RE: Hardinge Lathe - PixMan - 11-24-2012

I'd LOVE to get my hands on one of those HLV-H lathes! I worked at a medical instrument/fiberoptic surgical lighting manufacturer who had one and I used it a lot. I just loved the way the threading worked. If you can afford it, get it! Just don't change that smooth-running motor unless it's already cooked beyond repair. ;)

Greg,

I wouldn't mess with the motor either. Hardinge put a lot of engineering into that drive and I doubt that you could slap a commercial motor in it and get the same performance. I haven't looked at mine in a while, but the motor itself may be part of the variable speed and braking mechanism. I'm away from home right now, but I'll take a look at it when I get home. If you could figure out an economical way to generate the proper voltage, that would probably be the better way to go.

Beware of those government auctions, a lot of that stuff isn't properly stored. In fact, a lot of it just gets put outside until it can be disposed of.

I'll do some checking on Monday for prices on a step up transformer, would be the best way to go. What voltage is yours Tom?
This one looks pretty good in the photos, would have to see it in person, the paint looks perfect and I doubt the government has painted it. Has the same dry green residue on it that my Cochester from them had, must be some weird cutting fluid they use that dries on, forget what I finally found to remove it.

Wait! our government (cough choke, spit) hasn't progressed yet to intentionally destroying assests they'd like to sell.

Greg,

Mine is 208 3 phase.

Here is a pic of that Hardinge that was left out in the rain. The auction has closed so the link to the full size pic no longer works, but it's probably just as well. All of the steel surfaces were HEAVILY rusted, including the ways.

Ouch, this one is still in a warehouse.

RE: Hardinge Lathe - stevec - 11-25-2012

Ugh! That's criminal.

Just another example of "Clueless" Government employees!!

More "Zombies" of the White Collar Crowd!!

Greg,

Here are a couple of pics of the motor in my HLV-H and keep in mind this beast is rated at one horsepower. It does not appear to be part of the variable speed or brake as I thought, it is just bolted to a cast iron base. I think if you wanted to replace it, you would need to make a heavy flywheel to simulate it's rotating mass to maintain the finish the Hardinge is capable of.

RE: Hardinge Lathe - f350ca - 11-28-2012

Thats an interesting idea Tom. The added momentum at the motor would make the difference between single and 3 phase, but wouldn't make up for the extremely well balanced armature that Hardinge uses.
