Looking at an older machine with a fanuc OM control on it. Looks like it is a 1991 machine. Currently we have a yasnak mx2 from 1987 and I'm very unimpressed by the control, if you feed at high rates like 108 IPM it seems to beat the ballscrews up pretty bad, very jerky motion. I try not to but it seems very easy to overload the control with moves and it will pause in the middle of a cut for just second while it waits on the next line or waits to process the next line.
Is this something I would have to worry about with an OM control? It looks like fanuc used the same basic OM control for a long time so I'm hoping that its a fairly nice control.
Also, how hard are parts to come by for a controller this old. Yasnak took a crap on me thats why I'm looking to upgrade machine/control.
Thanks,
AJ
