Damaged CMM Machine

Your company might have just inherited a brick.  The second pic shows a darker spot dead-center in line with the scrape. 

I'm guessing something really heavy fell upon it and dented the ram, producing raised surfaces that weren't corrected.  They kept running the machine, and the machine's air bearings probably went haywire trying to ride over the raised edges, producing the other scrapes. 

Once that anodized finish is worn out... there's not much that can be done to get it back online. 

Maybe Hexagon can replace the entire ram assembly and air bearing pads... but it's not going to be cheap.  We had an old DEA Scirocco which was run on low air pressure (switch wasn't appropriately adjusted to shut off when lower than 65psi), it ate the x axis bridge, and we actually had hexagon come out and stick the proverbial first nail in the coffin.  There was nothing they could do to repair the x axis, but maybe they CAN work on the ram, since it's so common and small.
