Haas Control and Vacuum Chuck

[big_mak]

I'm looking to use a vacuum chuck for some of the prod. parts we are making.

What I want to know is can I use a Vacuum gage to trigger an alarm condition, when the Vacuum is lost to a certain point?

I know some one who's rigged this type of system up on some fancy pants japanese machines.

Possible to do with Haas????

I also want to know if I can adjust the airblast time during the tool change. I'd like to be just a bit longer to make sure the taper is getting flushed just right!!

The easiest way would be to wire it into the door safety circuit. That way the machine would respond just like a door was opened. You'll want to run a switch in parallel with your sensor, that way you can switch it to a bypass mode when you aren't using the vacuum system.

The easy way to do it is with the door switch circuit and set the Door Stop Spindle Parameter to 1 so that both the Feed and Spindle stop if you lose vacuum. Then remember you must not run with the Door Hold Override on.
