Wire EDM Machining Process

time:2009-2-20source: author: TopwedmClick: times

Wire EDM machining (Electrical Discharge Machining) is an electro thermal production process in which a thin single-strand metal wire in conjunction with de-ionized water (used to conduct electricity) allows the wire to cut through metal by the use of heat from electrical sparks.

 

Due to the inherent properties of the process, wire EDM can easily machine complex parts and precision components out of hard conductive materials.

 
How Wire EDM Works
 
Wire EDM machining (also known as "spark EDM") works by creating an electrical discharge between the wire or electrode, & the workpiece. As the spark jumps across the gap, material is removed from both the workpiece & the electrode.
 
                           
 
To stop the sparking process from shorting out, a non conductive fluid or dielectric is also applied. The waste material is removed by the dielectric, and the process continues.
