  • Milling (machining) - Wikipedia

    Milling is the process of machining using rotary cutters to remove material by advancing a cutter into a workpiece. This may be done varying direction on one or several axes, cutter head speed, and pressure. Milling covers a wide variety of different operations and machines, on scales from small individual parts to large, heavy-duty gang milling operations.

  • Oxidation of chalcopyrite by extended milling - ScienceDirect

    Dec 01, 2005 · After 20 h milling, the peaks for chalcopyrite were absent. The only phases which could be confirmed as present were Fe 2 O 3, CuSO 4 ·5H 2 O and S. Further milling to 50 h resulted in crystallite refinement of these phases with the concomitant weakening and broadening of the peaks making positive identification difficult.
