Copper Ore Milling Machine

Feb 28 2010nbsp018332Like Mickey D says copper can be a royal pain to deal with We used to run a lot of 1 14quot 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
