Hello all, I have a Hardinge HNC which I am thinking about converting to EMC. It was working very well for the previous owner, so I am concerned about making sure that if I make the conversion, that it works just as well or better, in order to justify the conversion. Does anyone have any experience with EMC with the HNC that they would like to share? Should I consider using the existing resolvers as opposed to replacing with encoders? The PLC feature of EMC should be able to handle the turret, the two speed spindle, collet closer, bar feed, parting attachment, coolant, and lube system. I am planning to remove the variable pulley drive and use a VFD with the existing two speed clutch system instead. I believe the servo drives have +-10V analog input so Jon's PPMC would be appropriate? Apparently, the turret position feedback is a three bit binary value, so I will need a binary data input somewhere. Anything else I need to consider? Thanks.
