    LB15W supspindel program question

    Good morning,

    I have a LB15W with a OSP5020L controller. have never used the subspindle, but have a job for it now.
    As I can't program the sub in IGF I have hand written a code by trail and error.
    I have the program almost complete but I have trouble with the end of the program on the subspindle.
    After the last deburing routine, I travel the turret to a safe location and after that I want to stop the subspindle to stop turning.
    I have tried all possibilities I could think of, but none of them works.
    M05 give'd fault code 427-alarm B M-code unusable
    If I put a G140 in front of the M05, same alarm
    If I give a SC=0 command, it stops the spindle form turning, but the programs stays on that line, probably waits for a readback from the spindle speed of something.

    Any experts out there who can help with this ?

    Kind regards,

    Peter from Holland

    427 Unusable: M-code

    If I give a SC=0 command, it stops the spindle form turning
    it does not use S0, but SC=0 / different syntax

    I tried S0 command on my 5020L before writing forum.

    On one very old machine the used M148 and M149 to run the “pickoff” spindle with I believe an SB=500 command. But only 1 LB-9W used a M123 SC=500 as far as I know and then everything went to G141 with M3,M4,M5. What you describe I’ve never seen on any sub spindle Okuma. (And I’ve been on them all)
    Maybe try M125 like the LB-9?
    Are you using single block so that you are sure the M5 is causing the alarm and not something it is reading in advance? It’s not normal for G141, M3, and S500 to work and not the M5.

    Can you show us your exact code?

    I’m in N America, so can’t say what made it to Holland…

    Re: LB15W supspindel program question

    Hi Guys,

    Little steps forward between jobs

    I Bought a original manual off ebay, with all the code's in it.
    So that make's it a lot easyer.

    It seems that M122 is the right code to stop the spindle.


    As for now, I made a program in IGF, and changed al the Z value's to positive offset in EDIT.
    Thinks this is going to work , haven't had time to prove it out, due to other work on the Okuma.


    Here's a pic from the manual, maybe it will help some one some day

    Attachment 485370

    As soon as I have it running, I will post the code and make a video about it.
    Still need to come up with a way to get the part out of the subspindle

    Re: LB15W supspindel program question

    So it is like the LB-9W. There is only 1 machine like that in the states. Sorry I had the stop code wrong, but the start code was right. ;-) (I never wrote down the stop code...and the battery is getting weaker!) That's a rare bird that you have there...They were only made like that for less than a year I think. Then it all changed to what we have today.

    You can typically remove the dust cap from the sub chuck and replace it with a spring loaded ejector that bolts into it's place. They came to the USA with that as a standard included item, but I'm guessing yours is lost by now.

    Good luck!
    Experience is what you get just after you needed it.

    Re: LB15W supspindel program question

    As promised, I made a video of how far i got with using the subspindel.

    Last year I could not get it running great, lots of problems with chips in the chuck. So that batch was done the old way ( manualy swaping the part half way the program).
    Now i got a new order of the same parts, need to make 1000 of the same parts, and this time the ordered on time. So we are back at it.

    here's the video's
