Observation ?

[BobWarfield]

I have two data points for my RF-45 CNC mill's torque under power:

1. It has snapped 3 or 4 1/2" endmills now. Not in a while, fortunately! Lost 2 due to rapids without thinking while getting used to MDI--DOH! Lost 1 or 2 due to inattention, followed by chip welding which made it unusually dull requiring more force, LOL. Easy to go do other things when the CNC is working.

2. Hauled A** with a 3" facemill to see what the max feed it would take was. At 60 IPM it stalled spindle and locked up the table. Chipped an insert, but that was all. Very exciting! Fortunately, this is a servo mill, so once things stop moving, it faults and everything stops.

Would not want a finger anywhere close to being in the way of any part of that mill that wants to move forward. I pop the E-stop any time I've got to reach under the spindle to make an adjustment.

Cheers,
