General tips on milling/turning copper

Apr 27, 2012  HSS tool bits actually work very well when machining copper. Trick is to have a large swooping radius on the top face of the tool ( like this --> ) but rotated 90°) and a steep cutting angle of 20° or higher. After grinding, hone the cutting edges sharp with an India stone. Works great, but needs lubricant as suggested above.

What Is Copper Smelting? (with pictures)

Kirsten C. Tynan Copper wire. Copper smelting is the process of separating copper metal from the rock in which it is naturally embedded by melting it. This is accomplished through a series of several processing steps. The term copper smelting may refer to this melting step in particular or it may refer somewhat less formally to the entire process overall.
