A lathe cuts in a circular motion. You could cut a groove in a piece of steel on the lathe as long as you wanted it to run around the circumference of the steel piece. You can also cut threads in a round piece of steel with a lathe.
A milling machine can cut grooves, slots, in metal or steel and in any direction. It doesn't just have to follow the outer edge in the direction of rotation like a lathe has to do. ----- Original Message ----- From: Bill Stephan To: blindhandyman@yahoogroups.com Sent: Thursday, June 18, 2009 10:30 AM Subject: RE: [BlindHandyMan] New router: was new toy Dan and all: Is it possible to use one of these, or a larger router to cut grooves in metal, or is that something that requires a lathe?

Basically, it is a small hand-held router. Probably great for edge trimming and such. -- Blue skies. Dan Rossi Carnegie Mellon University.
