Ever since I acquired a 4th axis and a Tool setter, my smaller VMC with a table area of only 20 x 16 started to get small. Once I had mounted the 4th axis and the tool setter - the working area was pretty cramped. I decided to get some sort of fixture plate that would allow me to mount the 4th axis off the table enough to get most of my working area back.
After looking around for a couple of years on eBay, and finding no joy for a used plate (If my mill happened to use Haas spacing - I might have found one). I did happen to see a listing for a new plate from Saunders Machine Works - saundersmachineworks.com. (They also run the NYC CNC website www.nyccnc.com that has lots of great info). It wasn't cheap, but was specific for my machine and was exactly what I wanted.
I had great feedback from NYC CNC about some questions I had re: mounting, cad drawings, etc. and the plate arrived in about a week. It was nicely crated up and very exciting to receive.
One thing that did come up - they sell plugs for all the holes so swarf won't get down in there. I misread the web page and didn't order enough for all the holes. (I asked SMW to clarify the info on the page so it's clearer how many you'll need.)
All in all this is going to be a great upgrade to the mill, giving me many more set up options. Who knows maybe I'll start using dowel pins for alignment?!?!
