the RF-25 is not a bad mill. however i find its small size limitting to what i want to do. i am converting it to cnc because thats what i have. in retrospect i think i would have at least bought and RF-31 if not the rf-45 the dovetail column mill. i don't have a problem with the head not being fixed its primarily in the table travel. i get 20x6 and will will be maintaining this after the cnc conversion, i am building an offset motor mount so it doesn't limit my travel.
those ball screws look to be the same inexpensive ones that everyone else sells too. basically i would get them from the cheapest place. roton and mcmaster carr carry those too and i think grainger does too. |
