How many kW do you want on an aluminum frame? Our mill has a 1.5kW motor and it's 400kg of steel.<br>

The 1kW spindle feels a bit anemic for any metals, is the spindle water<br>
cooled? Air cooled will just get aluminum swarf sucked in and kill it.<br>

Otherwise +1, $100 to the pot if it's watercooled.<br>
