EDM machines for extremely hard material
PCD (polycrystalline diamond) can only hardly be machined. Manufacturing of hard metal tools often shows problems, too. These materials are extremely hard. The tools are used with high speed of 40 000 rpm or more and must be made perfectly rotationally symmetrical.
These problems can be solved precisely and with process safety by manufacturing on wire EDM which offer the right cutting technology and are equipped with a precise rotary indexing table.
