  1. Re: Programming tailstock advance on program osp 5000

    Go into check data and look for input from foot switch. Should be next to retract input.
  2. Re: Programming tailstock advance on program osp 5000

    Do you have tailstock advance confirmation?

    Normally foot pedal should work unless some interlock is preventing it Do you get any alarm? Does tailstock try to advance or doesn’t even try?

    If...
  3. Re: Wrong home reference VMC MB-46VA +OVERFLOW Position

    The MC Zero Offset is how you accomplish the “grid shift” for the absolute encoders. Once done properly NO data needs to be adjusted for Zero Set, Variable limits, Stroke End limits, etc. It’s change...
  4. Re: Wrong home reference VMC MB-46VA +OVERFLOW Position

    Okuma’s have absolute position encoders so they will know where they are at even if rotated by hand. It is much like the odometer on a car so you are not going to reteach it without using the MC Zero...
  5. Re: need to avoid " chuck clamp confirmation "

    I don’t believe that the air pressure is monitored by pressure switch. Thus it should work in your situation.

    Please try doubtingkitty..,

  6. Re: need to avoid " chuck clamp confirmation "

    Oh I remember possible trick style. Changing to air chuck will ignore switches in favor of timer for clamp unclamp. Default 5 seconds. Of course be careful as before.
  7. Re: Wrong home reference VMC MB-46VA +OVERFLOW Position

    When you get the overflow, the encoder has exceeded its range and you need to add/ sub a value to the MC Zero Offset Parameter until you get rid of the overflow error. At that time, you will have an...
  8. Re: need to avoid " chuck clamp confirmation "

    Simply put, you can only have one ON at a time. The switches reverse meaning when changing from OD to ID chucking.

    Re: Thread cycle command

    G33 can do continuous coordinates so multiple x-z coordinates can be used. This makes possible such things as oil ring grooves using threading style passes.

    Re: OKUMA LATHE LB-3000 SPINDLE REPAIR

    Although the drain comes out of the spindle housing, the area that got clogged was built into the firewall and can be seen without the spindle if you have it. If there is nothing but straight...

    I have see in the past that a drain for the spindle labyrinth seal can get clogged and cause bearing failure. Have you checked by the firewall under the spindle to see if yours has the drain and that...

    Re: OKUMA LB15 SPINDLE DRIVE BREAK TIME

    I agree the belts should be tightened. Try doing an M19 and see if you can move the chuck by hand due to loose belts.

    Ramp up down seems normal. Coasting after stop does not.

    Re: OKUMA LB15 SPINDLE DRIVE BREAK TIME

    Can you give more specific times for braking? For example from 2000rpm to stop, from 3000 rpm to stop?

    I’m guessing on a drive that old that your unit’s regenerative braking may be getting tired...

    Re: AL-4 Lubrication Oil Lack alarm

  15. Re: OKUMA MC-4VA hydraulic unit parameters, pipe connections

    P=pressure. T=tank
    Tank would be return or drain line. Those units were about 750 psi but I’m not sure the flow rate. I’m guessing 10-15 gpm on typical hydraulic system. They didn’t need a lot of...

    Re: Spindle transfer

    There is also an interference parameter so as to keep the spindles from colliding. The parameter is under Spindle 1-2 if I remember correctly. It works rather strange in that the number cannot go...

    CALL OTIME
    M30
    The call will allow you to call OTIME.SUB program.
    Place your code inside the sub and end it with RTS (return from sub)

    You should be able to use the VTIME variable to check the time and then re-check it to compare at the end of the program. It may be easier to use the VDIN[1001] timer for seconds count up from power...
