Re: Help needed to identify my Mill
The base machine has the appearance of being made by Topwell, a manufacturer of high quality machine tools in Taiwan. There were many container loads of those machines imported in the 80's and then the CNC hardware was installed by the importer in the US. If you bought a container load, Topwell would put any name you wanted on it. The badge normally is above the spindle speed dial, but it looks like yours is missing. Most of the machines I have seen had Anilam controls on them, never seen one with a General before. That's a first for me. Most of those importers are long out of business, but you can still get some parts for the machines.
As far as the controls, good luck. I wouldn't even mess with 30 year old controls, but I have a pretty low tolerance for antique controls, although I am still using the 30 year old DC servos and drives on my machine with modern controls. Modern control systems are cheap and readily available. I would look at Dynomotion, Centroid, Mesa, or CamSoft. If you should want to replace servos, then DMM servos and drives would be my first choice.
