Much of my milling would be for hobby projects in Aluminium, but some semi-professional work is also possible. In any case, based on the information I have now, I can stick with a non servo spindle for now and later maybe add a servo based one if need arises.

I am yet to finalize the ballscrews. I asked TBI motion about authorized sellers. Even Digikey and RS seem to stock their stuff they don't seem to stock parts I am looking for. Lets see if https://www.tuli-shop.com is a genuine seller.

Regarding motorized ATC spindles, I see two major verities in aliexpress. A cylindrical type such as this and a boxed type one like this. Does any one know if these target different use cases?

first one is watercooled so it's quiet second is air cooled so it's loud.
