Granite framed dental milling machines

[Sliding Head]

I would like to offer a pair of granite frames CNC dental milling machines for sale. They have not been used for at least 12 years.
The granite frames were made with Epucret and of portal mill design. They are a 4-axis design with XYZ linear axes and an A rotary axis. The CNC cannot be used as it required a web-licence to run cutting programs. Some of the fixture-tooling is Erowa.
The X axis looks to be around 250-280mm including a 20 tool Pick-n-place changer. The Y and Z are closer to 100 mm.
The spindles are liquid cooled Jager with 1333Hz (80,000 rpm).
XYZ motors are Nanotec, whilst the A axis is Berger Lahr.
Renishaw Tool Probe fitted.
Air pressure is 8 bar which I believe is for the tool change on the spindle.
They are single phase machines with 16 Amp plugs fitted.
The machines are on casters and weigh 480 kg each.
Width 80 cms x 100cms deep x 173 cms high.
I believe Stefan Gotteswinter (You-tube) did a conversion to a similar machine about a year ago. My plan was to replace the spindles with slower (~20,000 rpm) type spindles, remove all dental fixturing and splash guards,and fit a newer 4/5 axis control for horological components. I am now in the position where a house move with less workshop space is imminent.
Ideally I'd like to sell both machines together, but individually if necessary. I have no wiring documentation of any kind.
£500 each or £850 the pair. Offers considered.
