Hello to all,
Want to share my story.
it started with Weiss WMD25V mill converrion, after I wanted more power and working area, so I build large metal monster. this one was not rigid enought to process Steel and machining Speed was to slow.
So I decide to buy Real machine frame:
WOW! Where did you get the frame? It looks new.
Nice, that's a really good find.
I like the Robodrills, very versatile. Interesting how small that Z ball screw looks compared to the size of the head.

Very interested to hear where it was bought, though.
Hello,
Sorry For late reply.
BK-BF blocks it is from me, Hiwin also my idea :D, Frame came with no linears and ballscrews. all other mountings my job.
I am very begginer in this job and I am sure that Parts i chose for this frame is not perfect, but I will share all info:
Linear motions:
for X and Y axis - Hiwin HG series 25mm. (original comes with NSK).
for Z axis - Hiwin RG series 30mm linear, this series of linear I have used first time and I can tell that it is much more rigid and curate.
Ballscrews:
China manucatured dual ball nut ballscerws, very cheap but looks like in future I will change it, No backlash but it is not accurate I need.
CNC system - Mach3 Board.
Axis electronics - Stepper motors and drivers:
X and Y - 110HS28 - 28 N.m (3,965 Oz-In) 2 Phase NEMA 42 Stepper Motor; 1A phase current
For Z - 110HS28 - 28 N.m (3,965 Oz-In) 2 Phase NEMA 42 Stepper Motor; 1A phase current
Drivers - Leadshine DM2282
Spindle motor - 3.5KW 3 phase motor 3000RPM controlled with inverter.
Spindle - China ATC BT30 Spindel,
Yes Frame is new. Unused.
this is how machine looks like now:
