1)Basic working fundamentals of 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 Machine
The EDM is made up of the main machine, working circulating fluid filtration system and power box. As shown in Figure 2.
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.
3. In the power box, the function of pulse power, which is exclusive for EDM processing, is to change industrial frequency exchanging current into one-way pulse current with certain frequency in order to supply the power to spark discharges for eroding metal. The pulse power has a great influence on technological and economic indicators, such as EDM processing productivity, surface quality, processing rate, processing stability and tool electrode loss.
