Thor, or should that be Zeus?

Well you better get ready for dissappointment if you think 4Kw spindle is going to let you cut at 10mtr/min with any DOC.! There's Reason why Industrial Strength VMC's have 15-20Hp spindles.

This is more for the ability to cut at lower spindle speeds the metals and have there enough power, and i agree with that, but i wonder then if the small mill head rated 10 000rpm, BT30 spindle coupled with servo motor would not do the job better here? I can not remember if there was 10 000rpm variant, cause typically it was 6000rpm. Or just have to be ordered with other bearings.

That could change the design so should be clear before hand. But will give ability to tool change, and hard tap. Cause at the end of the day, why so fast machine if then you will loose time changing tools.

I read a study that said most time in production was spend changing tools, and we are talking a bout machines with tool changers. So obviously not only a tool changer, but a fast one is better.

But i like to say, if the purpose is not clear, the result could be mediocre
