Turning coolant on and off?

[Jeff2005]

Didn't really know what to call the topic since I do understand how to turn spindle coolant on and off. What I don't understand is how do I cut the spindle coolant off in between operations and force the spindle to turn on.

I use the same tool for one operation that uses thru the spindle coolant to get rid of my chips then the next operation I use the same tool that doesn't need to use thru the spindle coolant. It is not turning the spindle back on. Is this a post issue?

 

please help

 

thanks in advance.

If I understand correctly, canned text can help with this problem.

Why is it turning the spindle off in the first place? What code is it using?

[Jeff2005]

The coolant won't cut off unless the spindle is off. It is not putting a code to turn the spindle back on.

Jeff,

I think this is something you can fix on your toolpath parameters page, isn't it?

 

Can't you just set the coolant ON for one toolpath and coolant OFF for the next, or have you done that already?

 

Like teh Stork said...why is the spindle even turning off in the first place if there's no tool change?

 

Can you post a snippet of your code here so we can better understand what's happening?

 

It also usually helps if you can tell us what post / control / machine combo you are using.

So when you call an op stop it doesn't turn the spindle back on?

 

Sounds like a post issue to me..

 

But you could just do the other op with coolant off like suggested.

Haas machine with a Haas post, Fanuc control

 

I have already done the on and off coolant.

haas machines turn the spindle off to turn the coolant off, so my thinking is, it should be the Haas machine. Would you agree?

ya HAAS uses coolant to cool the spindle....you need to override the control maybe

 

Never ran a HAAS with a Fanuc control...

 

We always just leave the coolant puking in a corner to keep the spindle cool on long progys..

I was doing a hole then I went to an OD which normally I don't use coolant at all with this tool but I used it to remove chips out of the hole.

 

I may just have to use the flood coolant instead of the thru the spindle, if this comes up again I know that will solve the problem.

 

It seems to me this would be an easy fix.

[Jeff2005]

Have I stumped everyone with this question?

Was I not clear enough? Do I need a better explanation?

 

thanks,

Jeff,

I'm guessing you need an M8 for coolant, an M7

for thru coolant and an M3 after M7.

Your post will need some editing for that.

[Jeff2005]

M88 is thru spindle on

M89 is off

M08 is flood

M09 is off

 

Would there be a code to make sure that when the machine turns thru the spindle coolant off that it forces the spindle back on?

It sounds more like a machine issue, than a post issue.

jeff,

 

if your'e convinced it's a machine issue, can you check the haas operators or programming manual. if your'e right, you should be able to nail it down and head in the right direction.
