Continuous miners. Though there are many variations in design, continuous miners mostly consist of five main elements: A central body to carry all other components mounted on some type of drive mechanism to provide mobility (most commonly tracks). A "cutting head" usually rotating drum(s) and/or chains with cutting picks attached

Sep 01, 2000· HighPerformance Graphite Electrode Machining. Today, it is popular to talk of eliminating electrodes for hard die milling. While it is true that the machining process for hardened steel has advanced by leaps and bounds, the production of electrodes (graphite or copper) is, and will remain, a critical process for the production of molds.
