 1).Basic working fundamentals of  the EDM

EDM is also known as electric spark machining. It’s a direct utilization of electrical energy and heat processing technology. It is based on during the spark discharge between the tool and the workpiece for removing excess metal in order to achieve the dimension, shape and surface quality of the predetermined processing requirements, as shown in Figure 1.

2). The composition of  the EDM  

The EDM is made up of the main machine, working circulating fluid filtration system and power box. As shown in Figure 2.

1. The main machine is mainly composed of bed, carriage, worktable, column, upper drag plate, spindle head, clamp system, lubrication system and transmission machine.

 2.Working liquid circulation filtration system includes working liquid tank, liquid pumps, filters,pipeline, oil tank and some others. They make the forced working fluid circulation. As shown in Figure 3.
