The machine is equipped with Heidenhain LS 903 scales. The Y axis scale has dry and broken lips, the X and Z ones are intact but still need to be changed. I bought new lips from Franz Singer (Germany).
Yes I have already read that post. In fact, that's where I read where to order the lips.
I still have to decide whether to leave the original electric motor (DC brushed motor with tacho) or mount a 4kW three-phase electric motor with VFD
Yes, I know, if I replace the electric motor I will no longer have the possibility of threading except with the tapping attachments (like Tapmatic),
What do you think?
several threads on Aciera F5 cnc are mine--a few comments
the z axis gib is very poorly designed--top adjusting screw is hollow and has few engaging threads holding the gib
gib itself is soft ductile iron and fractures---dovetail z axis ways more prone to galling and poor fit than Deckel type box ways
you may need to engineer better gib system
I replaced siemens dc spindle motor with ac 3 phase and frequency drive
Centroid control satisfied with retrofit
if Aciera had box ways--I would have kept the F5
