Clearly the machine was not measured.

Or not measured correctly... If its a new machine and clearly out of spec then I'd return it under Sale of Goods Act 1974 as 'not fit for purpose'. If it was bought 2nd hand then you don't have much option, but check first that there's no swarf etc trapped in the slides.
