A couple of examples. The knee and quill on a milling machine. The head ram and table Y axis on an old Gorton mill.
Can LCNC combine the two motions that are in the same plane to provide a greater range than either alone? This would be especially useful on Bridgeport and clone knee mills that usually have a quill travel around 5 inches. The Gorton is an old linear ram hydraulic True-Trace dinosaur. For the Y axis it moves the ram and head in and out, but the table also has a long manual motion with an ACME screw. With both combined it looks like its total Y travel would nearly equal its X travel, which is all hydraulic plus a tiny 5" manual range that was apparently used to fine adjust for starting to trace the pattern. Gorton billed these as being usable as a full manual mill... Given that the Gorton's head has no tilt or nod, it'd make a quite nice CNC mill, no need to ever tram the head because it can't get out of tram. Probably best to replace the hydraulic cylinders with ballscrews, unless there's a way to precisely position hydraulic rams without direct machine position feedback (linear scales). In any case the huge hunk of iron would have to come to my shop extremely cheap. If it was the somewhat later version that used hydraulic motors with chain drive to screws, I'd be all over that. Much easier CNC conversion. ------------------------------------------------------------------------------ Rapidly troubleshoot problems before they affect your business.
