Need Help!- Hardinge Omniturn Lathe

[K_Labs]

Hey I just got one of these and I want to know what I'm getting into. It's a hardinge with 5-C collet omniturn retrofit w/ a full enclosure I don't know much about it. I have some CNC training from NTMA but that was a year or 2 ago. They mainly focused on HAAS and I have never used a Fanuc control. Can any1 tell me the difference? I'm baffled. I also noticed there was no visible G54 in the manual. Why is that? It has a gang tool. The programming looks a little different from what I learned in school. Any help would be greatly appreciated.

Did I post this in the right section or should I post in the programming section?

Now I just have to get this thing right side up. LOL.

I just started running 2 Omni's, there is no G54, there is one Z-zero, for each tool, it is not a fancy machine, it is dated, the screen is too hard to see, it has only a few options. With all that said it is great it makes good parts all day, and all night, and it is really easy to program. All the tools just need to be touched off individually on the face of the part, and you're good to go.

That's awesome. I'm happy I actually got a responce on here.

I Just bought one a few weeks ago. Hardinge AHC Omniturn Retrofit- the same machine.

I've been using a Hardinge CHNC with a Fagor 8025 retrofit for the past 2 years. I now do program editing in KipwareT, and send programs back and forth from a PC with WinDNC. Both softwares are excellent and work hand and hand.,

The g-code is very similar between the controls and I believe Kipware will translate the differences, and Kipware has DNC to send to the Omniturn. So I will be controlling both machines with my PC.

Awesome thanks for the heads up. We just picked up a bar feeder last week. We haven't even hooked up power to the hardinge yet although I did power up the OT control panel and messed around a little. I was wondering if it is possible to make the collet open and close from a program or do I need to do it manually?

Having the collet closer powered through Gcode was easy with my CHNC (mach3). I dont know how to set in up in an Omniturn control, but I would think Omniturn would have a relay output for an air collet closer.

[JP Hardinge]

You bet if you have a power collet.

My recently aquired Omniturn came with this beauty-

Nate-

I've seen where you have done a lot of tear down work on these CHNC's.

Can you tell me which air/lube line sends lube to the ways and ball screw on the cross slide? I really need to check mine and make sure it's getting lubed on my CHNC properly.

The ways have those nice molded wipers and hardly any lube shows up on the ways. They are slick and not dry. I think the wipers do such a good job, it holds all the way lube inside. My ways are smooth,.

Sadly, I dont have me CHNC running the original air/timer actuated lubrication unit (rolls of the tounge dont it...)

I can tell you that the X/Z axis ways AND the X axis ballscrew are oiled by the 3 lines that feed a small (deck of cards size) black metal box on the back underside of the Carrage (moving Z member) This small black metal block feeds channels that go to the X ways and the Bed (Z way) their is one tube that is a pass through that feeds the X ballscrew nut through a TINY barbed hose fitting.

Since I dont have the original lube setup, I hooked up a Bijur Pull-to-lube unit that feeds lube through the three lube lines that go into the metal block thing.

Loosen the metal block thing and see if lube pours out. Also check to see if it is filling.

The second Carraige assembley I bought for spares had the Z ballscrew also fed lube automaticly. My CHNC has the Z ballscrew lubed with a small oil cup entering a resovior (ballnut mount)

Hope this helps...

Nate.

Thanks Nate- does help.

I will check those. I know the 3 lines and block is there. Also, I know lube is getting used up, by having to add to the reservoir. Not much (maybe plenty), but it's getting used.

Do you know what I would need to remove to see the X ball screw, and check for lube at that point?
