RF45 Clone CNC Z axis question

[bogus105]

i've purchased 2 servos for x an y axis. Servos made by ElectroCraft, model E240.

* 0.22 Nm (32oz-in)Stall Torque
* 1.7 Nm (240oz-in)Peak Torque
* 3.1 Amps Stall Current
* 24.5 Peak Current
* 4700 RPM Max Speed
* 48 VDC Max Voltage
* 1.1 kg Weight
* 4.5 kg Radial Load
* 2.3 kg Axial Load
* 7.8 v/kRPM Voltage Const

is it good idea to drive x and y axis with such servos? i consider 1:3 or 1:4 pulley ratio.

also i found bigger servo i consider to drive z axis. Manofacturedby Aerotech, 1000dc series, model 1210-01-1601-03. It has 3000rpm, 210oz-in stall torque, 1000oz-in peak torque, Nema42 sized. Pretty heavy - 5kg. Is it strong enough for z axis?
What timing pulley ratio will be the best?

all axises have a Boschrexroth ballscrews - 25mm dia and 10mm pitch!!! note the pitch. I know that 5mm (approx. 5tpi) would be the best but i can't find such screws for resonable price. I can get 570mm long, 25mm dia and 10mm pitch ballscrew for about US$55. is it good price?

please tell me if these motors will be fine for my zay7045 with 10mm pitch ballscrews
