How to calculate motor drive torque for ball screws
· How to calculate motor drive torque for ball screws. May 18, 2016 By Danielle Collins 16 Comments. When sizing a motor, one of the most important factors is the required torque. In general, motor torquespeed curves outline two primary areas of permissible torque: continuous and intermittent. Intermittent motor torque is allowed only for a short time (specified by the manufacturer) and in most ...
.:. Mill Critical Speed Determination
Mill Critical Speed Determination. The "Critical Speed" for a grinding mill is defined as the rotational speed where centrifugal forces equal gravitational forces at the mill shell's inside surface. This is the rotational speed where balls will not fall away from the mill's shell. Mill Inside Diameter: Enter the mill diameter inside the shell (excluding liners). Most mill sizes are reported by ...

HANDWHEEL OPERATORS AND TORQUE
02/07/2013 · Operating torque is applied by pulling on the Handwheel Rim. That's called, Rim Pull. The amount of applied torque depends on the Rim Pull and the Handwheel size. Applied torque = Rim Pull x Handwheel center to Rim distance. Or Torque = Rim Pull x Half the Handwheel diameter. (Example): 80 lb Rim Pull on a 24 inch Handwheel: Torque = 80 lb x 24/2 in = 960 lbin or 960 lbin x ft/12 in = 80 ...
Cutting Speeds RPM Calculations
The rules and principles of cutting speeds and RPM calculations apply to all of the operations being performed on drilling machines. An example of this would be reaming. Reaming is done at half the speed and twice the feed as drilling. This rule still applies on the drill press as it does on the milling machine or the lathe. Pay very close attention to the information introduced in this unit ...

Calculating HP for a cut
· But it has 33ft lb of torque at 1,200 RPM. I don't know if the Minimill motor is the same or equivalent to the VF0 motor. If they ARE similar that HP is developed at 1200 RPM and would probably fall precipitously as the RPM increases. You'd need to get a torque curve chart from Haas to see what your horsepower would be at other RPM speeds.
