Good day lads. Got a question. I’ve got a Hardinge Chnc II chucker lathe. I would could call Centriod direct but felt my question would be answered better by people here that have had their hands in one. The tooling rotary is air operated. Can the All In One software handle this type of machine?
Thanks, Bob L

See https://www.centroidcnc.com/hardinge_chnc.htm

and also:


There might be some work required to combine the most recent CNC12 / Allin1DC PLC-program features with the existing logic for the Hardinge turret and other accessories, but there are really no unsolved problems here.

That one is running with Allin1DC and CNC11.

Thanks for the input. That machine sounds like it need new spindle bearings. This is interesting since a CHNC has two huge cabinets that could be reduced to 36X36". I fixed to rehab this lathe as I acquired new balls and screw before they became obsolete. This is one of my babies. A quarter of the floor foot print of a slider. Bob L

The noise is from the portable air compressor. I doubt you could hear the spindle bearings over it, even if they were bad...

Yes, a retrofit control based on an Allin1DC would easily fit in the ca. 30" x 60" cabinet on the back of the headstock.

I was just joking around. My point was the noise level of the shop. That video has me all hyped up now. Got to assume that whole strip of Mylar crap switches goes away with the conversion. Sounds like a whole lot of fun work. Bob L

You've lost me here. Are you referring to the turret position encoder? Or to the switches such as the X limits, spindle lockpin sensor, cutoff slide up/down, etc.? Or something else, maybe inside the old control cabinets?

My CHNC was produced almost at the end of production. In front of the door there is a table of switches. I call them Mylar crap switches. This stuff was destine to fail before it left the drawing board. See picture. This stuff was all the rage in the 70s early 80s. My case back hoe had 10 toggle switches on the dash board to replace this stuff as each switch failed. So many I finely had to label them. Bob L

Most or all of those functions can be provided with the Centroid jog panel keys.

The "Aux" keys in the upper right can be custom-printed as needed; or if you opt to just use the "virtual control panel" on a computer monitor, then you can customize the graphics yourself.

So I got assume that the programing for tool changer just fires the air solenoid for the turret?
