I want to retrofit a lathe with servo 1.8kw 3000 rpm.
lathe between center is 1.6m and the leadscrew for z axis is 1.8m diameter 30mm 4TPI
i will replace the leadscrew with ballscrew.
What diameter-pitch ballscrew will be optimal for this situation ?
Also what is better to drive the ballscrew with coupler directly from servo or drive it with pulleys & timing belts ?
What pulleys & timing twill be strong enough and without backlash ?
