Mag chucks are certainly common on things like surface grinders. Not quite the same as using discrete magnets to stick something non-ferrous to a ferrous mill table though.

Some sort of cam system that separates the magnets from the conductive surface internally. ----- Original Message ----- From: p...@wpnet.us To: emc-users@lists.sourceforge.net Sent: Wednesday, November 12, 2014 10:45:56 AM Subject: Re: [Emc-users] Question re using magnetics for work holding Put them in a zip loc bag, and if they pickup some ferous chips turn the bag inside out and pull away to remove the chips. Vacuum clamps work with just ~14 PSI of clamping force so I don't see why magnets wouldn't work for light cuts as well. ------Original Mail------ From: "Gene Heskett" <ghesk...@wdtv.com> To: <emc-users@lists.sourceforge.net> Sent: Wed, 12 Nov 2014 10:41:23 -0500 Subject: [Emc-users] Question re using magnetics for work holding Greetings; I was given 4 of the rare earth magnets used in hard drives yesterday, and have visions of using them in lieu of holddown clamps for flat, non- magnetic material clamps on my toy mill. These will exert 150+ lbs of pull when placed over a 1/8 masonite sacrificial, with say a .090" lexan sheet laid on the masonite. Restricting them to non-ferrous material hold downs should keep them fairly clean. They are very strong & Jim got a finger between two of them and sustained a nearly bone crushing injury that took about a month to heal. Has anyone else used these for alu or plastic sheet hold downs? And if they do collect ferrous swarf, an air hose is not going to dislodge the swarf, so how would one go about cleaning them?
