What ballscrew/ballnut(is better single or double ?)/pulleys/timing belt have you used for Z axis ?
Do you know some tutorial/webpage how to design a breakout board ?
I have some knowledge in electronics so i believe that i will do it myself..

Perfect!
The next step is to install automatic tool change turret.. check to aliexpress/alibaba have some cheap-simple chinese auto turrets.
I want to ask you what ballscrews have installed and how much reduction you have ?
Are the rapids 5m/min fast for common applicatons or if it was faster will be better?
I ask you this because i have ordered higher power servos so i have enough torque
to run at higher speed... but higher speed that 5m/min is usable ?

No i don't want external encoder i want parallel port but to connect servo drives with
pc i need a breakout board right ?
What breakout board must buy with these specs to connect these servos with mach3 ?

I don't have manual and if i find i would be written to chinese so it would be useless
I have this translated page witch shows pinouts of driver
http://translate.google.com/translate?sl=zh-CN&tl=en&js=n&prev=_t&hl=en&ie=UTF-8&layout=2&eotf=1&u=http%3A%2F%2Fwww.ibuyla.com%2FProduct%2Fdetails%3Fnum_iid%3D14836946575&act=url
Also i think that this drive http://www.cncmakers.com/uploads/soft/manuals/SD200_AC_Servo_Driver_User_Manual.rar is simillar to my drive (same chinese pcb but with other outer case) 

Yes i want to connect in lathe and for turret tool changer i ask if it is possible to support this feature
iam not having any turret now but iam planning to buy one like this
http://www.aliexpress.com/item/NC-turret-LD4-0620/823135700.html in future

You say that i need a controller which supports threading ...
If iam right mach3 supports threading so why i need controller that supports threading ?
Mach3 will be my controller so i need a board to connect pc with servo drives to control them from mach3

What breakout board/motion controller need to control these servo drives from mach3 ?

If possible i want board to support
>=3 axis
>=6 home-limiting switches (optical endstops)
1 optical spindle sync endstop (lathe spindle)
option to control spindle speed with vfd (inverter)
manual operation with joystick & jog speed control
option to switch on/off cooling fluid (to switch oil solenoid electric valve)
emergency stop
points in cutting tool
pause or reset cutting operation
ability to control tool turret

The pc has parallel & usb & ethernet port and i can install 32 or 64 bit windows.

thank you

the breakouts witch is for stepper drivers work with servo drivers ?

Iam planning to use these drives with matched servos without reduction
http://www.ibuyla.com/Product/14836946575/

What breakout board to suggest me supporting
>=4 axis
>=6 optical endstops
1 optical spindle sync endstop
option to control spindle speed with vfd
manual operation with joystick & jog speed control
option to switch on/off cooling fluid (to switch oil solenoid electric valve )
emergency stop
points in cutting tool
pause or reset cutting operation
ability to control tool turret

It doesn't matter the if is parallel or usb
Are these ok ?

Thank you very much for your reply.
Because is not easy for me to make torque tests because if i disassemble the lathe and install ballscrews i will not have machine to make the modifications so from your experience this selection will be ok ?
for z axis: 32mm diameter 5mm pitch ballscrew 750w/3000rpm yaskawa/mitsubishi servo with reduction 1:3
for x axis:16mm diameter 5mm pitch ballscrew 400w/3000rpm yaskawa/mitsubishi servo with reduction 1:3

If i put steppers this will be ok?
for z axis: 32mm diameter 5mm pitch ballscrew nema42 4200oz with reduction 1:2
for x axis:16mm diameter 5mm pitch ballscrew nema34 1600oz with reduction 1:2

On your machine how much is the torque for z and x axis ? I will suppose that in my machine the torque will be 1.5 times higher than yours...

I will go with parallel port this encoder will be ok ?

Can i put with some hack to mach3 an incremental optical rotary encoder for better resolution or not ?

Sorry for the of topic (if there is a problem please delete it)
Hello!
Iam new member and i want to convert my lathe like yours.
I haven't done any cnc conversion before and i need some help.
I have a lathe like that http://images.ua.prom.st/28306498_w640_h640_27032013431.jpg with 2.2kw 3phase spindle motor and 1.4m z axis distance.
I want to buy for x and z axis 2 servo motors+drivers or 2 stepper motors+drivers but i don't know what motors and drivers to choose(power/rmp/torque).
If i put servo motors i will need reduction by pulleys and timing belts but what ratio reduction will be optimal ?
For spindle what encoder will be ok ?
thank you.
