A Milling machine is a machine tool used for the shaping of metal & other solid materials existing in two basic forms: horizontal & vertical, which terms refer to the orientation of the cutting tool spindle.
Turning is the process wherby a single point cutting tool is parallel to the surface. It can be done manually, in the traditional form of a lathe, which frequently requires continuous supervision by the operator, or by using a computer controlled and automated lathe which does not.
In wire electrical discharge machining (WEDM), or wire-cut EDM, a thin single-strand metal wire, usually brass, is fed through the workpiece, typically occuring submerged in a tank of ELECTRIC fluid. This process is used to cut plates as thick as 300mm and to make punches, tools and dies from hard metals that are too difficult to machine with other methods. The wire, which is constantly fed from a spool, is held between upper and lower diagonal guides.
