General tips on milling/turning copper - Practical Machinist

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.

Lapping and Polishing Basics - South Bay Tech

Grinding can be defined as the rapid removal of material from a sample either to reduce it to a suitable size or to remove large irregularities from the surface. The grinding wheel or plate typically rotates at a high speed (around 200-1000rpm) and a coarse, bonded abrasive (> 40 µm) is used. Grinding is quick and relatively easy process but can

material science - Why does grinding steel create sparks ...

While grinding metal, sparks are produced because of Friction. The rotating grinder cuts through the metal molecules, rubbing against them and producing heat. Some particles get loose in this process and burn because of this heat. From Wikipedia, "Steel is an alloy of iron, with carbon being the primary alloying element, up to 2.1% by weight ...

The remaining mixture is a molten copper sulfide referred to as matte. The next step in the refining process is to oxidize liquid matte in order to remove iron to burn off sulfide content as sulfur dioxide. The result is 97-99%, blister copper. The term blister copper comes from the bubbles produced by sulfur dioxide on the surface of the copper.
