I purchased this machine a few years ago for a production job that never materialized. I recently replaced the crossfeed scale, which was acting up, with a new Sony scale. The machine was also serviced by Okamoto last month and the only thing they found wrong was a sticky limit switch, that they then replaced. The machine is in awesome condition and under power for you to inspect. It is wired for 430 volts but I have a step-up transformer, that I purchased new, so I could run it with 220 volts. The transformer is included. It also has a chiller and a coolant pump that comes with it.
