"infinitely variable electronic controls" for spindle speed and sliding feeds- down to 0.0001 . i don't
typically turn at a .0001 feedrate.... repairing that type of arrangement could be "sophisticated" at best.
just want to know if i should go any further with the sale.
Barber-Colman certainly
did buy the Hendey line of "lathes and shapers".
Hendeyman would know how their "end-game" went down at the time of transfer. Prolly already in PM annals?
But I thot B-C was where the design that would have followed the
Rivett 10X0S wandered-off to?
You had:
10EE, 13EE / 1000EE - NO relation.
Hendey T&G with ISTR 3 different Drives, one that include a Reeves, another with a Fairchild or Rexnord version of a PIV Werner-Reimers, and one that was "electronic". Trboatworks rebuilt his nicely - PIV drive included.
Rivett 1020s / 1030S "compounded" Reeves.. but not-only. They had another drie similar to 13EE or 1000EE?
Nebel Microturn? We've only ever seen 2 on PM that I recall, one of them a member's personally owned? Another a plant selling it off? But again no relation.
Sidney? Pass. I know not about an electric drive.
Only one I ever looked at was in "Little" Washington PA, easy one-day go fetch. I lived there as a kid. About 1949. It was the "semi-conventional" "Herringbone" and waaay too big for my needs OR space. 22" or 24" and not a short bed, IIRC?
That's just the USA.
Otherwise, it's just a "technological era" thing as to old DC or AC drives being problematic.
Ex; if one had the second-generation Lodge & Shipley "AVS", it had a sophisticated for its DAY variable speed inverter drive. Problematic in its Old Age? Assuredly!
But.. nowadays we just call those "VFD". And they are all over the place.
So if the AC motor is good? One guts the old inverter drive and replaces it with a MODERN VFD. 1-P input OR 3-P input. Easy one-box drop-in.
3-P AC motors aren't hard to find, either.
IF.. one had the FIRST generation Lodge & Shipley AVS? DC Motor. Early-days DC Drives. Same deal. Gut the wiring. Drop in a modern "4Q" DC Drive 1-P input OR 3-P input.
Lots of choices as to the electronics. Finding DC motors might not be as easy. No shortage. They just COST a lot more.
Even so, it should be obvious that if one went to 3-P + VFD, the factory has already done that, so you won't really have an "orphan" that has to be re-invented, all alone, and in the dark.
That was L&S.
B-C? Much the same. Can't preserve? Convert.
Main thing is the costly spindle bearings.
Ways and cross? One can compensate.
Gears can be made.
Uber high-grade bearings?
Never cheap!
The electronically variable feeds? Close cousin to any other electronic feed as far as to
function, Hardinge onward.
How hard can it be to adapt off the mill traverse or CNC world if it cannot simply be repaired or upgraded?
Not hard. Not hard and not expensive, either.
We are surrounded by choices of salvaged gear in good condition to apply or re-purpose.
It need not look identical to OEM.
So long as it is useful? It need not even FUNCTION identically to OEM.
Bearings? That would be my show-stopper.
Fortunately, one of the easier things to check.
