In Wire EDM, an electrical discharge is created between the wire and the workpiece. During the trigger process, a trigger is sent out from the fastest range between a single strand of the material, usually brass, and the work surface where it jumps the void (referred to as the stimulate space) whereupon the material is melted far from the workpiece. For the purpose of preventing the sparking process from shorting out, a non-conductive fluid is used to wash or immerse the entire EDM process. This is accomplished by the continuous flow of the dielectric liquid, which is cooled down and is filtered throughout the entire process. Due to the fact that wire EDM is primarily utilized to cut forms with assemblies and inserts, it is typically necessary to predrill a hole before the wire can be fed in order to complete the machining process. Only when the cut needs to experience the entire work surface can Wire EDM be used.
WIRE EDM’S BENEFITS
Cuts with precision; wire EDM can achieve a precision of +/-.0003″.
An interior edge cut with nearly square sides.
Capable of reducing lengthy taper lengths that would otherwise be impossible.
Shorter lead times are achieved by extra-precise production and prototyping.
Accurately and repeatedly equipment delicate and detailed parts without deflection.
Burrs are not produced by wire EDM.
Does not require tooling.
Devices pieces up to 12 inches in diameter.
Because the machining takes place after heat therapy, the distortion caused by the heat treatment is not a factor in the dimensional precision.
