Machining copper - practicalmachinist.com

Mar 01, 2010· Like Mickey D says, copper can be a royal pain to deal with. We used to run a lot of 1 1/4" round bar in the CNC lathe at work. Problem with copper is that it is SOOO malleable. It flows nearly as much as it cuts. You could make a threading pass and sometimes it would actually INCREASE the outer diameter, as the metal flowed around the tool.
