Calculating Hp For A Cut Practical Machinist

Mar 21, 2009 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 dont know if the Mini-mill motor is the same or equivalent to the VF-0 motor. If they ARE similar - that 7.5 HP is developed at 1200 RPM and would probably fall precipitously as the RPM increases.
