View Full Version : UNWANTED MAGNETISM
02-22-2005, 08:39 AM
PLEASE HELP! I recently inherited a Jet bench mill/drill. Once I got everything set up, I eagerly started machining a piece of cast iron. Most of the chips did not fly everywhere as they usually do. Here's the problem: the vise and table are magnetised! Does anyone know of a way to demagnetise ferrous materials?
Check the industrial tool catalogs (MSC www.mscdirect.com (http://www.mscdirect.com) and others) for demagnetizers. Radio Shack might even have something, although it may not be big enough to be practical.
Basically, what you need is an alternating-current electromagnet. Bring it up close to the magnetized piece, then slowly draw it away.

Thanks, SGW! MSC has several affordable models. I'll give one a try soon.
