Thor, or should that be Zeus?

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

Agreed. The current idea was a 4KW Chinese (or better) spindle.

Three points. This design is not final, could look at changing it.

Second point, It is possible to do a tool changer directly into a non geared spindle setup (like the Datron tool change setup).

Lastly, If I am doing masses of small things, like a pallet of 10 things, using the same tool for an extended period of time and then changing will have less time impact. Of course, doing a 1 off with 5 changes will struggle.

The Tormach setup is interesting, no real ATC however has the drawbar, if you manage your tools properly (heights preset etc) doing a manual change during cycles is not too bad.

But please keep the feedback coming, this is useful.
