Is a good rewinder, or will 'built-to-suit' at a reasonable cost.

There must be thousands of Hammond off-the-shelf transformers if you do not need multiple secondaries and multiple primaries.

What are the specific needs?

You can buy the replacement power supply on-line.

If it's running off 240VAC, you could replace it with a generic switcher that fits, or even a linear if there's room. 24V 2A5 out....

Hammond also winds to spec. Expensive, but I've yet to have a Hammond transformer fail that was operated within its design specs.

Not much you can't replace with the Hammond catalogue on hand and not worrying about extra un-needed windings.

I dont know what a CNC is, or what voltages are needed, but I was recently looking on Ebay for a small transformer and saw more heavy duty industrial ones than I saw the smaller ones.

If you know the xmfr specs you should be able to find one on ebay, I would think. CNC controls have been around a long time and all sorts of parts for them are on ebay. Eric
