This thread is about converting a Haas SMM2 with a stock 10 tool umbrella changer to a 20 tool changer. Maybe it will be helpful for someone else thinking about converting their machine. It will probably work for the TM series machines too, but not those with the Next Generation control...I've heard the parameters are locked on those.
So, back in December of 2015, I was looking at buying a new Haas SMM2, but was on the fence about the 10 position tool changer...it seemed like too much of a handicap.
I distinctly recall asking my salesman at the time about the possibility Haas would come out with an optional 20 position tool changer soon...I also remember him telling me there wasn't anything planned for the near future...of course they came out with a standard 20 tool changer the next year...
Anyway, it's 2020, I've got the machine paid off, it's still like new and I've babied it all its life...maybe I could convert it to a 20...how hard could it be?
I started the project with most of the tool changer parts used off a VF2 (ebay). Unfortunately, it had the old style (slow) single pin geneva star, but the platter and other parts were good.
I also had an old 3D model of a SMM and a VF series from Haas. I used the models to verify the center-line of the tool changers on both machines and design a new mounting plate. Attached is a photo of the stock SMM2 the VF series and the plate I made out of CRS plate.
I went a little over-board on the adjustment slots for the dowel pins and ended up about a 1/4" lower than stock, but it worked out alright.
