Thank you for suggestions! Just to clarify a little bit of what kind
of machine is that - here you can see backside of the machine:

In my case the main problem are the rails along X axis (length of
machine), where all that Y axis frame is mounted (in that picture it
is retracted to left side, it will move all the way to right side, it
might fall into category of 'cantilevered frame') . So taking the
rails off the machine is definitely not a thing I want to do. Y axis
rails are in much better condition and Y axis ballscrew also is better
(X axis has rack and pinion drive)
The size of the rails is approximately equivalent to Hiwin HGR35.
Unfortunately I did not notice the condition of rails when machine was
loaded, so it was moved half a way to make room for placing the
control cabinet on top of the machine frame. It seems to me that
cleaning the rails AND injecting lots of grease in the bearing blocks
is mandatory before attempting to move it again.
From all the responses I am not sure I understand completely, what is
'elbow grease'?
The mythical grease you would use for arthritic elbows and such since
this looks like a lot of what we've jokingly referred as flying a--h---s
and elbows. I see from the pix this looks like around a ton of moving
weight. Removing the rails for replacement would no doubt need an over
head gantry style crane.
This might be a "slanguage" saying that has not made the translation
barrier cross to your native language. As a one language old Iowa farm
kid, I first heard it in about 1940.
Take care & stay well Viesters.
I would use something like this for the bearing blocks:

I've had good success with fine scotchbrite and WD40/AC90/Duck oil or
other light oil spray. It seems to do a pretty good job of knocking off
the rust without affecting the metal. I find steel wool doesn't last
very long and leaves bits of steel wool everywhere which is a pain to
clean up.

Hello!
Last year there was a chance to acquire Biesse machine for a a really
low price so I surprised myself with pretty large and heavy Christmas
present. Just put it in the workshop (where heating is not yet
present) and was waiting for a warmer weather to start retrofitting it
with LinuxCNC.
Since this machine has spent at least several years in a shed - roof
above it but no other protection against outside temperatures, I did
not worry about adding one more winter to it.
I have 2 questions:
1) are there any recommendations for outside temperature when trying
to connect it to power? I want to see the status messages on
servodrives - hopefully they are good (I have done 4 similar retrofits
so I feel familiar with those old drives).
2) my main problem is the rust on linear rails. what is recommended
procedure to treat this?
Here is a picture that show the extent of the issue:

What I did is brushing it with a piece of steel wool moisted with oil.
I am not sure that it is sufficient so I would appreciate any tips on
how to treat them.
