I have a quickturn 10 mazak lathe with a mitsubishi controller and the spindle is erratic and will jerk but the bearings have been replaced. Anyone here know much about them? Mitsu said it would be $2500 to look at it.....help!!!

Is it a DC spindle motor? if so, check the tach.

hmmm not sure if it is a DC it has 440 3 phase piped in so I doubt it
If its a mazak/Mitsubishi it is either going to be a controlled DC spindle or an AC spindle, not likely to be standard induction motor.
disconnect the drive belt if it has one. If AC spindle, there is a inductive ac tach on the rear of the motor consisting of a toothed wheel and a pick-up with a small box above it with a small circuit board with about 4 pots in it, this can cause erratic behaviour if defective or mis-adjusted, it requires a double beam 'scope to align it, I should have the information sheet if needed.
If DC motor, it is just a straight forward DC tach and may need cleaning.

AL any schematics you can send me please do...I will look into it further
Can you identify wether AC or DC? There should be a motor label or if the motor itself has brushes then its DC.
