Copper Tungsten Alloy become easier to machine as the copper content increases. The more tungsten content present the more care must be taken when machining. Carbide tools are suggested for most cases and a coolant is optional. Cutting and Sawing Copper Tungsten. ... Grinding – Use aluminum oxide or silicon carbide wheels of medium hardness.

Using abrasive cutoff wheels on copper and brass. At some point I read that it's extremely dangerous to cut nonferrous metal with abrasives, because of something to do with the pores in the material filling up and making the wheel much more likely to explode. This was just one source though, and I haven't been able to find anything else about it.

even with larger samples of pure copper, plane grinding with 500# SiC Foil/Paper is sufficient. Large cast parts of copper alloys can be ground with 220# or 320#. It is also important that the force for grinding is low to avoid deep deformation. As indicated in the table with the prepara-

A process for abrasively grinding copper comprising (1) cooling the entire copper workpiece to a cryogenic temperature and (2) abrasively grinding the copper workpiece while it is at said cryogenic temperature. The workpiece is preferably immersed in liquid N2 during the abrasive grinding thereby preventing adhesive wear from occurring at relatively high metal removal rates.

Copper grinding process. This is the process of separating precious minerals from waste rock. At Britannia the copper ore contained just over 1% copper (though in the early years it was around 8%). The remaining 99% was mostly waste rock, called 'tailings'. In the rock, chemical and physical bonds hold the valuable minerals to the waste rock.
