Principle of Spark Machine:
In the dynamic world of Electrical Discharge Machining (EDM), precision is paramount. Here, the tool electrode and the workpiece are ingeniously connected to the opposite poles of a sophisticated pulse power supply. By submerging them in a specially formulated working fluid, or by filling the discharge gap with this fluid, a crucial gap distance is achieved. At this precise moment, the applied pulse voltage triumphs over the fluid's resistance, sparking the initial discharge.
During this fleeting discharge, an immense concentration of heat energy, surpassing 10,000 degrees Celsius, coupled with swift pressure variations, is localized within the micro-channel. This formidable energy causes the metal material to melt, vaporize, and be forcefully expelled into the working fluid. These ejected metal particles then rapidly solidify and are carried away by the fluid, leaving behind tiny pitting marks on the workpiece's surface. The process briefly halts to allow the working fluid to reestablish its insulating properties between the electrodes.
Following this, another pulse voltage instigates a discharge at a new, nearby point between the electrodes, continuously producing spark discharges. Despite each pulse removing an almost negligible metal amount, the high-frequency discharges-numbering in the thousands per second-result in substantial cumulative metal removal, ensuring impressive productivity.
Maintaining a constant discharge gap between the tool electrode and the workpiece is crucial. As the tool electrode advances, it meticulously erodes the workpiece metal, eventually forming a shape that mirrors the tool electrode. By adjusting the tool electrode's geometry and its relative motions, intricate profiles are crafted with precision. Tool electrodes are commonly made from materials with high electrical conductivity and melting points, such as copper, graphite, copper-tungsten alloy, and molybdenum. While the tool electrode undergoes minimal wear compared to the workpiece, this loss is typically insignificant.
The working liquid plays a vital role as the discharge medium, facilitating cooling and chip removal during the machining process. Ideal working liquids are those with low viscosity, high flash points, and stable performance, like kerosene, deionized water, and emulsions. EDM machines function on self-excited discharge principles, where a high voltage initiates the spark discharge between the electrodes. This discharge causes a drastic drop in resistance and voltage. The spark channel must extinguish within 10-7 to 10-3 seconds to maintain the 'cold pole' effect, ensuring the channel energy impacts only a minimal area, thereby achieving localized metal erosion. This meticulous process is known as Electrical Discharge Machining (EDM).
