What is Wire EDM？

Wire EDM, a Wire Cutting Machine, is a process developed on the basis of Electrical Discharge Machining (EDM). Its basic principle is to use a moving thin metal wire as the electrode to cut the workpiece in shape through pulsed spark discharge. It is commonly used to cut harder metals that are not conducive to standard machining processes, such as sheet material, tools or punches, etc.

Since the slow-speed EDM cutting adopts the method of continuous wire feeding by the wire electrode, that is, the processing of the wire electrode is completed during the movement process, so even if the wire electrode is worn out, it can be continuously supplemented, so the wire EDM accuracy of the parts can be improved.

How Wire EDM
Machining Works ______

Wire EDM machining, also known as Wire Electrical Discharge Machining, involves a controlled thin wire guided by computer systems cutting through a workpiece submerged in deionized water. The wire serves as both a guide and electrode, using electrical discharges to accurately cut conductive materials and produce parts with finely finished surfaces that often do not need additional processing. U-Need's advanced facilities guarantee precise execution of even the most intricate designs, demonstrating our dedication to quality and customer satisfaction.

Step 1 Prepare the Workpiece

To begin, firmly secure the piece onto the worktable of the EDM machine to prevent any movement. Next, clean and degrease the surface completely to eliminate any impurities. It is essential that the material of the workpiece is able to conduct electricity, as wire EDM relies on a conductive substance to operate effectively.
Step 2 Establish the Electrical Discharge

Then, a slender metal wire is threaded through the machine's channels and both the wire and the piece being worked on are immersed in a dielectric fluid, typically deionized water. An electric charge is activated, leading to the breakdown of the fluid and enabling an electrical discharge (spark) to take place, gradually wearing away the surface of the workpiece.
Step 3 Control the Wire Movement

The last stage involves accurately managing the wire's motion through a computer numerical control (CNC) system. The CNC directs the wire along a set route, allowing it to carve intricate shapes and designs into the material. A dielectric fluid is constantly circulated to clear away any waste and regulate the temperature while cutting. After the cutting is finished, the material is taken out, leaving behind a finely crafted, high-quality part.
