I started pulling stuff apart on the bostomatic today found out some information on the encoders and spindles.
The encoder is a encoder products company 755a it is 5000 cycles per revolution. Quadrature A&B channel with index. Line driver output, max frequency 200 kHz <= 3000 cycles per revolution. There are 2 spindles on the machine. Main spindle is uaaska-04D looks like its 1500/8000 rpm rated Secondary spindle is the precise corporation sc82. Spindle is 10000-40000 rpm rated. There are linear rails on all 3 axis. A 15 position tool changer for the main spindle. I think the machine should be really nice if i can get it running. Also if anyone has ever heard of or knows Barry Tognazzi or Gary Wells both from Massachusetts I'm trying to get in touch with them. They were part of a company that specifically retrofit Bostomatic machines that was dissolved in 2018. I hope to get some better info if i can get in touch with either of them. Any suggestions on best way forward is appreciated. Trying to retrofit the machine on a fairly tight budget.

Everything else sounds like a simple retrofit, DC servos are relatively easy. Do you have the power supply? If so, what is the actual output voltage? The Pico servo amps are close: http://www.pico-systems.com/pwmservo.html but may come up a little short if the actual power supply voltage is 180V. The 7i29 from Mesa http://store.mesanet.com/index.php?route=product/product&path=83_90&product_id=141 also comes in a little low on voltage. (Note that you can run two motors from each 7i29) If you don't have the DC power supply then perhaps you could look at AC input drives, https://www.a-m-c.com/product/ab30a200ac/ might be an option. But AMC make so many drives it's probably best to actually talk to them. -- atp "A motorcycle is a bicycle with a pandemonium attachment and is designed for the especial use of mechanical geniuses, daredevils and lunatics." — George Fitch, Atlanta Constitution Newspaper, 1912 _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
