Vacuum chuck questions

[Bob W.]

I have a Haas Mini Mill and I am contemplating making a vacuum chuck for it and this raises a few questions...

 

1. Can I rig a pressure sensor to the mill so that if the vacuum is lost the mill will stop (same as when the main air supply pressure drops below 80 psi) ? If so, is this difficult?

 

2. Any drawbacks or risks associated with using a vacuum chuck?

 

Thanks,

Bob

I'm in the process of making a vacuum chuck to use on my Mini mill and Sharp. You want to make a master with insertable plates for your different parts. Use an air tank to act as a resevour. I have a little compressed air vacuum pump that works very well but then I don't do really large parts. But it draws down to 27lbs.
