Okuma LCS-15, to buy or not to buy

Hi all,

I am thinking about buying a second hand 1995 Okuma LCS15 with OSP700 to upgrade my 1986 Ikegai FT-20Z with Fanuc 11T. Overall it looks like a nice compact machine which will save me value space in my small work shop.
I know the obvious things to look for when buying a second hand machine, like spindle wear and back lash. I was wondering if there are particular weaknesses, inherent to this type that I should look out for.

Greetings and thanks in advance.

Do you mean LCC15?

Our LCS15 with OSP700L is working well and is a good machine.
Yes it is a LCS15.

Thanks for your quick answer. It looks like a very rugged and compact machine indeed. I have an appointment with the re seller next week. I am taking a clock gauge to do some basic backlash measurement. The OSP700 will probably be a lot more modern than the Fanuc 11T. How user friendly is the OSP700 do upload G-code?

It's just perfect. Check the capacity of memory available.

The 700/7000 is light years ahead of an 11. Even the 5000 was ahead of the 11, both out at the same time. I'd look in to converting the floppy disk to the USB if you plan on using that. I set up RS232 on our 7000 last week, only took about 30 minutes.

Thanks for the info UTT.

I got the machine up and running now, still need to check the RS232 connection though.

I saw the machine has got a coarse read-out of the spindle orientation. It is called CD on the screen. Is it possible to do a coarse spindle orientation on the LCS15, for instance to broach a keyway? If yes, you would not happen to know the instruction for that?

The machine will NOT be able to perform slotting based on the CD axis position UNLESS it has an "M" spindle associated with it. i.e. you can also do milling work.
The reason is that there is no spindle clamping mechanism available to keep the spindle oriented in the desired position.
The CD position is only used internally for things like screwcutting, not sure why Okuma even display this value as it is largely useless information.

Thanks for that very clear answer brody. I will have to do the slotting work separately on the milling machine. No big deal for small series.

I have LCS-15 ser number 0292 build in 1995.
I am searching electrical diagram.
Can I contact with you about this subject?

Hi there
I can help you and mail you a copy of mine, please contact me:

Thank you for your proposal. I had it (the electrical diagram) one year ago.

Dear Sir,
I have the Same Okuma, But I need the Floppy System and backups !!

Would you help me? Make an Image Or
...

Please Contact me, as Well

Warm Regards :)

Hi!
I have only 4 floppy (http://www.cnczone.com/forums/okuma/...-software.html)

The machine may have spindle orientation. You can use the M19 command to find out. If it says unusable M-code then you do not have the option. UTT is correct in that you probably would not want to broach with the spindle without some sort of braking mechanism. Some had "pin style" spindle orientation, but it was a pretty rare option so I'm guessing that yours does not. With that option, it would be possible to broach. Also if the material is soft enough, electric orientation may allow you to broach, but do so at your own risk. The spindle may have a tendency to move. Pin or brake style is recommended.

Best regards,

Thanks for that answer OkumaWiz. I know for sure now I do not have the option since I could not find the mechanism for it.

But I have a far worse problem with the machine right now. I posted in another thread about a CPU error I am having. I am an electronics repair technician but if you can point me in the direction to look for my problem, that would be great.
I posted the fault description in the following thread: http://www.cnczone.com/forums/okuma/331684-forum.html
