View Full Version : Need Help! Okuma-Howa tool change problems.

01-02-2009, 08:41 AM
My Okuma-Howa M-4H is in a bit of a jam. I traced a hydraulic leak to the tool change arm, while diagnosing the problem I closed the gripper fingers using the manual controls. The problem is I cannot get them to open up again, nor can I rotate the arm. I restarted the machine to try to clear the problem, now my spindle is no longer oriented to the right place for the tool change and I cannot get it to move (I assume it will not rotate because the tool change arm is out of position). I am also getting alarm 93, but I don't have any manuals so I don't know what that is referring to.

Is there a command I can give in MDI to orient the spindle?
What does alarm 93 mean?
Do you know where I can get some manuals?

Any and all help is appreciated.

On most CNC mills M19 orients the spindle. What control does it have?

It has a Fanuc 11M control.

Thanks for your help.

Which side is this on.... Okuma-Howa or Fanuc?

I have got past the problem, it turns out that I had to press the 'Machine Ready" button and 'Spindle Orient' at the same time.

I still need manuals though if anyone knows where I can get one.

Thanks for your help.
