Has anyone retrofitted a 4 axis lathe?
« on: November 17, 2009, 01:36:53 PM »
I have a cincinatti 1410 that I am thinking about retrofitting. It lost its programing in the Fanuc controller and I am not having much luck finding info on how to reprogram it. Called the magcincinati they said they would try to find a manual and that was the last I heard.
So I have been thinking about using a DSPMC/IP to give me analog outs for the existing DC drives and spindle.
Then all I would really need to figure out all the IO and make both the dual turrets work. Then figure out how to tweek a post processor for a 4 axis lathe.
It is no small lathe it weighs over 20K. 30 horse spindle.

What do you guys think? Ripp it apart and make mach control it or try to fix the Fanuc stuff?
They call it an acramatic control but the work is being done by Fanuc.
Thanks

Do you have a pic of the lathe, I did a google for it and just came up with shears :(

Hello Hood,
Glad to see your still on here,

It is about exactly like this one:
http://cgi.ebay.com/Cin.-10-Cinturn-4-Axis-Univ.-Turning-Ctr.,-Series-1410_W0QQitemZ250527872512QQcmdZViewItemQQimsxZ20091110?IMSfp=TL091110181009r6311

Mine doesnt have a tail stock. It looks like a real stout and well built lathe and the controls would probably work well if i could figure it out.
Four axis because it has dual turrets that move seperate of each other.
Thanks

  8). That is one mean piece of iron. 8)

As far as fixing the existing controls goes I have no idea.

I will tell you that if you want a new controller that will run Mach3, the DSPMC is a nice choice. I have one running my BTC-1 mill and have the other going onto my Tsugami chucker lathe conversion.
I will be attempting to integrate the tool changer which is similar in style to one of yours and I don't see any insurmountable obstacles. The lathe threading is working on the DSPMC.

If you have more questions on the DSPMC feel free to ask, If I don't have the answer, Rufi will chime in when needed.

We never have the time or money to do it right the first time, but we somehow manage to do it twice and then spend the money to get it right.

Nice looking lump of a lathe, thats the kind of machines I like :)

If you could get the original parameters then that would be the way to go as integrating with Mach, although certainly doable, will take a bit of work and you will need custom macros for the toolchangers and possibly a PLC depending on what I/O the DSPMC has, not difficult but takes time and thought.
Programming may be the headache but if you have CAM I am sure you could adapt a post processor to suit or you could even adapt the wizards in Mach for your dual axis setup.

Thanks guys, I have been looking for some manuals but they are pretty hard to find. I think I will e-mail the gut on e-bay and see if he will sell me some copies. If not I will get some electrical drawing and start ripping it appart.

I hate old original CNC controls because you almost have to get a tech to tell you whats wrong. Not like mach 3.

Keep us updated whichever way you go, it looks like a really nice machine :)

The main problem you will have with a 4 axis lathe is that mach blends all axis motion together, you need to be able to run each turret separate, this is not possible at the moment so one turret can not be in rapid and one cutting so you loose the benefit of the 2 turrets.

Thanks for the info Graham. I might have to just use one turret then if it is going to cost me too much to get the original going again.

You could still use both turrets, just not at the same time.
