At Lewei, we harness the power of Wire Electrical Discharge Machining (EDM) to deliver precision-engineered components to our clients. Wire EDM is a highly specialized process that employs controlled electrical sparks to create intricate shapes and details in metals. This is achieved by generating a regulated electrical discharge between two electrodes submerged in dielectric fluid, which melts and vaporizes the metal with exact precision.
The true advantage of wire EDM lies in its capability to machine complex contours and fine details in materials that are difficult to process with traditional CNC machining. This includes heat-treated steels, superalloys, and other specialized metals. Wire EDM enables parts with extremely tight tolerances and fine features, such as narrow slots and small holes, with unmatched accuracy. Our services suit applications demanding high precision, including aerospace components, automotive parts, and detailed molds and dies. Lewei combines advanced wire EDM equipment with skilled technicians to ensure every cut meets exacting standards, making us a leader in wire EDM machining.
Machining Works
In wire EDM machining (Wire Electrical Discharge), a thin wire, precisely guided by computer systems, passes through a workpiece submerged in deionized water. Acting as both guide and electrode, the wire uses controlled electrical discharges to cut conductive materials with high accuracy, producing parts with finely finished surfaces that rarely need additional processing. Lewei’s state-of-the-art facilities ensure that even the most intricate designs are machined with precision, demonstrating our commitment to quality and customer satisfaction.
The first step is to firmly secure the workpiece onto the EDM machine’s worktable, making sure it stays completely stationary. The surface is then carefully cleaned and degreased to eliminate any contaminants. It is essential that the workpiece material is conductive, since wire EDM relies on a conductive medium to operate effectively.
Next, a fine metal wire is threaded through the machine’s guides while both the wire and workpiece are submerged in a dielectric fluid, typically deionized water. An electrical voltage is applied, causing the fluid to ionize and permitting an electrical discharge (spark) to occur, gradually eroding the surface of the workpiece.
The final step involves accurately controlling the wire’s motion using a computer numerical control (CNC) system. The CNC directs the wire along a defined path, allowing it to cut intricate shapes and profiles into the workpiece. The dielectric fluid circulates continuously to clear debris and regulate temperature during cutting. After completion, the workpiece is extracted, producing a high-quality, precisely finished part.
