Electric Discharge Machining (EDM), also known as Spark Erosion Machining, refers to the machining of workpieces through the galvanic action of a pulsed discharge between a tool electrode and a workpiece electrode in a certain medium. method.
Electro-discharge Machining is a kind of special processing technology. Its machine types are divided into two types: ordinary spark machines and mirror spark machines. EDM has been widely used in mold manufacturing and precision machining industries sales@zxmade.com.

EDM process can be used to machining hard-to-process superhard materials and complex-shaped workpieces that are difficult to machining with conventional cutting methods.
They are often used to process conductive materials, such as aluminum alloys, steels, stainless steels, titanium alloys, zinc alloys, magnesium alloys, copper and even Difficult-to-machine materials such as tungsten steel are used to machining complex cavities or contours.
Wire Electrical Discharge Machining; Also call WEDM, its working principle is the use of continuous moving thin wire (called electrode wire) as the electrode, the workpiece pulsed spark discharge metal removal, cutting and forming.
Wire cutting technology is a kind of special processing, which is different from the traditional mechanical processing technology that requires mechanical and mechanical energy to remove, and mainly uses electrical energy to realize the processing of materials. Therefore, the WEDM technology is not limited by the material properties and can process any hardness, strength, and brittleness. It is a very important process in machining sales@zxmade.com.
