendly, and basically close to just demineralized water, if possible ...

Thanks for any advice here,

Jesper
