Just been contacted by the shop floor to have a look at our Hurco mill. They are milling a casting where they have to be very flat. Now they either get it flat with a rough finish or get a good finish but not flat. We noticed that in the desirable milling direction that the back of the tool does seem to rub. Straight away this would say to me that the spindle or the bed is not square. Upon checking this we found them not to be, now the question is does anyone know what the tolerances should be for this machine as I have no form of manual or paperwork to consult.
Thanks for your help in advance!
