I've just purchased an old but good Jones and Shipman grinder. While stripping it all for sand blasting and repainting, it looks like a great candidate for CNCing. CNC the headstock rotation and the grinder forward/backward travel.
See here (Not mine) http://www.excellmachine.com/products/cylindrical-grinders/ The headstock only needs to turn at maybe 10 RPM, so a 300 - 500 watt motor should do the job, as the grinder only takes very small cuts in the part. The main grinding head (80KG or so) will need a bit more. I can still use the automatic table travel and use a micro switch to increment the grinder travel for longer parts. I would like to eventually grind engine camshafts and I think this will do the job. Any comments ?
