I posted this question over on the Deckel etc. euro machine forum,
http://www.practicalmachinist.com/v...a-em-825-built-u-s-any-info-out-there-276271/
but not getting much response. Since the machine was apparently marketed through Bridgeport (according to a metal tag I found on it), the
guys over there thought someone here might know something, or about the history of the link between the companies.
I'm guessing it was built in the 1960's or so, and specifically for export to the USA, since it has:
1. inch-reading dials and leadscrews
2. that Bridgeport nameplate
3. hardware, clamps, gib adjustments and so on all have metric heads, but _inch_ threads (!?!).
4. a 115V single-phase two-speed motor (definitely original)
Item 3 is strange no matter how you look at it. Maybe the Swedes wanted to use their metric wrenches for assembly, but the US service department insisted on stocking only inch threaded fasteners?
In any case it's #4 that has me stumped. There's not much about these mill/drill machines on the web, the lathes.co.uk writeup being most of it. That said, every other example I've read about is 3 phase, typically 415V Y. The motor is integral to the head; to run on 115V single phase, this one must be radically different. It has a couple run capacitors mounted inside the column but the wiring is a deep mystery.
Arboga mainly made drill presses, evidently still does for the Jet brand; but I wrote them, and apparently nobody over 30 works there anymore.
Any illumination or speculation would be greatly appreciated. Thanks for reading,
Mike
