Hi guyz, another quicky...

I'm want to run my milling cutters dry, and use air to clear the chips.
There is no option in IGF (only ext/thru spindle, coolant on/off).

I've tried every M code in the book for additional air blast, plus the ones listed in the on-screen help, yet none of them work!

Is there a parameter I need to be looking for?

I asked Okuma and they told me M50/51, which is no good(thru spindle, creates alarm), and M868/869 which is used during toolchange and tries to inch the spindle(another alarm). I had tried both of these before ringing Okuma, too.

Any help is greatly appreciated.

M50/M51 is thru spindle air blow, all tool types. I know on Okuma mills you can blow thru spindel while cutting, but i do not think you can on Multus. I think i had a customer with the same issue. What did the distrubutor say?

[Superman]

Mills use
M50= thru tool coolant
M51= thru tool coolant -high pressure

and on our horizontal (MX40-HA)
M12 = external air ON
M339 = air blow thru spindle
M9 = all OFF
conditions for air blow , spindle must be OFF, air ON then spindle ON
air holes must not allow pressure build-up ( blows the coupling seals at the back of spindle )

The codes may match up for you

What did the distrubutor say?

I havn't heard back since their last two suggestions didn't work...

[DIFF OVER]

figures. please make sure on the multus you do not have / get a chip issue on the spindle face. this is a know okuma issue. okuma does have an bulletin out on this issue. the distributor AE should have set you up with 3 m- code macros for this issue.

So did you ask again?

Thru spindle air is an option on a Multus lathe. Did you purchase the option? If not then I guess that is why it does not work and there is no M code.
M868/869 is for cleaning the thru coolant out of the spindle, This M code function includes spindle inching which is set in the parameters, This cleaning function cannot be used for more than 1 minute.

There may be a bulletin issued in the USA but not from Okuma Japan. Just out of interest what are the "New" M codes?

Thanks for the reply, Yes that will work but there is an easier way, Try changing the Toolchange code to 341 in IGF and use M341 in place of M321 and clean all tools

save this as a lib file

So did you ask again?

Thru spindle air is an option on a Multus lathe. Did you purchase the option? If not then I guess that is why it does not work and there is no M code.
M868/869 is for cleaning the thru coolant out of the spindle, This M code function includes spindle inching which is set in the parameters, This cleaning function cannot be used for more than 1 minute.

Yes, I did ask again.
I told them over the phone that I had already tried both M51 and M869. I asked a 2nd rep in person after explaining what I had tried, and got the same answer.
I was told the one minute thing, but neither mentioned it was an option, or that the inching could set by parameter. So what does that mean anyway? Not more than one minute- can I have it on for 59s, turn it off then back on again for another 59s??

I'm not surprised that it is an option, considering that milling dry is a normal thing to do in a lot of cases.
