I have been running belt drive for a while, really nice. Quiet and a little higher RPM.
Too bad I dont have many good pictures of that setup. but I have a few pics of my new setup
The pictures are of my first setup, what you can see of it anyway.
Then pictures of the motor and mount I made, along with the cnc'd double pully I made at work.
I am now waiting for the 2 1/2" vbelts I ordered from mcmaster, they shoudl be here around wednesday. i set it up ontop with one 3/8" belt and turned it on very carefully, it sure is scarry spinning that spindle at 8000rpm
I turned it on slow and tried to stop the spindle like I can normally do with my other motor and it kept spinning!! I have about 3x the power and close to 3x the speed!
I plan on making a 2.5 and 3" pully to try out different speeds. a lot of what I do is in aluminum so I think cutting at close to 30ipm will be fun
How fast have you guys cut aluminum with your machines? I cranked mine up last night(turbocnc override controlles are really goofy), I had it cranking the part out at 10ipm and finishing pass at 18ipm taking .0625 passes without coolant.
You can see the fixture I made for this.
The fixture had a 3/4" hole in the center I carefully made to center with a indicator as my origin, worked great, the 2 bolts at the ends were for clamping the peice down and the holes in the middle area were for that too.
I first put the peice in, clamped it down, drilled my 4 holes, then screwed the peice down into the fixture. Then I milled around it and milled the center part out, and on the bottom peice I drilled and counterbored the holes that I mount it to the mill with.
I drilled and slotted the motor, that was a pain in the butt as the whole motor was like one big magnet, I covered it up real good, taped over everything. I did this by hand with a hand drill and then connected the holes with my RTX.
I have about 1/2" of travel of the motor, I need to do a few calculations and I should be able to use the same mount position for each pully size but it might be a squeeze.
Enjoy
