My application is for a Rotary Table CNC grade. Looking for a way to cut a 6" (approximately can be plus or minus) wheel. And a way to cut a Worm.
I am putting a 1 KW AC servo on it, so it will need to be strong, but accurate. It is a custom application but for a custom CNC machine.
I would like to be able to cut/make my own, since I am interested in learning the technology of this. I have a Mill and Lathe to cut with.
I don't mind even if I would have to make a single tooth cutter, or buy a Involute cutter, but a Gear Hob would be the best, but they are to high. I have NOT had a lot of luck on finding resources (books, how-to's, etc.), on how to make your own Gear Hob. Obviously, this is a closely guarded secrete, or, I just don't know what terms to put into google.
Harmonic Drive: Yes, I had thought about these, but they are also, far to expensive. Don't do ebay on stuff like that, since you don't know what your getting, nor do you get any kind of warranty on the part. If it goes down, then I am really out of luck.
I have never cut gears of any kind before, so, in essence, I am a total numb-skull in this area. I have looked on the net for Worm/wheels cutting, and have seen the "I used a tap" etc. type, but none for larger/stronger gears nor precision stuff.
Sorry, not trying to be difficult, and I may be having a "Pipe Dream", on doing my own that is affordable to make, and precision as well..
