We have a Hyudai 180 with the Oi-T controller. I would like to true up the boss that the chuck originally sat on. Can someone tell me how to enter a speed & get the spindle end of the lathe turning so I can handwheel slowly to true this boss up. This boss is .007 out or round while the piece it bolts to is dead on. Thank you.

Stevo,

I might be wrong, but I'm guessing you meant G97 (RPM), not G96 (SFM). The spindle might take off at some ungodly high RPM unless he has a tool offset active...

[stevo1]

Dave….yes you are correct my apologizes. I usually use G96 however I have a G92 for max speed programmed right before it. And as always a lot of these safe settings I have long programmed them into macros and tool calls etc etc that way things like this are less likely to happen. Bad habits….anyway thank you for the correction.

Thank you for the replys. I will give that a try today if I can get to it.

I must be missing something. I keyed in G97S100M3 & when I press cycle start it clears out the code & nothing happens. I do have it in MDI mode.

[dcoupar]

Did you type in G97S100M3 and press EOB and INSERT? Then CYCLE START.

[tedh]

no I didn't. I just typed the code & pressed the cycle start button. I will try that. Thank you.

[tedh]

I tried that & it still didn't work. Our machine has been modified slightly & something in the controls may have been used for another function because it tells me the chuck is not closed & we don't have a chuck on the machine anymore.

[dcoupar]

There may be a proximity switch or two on the actuator that tells the control the chuck is open or closed. Check these. Also, there may be a OD/ID chucking switch. You might try changing this and actuating the foot pedal to see if the chuck clamp lamp illuminates.

On my kia with oi-t ...G97s1000....end of block .....cycle start ...then enter m03 end of block...cycle start....spindle should come on.....for some reason m code has to be on seprate line from g-code...on my new machine....give it a try...
