I have found a cylindrical grinder that has been sitting on a factory floor for about 10 years unused. I can pick this machine up relatively cheaply. I would only be for hobby use. It is a Jack Mill GU 750 FA.
I have no data on this machine other than what is on the name plate and the motor data plates. I know that it is a hydraulic machine because it comes with a pump. The table moves left and right freely. The control that moves the main spindle back and forth just spins but doesn't move the spindle at all. I assume this control is hydraulic.
The machine is covered in old grindings and coolant gunk. There is a lot of brown/orange corrosion but a good wipe with a rag reveals good flat looking machine surfaces without pitting.
The OD spindle turns freely. It ID was a bit seized up but came loose when I turned it with my hand. It still doesn't spin freely and feels like there is some kind of gunk in there? Could be crusted up grease or corrosion or something I don't know. Hopefully not grindings that have somehow found their way in.
The main spindle is 5hp 3 phase. Unfortunately I only have single phase in my shed. I would need to use some kind of VFD to power it. This may be a problem that prohibits me from buying this machine.
I would appreciate anyone's input.
