Default part out HNC - ping Gunner

I'm making room for the big backhoe by parting out a couple boneyard
machines...

I moved the hardinge HNC into the shop and just got the headstock and
spindle motor removed.

Next chore is the carriage. I'd like one piece if possible. can the entire
unit slide off the dovetail? After a break I'm taking all the stuff off the
tail end hoping this will work. Suggestions appreciated.

Karl

Yes, you can take the carraige off by sliding it off the end of the
dovetail. If you have the coolant pump, you will probably have to
remove it first. Pull the gib wedge from the slide, then remove the
slide control box from the end of the slide (sometimes the wires may be
long enough to hang off the end of the tray..sometimes not) and simply
crank the slide off the end of the dovetail.

Be SURE to have a die cart/forklift or similar parked at the end of the
dovetail...because that slide weighs about 150 lbs with turret etc etc
and you will likely drop the heavy ******* if you try to remove it by
hand.

One step that will REALLY help..is to remove the bolts that hold the
front of the slide on..the portion that has the cranks/clutches on..and
pull the last two out but for 3-4 threads and tap them until the entire
assembly comes loose and drops loose, then carefully remove the last
bolts and drop it into the tray. The front controls under the slide
are bolted AND dowel pinned, so you may have to tap a bit, but its
obvious when it comes loose and wont take much tapping.

This also helps get the slide free as some..some of the HCs had stops on
the track under the dovetail.
As a matter of course..I always drop the front of the slide..get all
that stuff out of your way..then slide the rest off the dove tail.

Oh..slide motor wiring will need to be either cut, or disconnected from
the control box at the right end of the slide. Dont be surprised if the
wire is hardened to brass like rigidity. Simply cut the wire, as you
really should replace it later if reusing and its common multiconductor.


Id strongly recommend keeping the entire slide, or parting it out on
Ebay, if you are scrapping the machine. Btw...if the spindle bearings
are in good shape..the stripped HC is worth about $500 to anyone who is
looking to build an OmniTurn retrofit machine.

They are VERY accurate and very rugged and more than fast enough to make
money with.

I'm not following all of this. This is a CNC machine with ballscrews. Are
you talking about an HNC here? I'm not seeing cranks and clutches.

Tis a bit of a shame to part this old girl out. I got the running machine
cheap with a Camsoft license and a ton 'o tooling. I took the control off
and a few solenoids and stuff from the air control cabinet. I need to
rebuild the air turret on my running CHNC - I'm not sure if many parts are
the same though.

How is the slide attached? I got TOTAL grundge looking up from inside the
cabinet and can't see a thing. Must be held on by magic.


Anyway, I'm picking as many parts as I can easily remove and tossing the
carcass. I know I only need to use a couple to pay for the whole machine.
I'm sure you've seen hardinge replacement part prices.

The CHNC slide comes off pretty much the same way as I recall. Ive only
serviced a few of them and quite some time ago.

Carbonized swarf grunge. Ever pull an automotive intake manifold?
That stuff, only it's softer there since there is no stranded swarf to
hold it together.

I'll bet a hot water pressure washer would rescue you, Karl.

I found out about this model the hard way. I thought I was buying a CHNC.
Turns out its an HNC. Looks like hardinge's first venture into the CNC
world. They took an HC, fitted it with ball screws and an air turret and a
total POS control. A year or so later, it was upgraded and changed to CHNC
with an allan bradley control to start (many others later). One fine
machine, as you know.

Anyway, the HNC has several parts in common. And a lot more that look the
same till you try to swap (bet they fit the HC). The CHNC machine weighs
about double and the extra iron isn't going to waste.

I gave up on the carriage for the moment and I'm stripping everything below
the table.

Have you ever pointed a hot pressure washer straight up into a filthy
cavity? I don't need the slide that bad. This is one dirty job as it is.

Sounds like a modified AHC

Slide comes off as I indicated, more than likely, with the exception of
the servo on the Z axis.


A big DOH! when I seen the problem. I loosened the adjusting wedge all the
way and the carriage slid right off. Got the machine stripped of most
everything of value. Now, all the parts will fit in an apple bin and go up
in the pallet rack storage.

A big plus to a machine that ran oil, no rust anywhere.

Be sure to Spray the parts with LPS-3 or something similar. Many of the
cutting oils are water soluble and will wash off surprisingly easy. Come
back in 6 months and be totally shocked to find them covered with rust.

Clad to have been of help.

Don't you have tubing, a bender, and ten minutes? 90 degree bent
washer nozzle keeps you out of the "action area".

Do a one-arm curl to right the little two ton lady after you're
