Bridgeport Conversion Torque Reqm't
I am considering doing a CNC conversion on an older Bridgeport. I am
wondering what the torque reqm't would be for stepper drives. I have some 300 oz steppers, but I don't think they would be big enough. Maybe ok for the X/Y, but definetly not for the Z(if I move the knee). Anyone out there have a good number to stick to these? For now, I plan to use the stock ACME screws, but would like to upgrade to ballscrews at some point. I know that the ACME screws are going to have a higher torque reqm't. JW |
