Retrofitting a 1986 Maho MH400E

As for Stig's choices on the retrofit I totally agree with you. All the big companies like Mazak, Mori, Deckel, and many others, they dint just take the best component existed the time they made the machines and just put them together. The designers have spent countless hours to make the right compromises. Today’s machines with vector drives to archive similar torque at low rpm with the geared spindles of the past, have 20, 30 Kw motors. For me the only reason to remove that masterpiece of engineering is to put it to my living room. But this is just my opinion, every person things and wants different things.

Looks like you modelled that in Catia. Nice. So is there an access panel there, and you mount the encoder on the panel, or do you have to some surgery on the casting?
Your 600E is incredibly clean.

I have a busy weekend replacing the lounge balcony door and windows, so I won't have much chance to make progress on the MAHO.

I did find a few minutes to finish wiring up the 5V PSU (6T2) and the "Drive enable" relay (19K2).

There is an access panel from the top, the gear gives motion to the horizontal spindle below.

So far all moving components seems to be well lubricated, but they have never move the quill, and the coolant has found a way from bellow between quill and the casting, and now is not moving.

On the cables is this transparent thermo shrinking?
