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: https://wta.hoechsmann.com/en/article/72463/biesse_rover_322.html#gallery-4
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'? I would use something like this for the bearing blocks: https://www.qualitybearingsonline.com/gadus-s2-v100-2-400gm-hi-performance-m-purp-grease/ Viesturs pirmd., 2024. g. 11. marts, plkst. 14:59 — lietotājs Les Newell (<les.new...@fastmail.co.uk>) rakstīja: > > I've had good success with fine scotchbrite and WD40/AC90/Duck oil or > other light oil spray.
