I wouldn't even use them on a Z axis unless mainly cutting 2D parts with very little Z movement. The Z axis on a CNC machine is the most important part has any weakness here will show in the work quality. Ballscrews from china are so cheap there's no reason to use leadscrew unless you can get it for free.!!
