Calculating HP for a cutPractical Machinist
Now the Haas Mini mill can come with a 7.5 HP motor But it has 33ft lb of torque at 1 200 RPM I don t know if the Mini mill motor is the same or equivalent to the VF 0 motor If they ARE similarthat 7.5 HP is developed at 1200 RPM and would probably fall precipitously as the RPM increases.
