Lock Spindle

[Paul McGarr]

I tried a quick search and didn't find anything so I figured I ask this...

 

We just purchased an air spindle for our machine. The spindle mounts in the tool holder, but can not rotate. I want to ensure that the spindle stays locked and refuses to turn on. Is there a way to do that?

 

I am aware of the fact that I can use M19 to orient the spindle, and I plan to do that but I am trying to find a way to force the spindle to stay locked and off. I also want to stop the machine from making a tool change even if the program tries to do so.

 

Is this possible. I am simply trying to eliminate the possibility of damaging this $5,000 spindle.

 

I have a Mitsubishi Meldas 520AM control. I am hoping I am missing some standard functionality.

 

Any advice would be appreciated.

 

Thanks,

I use M3 S0 (zero) and M19. About you tool change...dont put it in the code with the air spindle.

I program all my air spindle paths seperately so that wont happen

I just realized that we have a switch for T, S, and M Function Lock. That will lock out T, S, and M codes all together. This is what I was after. The only thing that can go wrong is that the spindle will unlock, but it can't turn on, or make a tool change. I wouldn't be able to program coolant, but I am using manual air, so that's not a problem.

 

I guess I answered my own question. I feel better knowing that I can't accidently do a tool change, etc.
