If the 430 Oz-In is continuous, that will be more than enough. Even if that
is the peak torque, it will likely be enough. 100 IPM requires 500 RPM
on the screw, so a 3:1 belt ratio would still allow you to reach that speed.
With 3:1 reduction, you get 430 * 3 = 1290 Oz-In at the screw. That
is 80.6 Lb-In. That will produce 2535 Lbs of linear force at the machine
slide! You say you need MORE than a TON?!!!
