The magnitude of vertical (squeezing) force required to counteract the radial (horizontal) cutting force is a function of the friction between the work piece and fixture. Assuming a coefficient of friction of .15, then the minimum swing clamp force required to resist the 72 pounds of cutter force would be: Clamping Force =. 72lbs/.15. = 480 lbs.

And eliminating the need for the weld (or cold-formed) nut is one way to achieve that simplification. When the screw's threads mate with the helix form in the sheet metal, they create a secure connection. With the High Torque Fastening System, the mated material (that is, the sheet without the helix form) can be up to 2.5 mm thick.

Milling head or CNC router spindle for cutting aluminum?

Milling aluminum (6061) doesn't require nearly as much torque as milling steel but more torque is usually better than less. The higher the spindle speed, the more power you need to maintain decent torque. This is why large high speed CNC mills have crazy huge 40hp spindle motors (or more). Take a look at the Hass mini mills for an example.
