I have a PM-30MV on order, and I'm considering possibly upgrading the headstock/spindle assembly from R8 to BT30.

The thought is to replace the spindle with a Chinese BT30 belt-driven spindle to get 6000/8000/10000 RPM, and combine it with a 1.5kw/2.2kw AC servo spindle.


The headstock would be replaced with an assembly made of 3/4" steel plates and 3/4" wall steel tube, with 1" steel plate for the back plate to attach to the Z axis dovetail block.

And eventually, to add one of these BT30 ATC assemblies.

Would this kind of spindle and motor be too much for the PM-30MV?

Keep in mind, it already has a 3000 RPM spindle and a 1.5KW brushless motor.

Sanity check requested.
