Need Help!- Where to buy servo motors for my bp mill?

[CATCH22]

Im looking to retro fit my bridgeport to cnc I already have the ballscrews but Im not sure what size servo's would be best and also what brand and where to buy them?
Any advice would be appreciated alot!

Thanks Mike

I would love an answer also.

I know stepper stuff, but servo has a STEEP learning curve.

Any primers out there for the servo beginner?

If you use a 4-1 timing belt reduction, you can use the Keling 1100 oz/in servo motors. Are the ball screws a 5 TPI screw ? Use a 1000-2000 line encoder.
He also sells some big enough powersupplys to run them.
My viper 100 drives a BOB and Mach 3 will run it fine.

Yes 5 TPI,but wouldnt a 4 to 1 ratio really slow down the rapids?

I just bought from Keling Inc, good people, fast shipping, very happy. 4:1 will get you 150 ipm no problem, how fast did you want to go? Keling sells AC stuff, expensive though.

I say 4-1 because on a bridgeport there is a lot of mass and size 34 1100 oz/in motors would be a mismatch if coupled 1-1. Normally a bridgeport has much bigger motors.
When your machiining with heavy cuts there is a lot of torque required.
