The process of removing material from a workpiece by advancing rotary cutters cutter into it is called milling. The process is carried out by adjusting pressure, speed of cutter head, and direction of feed. A milling machine is a piece of equipment that removes a layer of material from the surface by using a multipoint cutting tool.

Gold processing Mining, Concentrating, Refining: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by ...

CNC milling process. A CNC milling machine uses a rotating cutter in a cylindrical shape. The plasma cutter moves in multiple Axes. The plasma cutter creates slots and holes in the material that later turns into a part. Standard machines operate on three to five axes. That makes precise cuts and more detail than on 2 Axis.
