Wow I did not realize you were trying to drive the high speed engraver off the main mill spindle. Almost 4:1 speed increase with a single belt is pretty optimistic. Going the other way is a whole different animal. If you are now thinking about using gears, you would be well advised to seek out a planetary set. Consider yourself so advisedOk I will take that onboard Now what about this idea, this was actually my first but it ended up going by the wayside. I have some small Alpha in line planetary gearboxes that are meant for servo reduction. I was planning on driving it arse for tit and then I discovered the Input (which would be the output) relied on being clamped to the motor shaft. No probs I thought, housing, angular contacts and job done. I then looked up the spec and it says 6000rpm input speed so I decided against it. I am thinking it may be worth a shot, have a couple of angular contacts and would be simple to make up a housing and shaft. If the box screws up its no big deal as I got 2 of them for £12
In my setup, I am shooting for 40k to 50k rpm, but I'm starting with a pre-balanced 30,000 RPM tool motor.
In any case, good luck and please keep posting your results. This is interesting to follow.
Sorry to be dense, but I'm not following this at all. How do you engrave at 1,475 RPM
