Working process of wire electrical discharge machining
Wire EDM uses a computer-controlled thin wire to cut conductive materials in deionized water. The spark erosion creates smooth surfaces, cutting down extra finishing work. It delivers precise, high-quality results even for highly complex designs.
Secure the workpiece firmly on the table and fully clean and degrease its surface. Note that only conductive materials work for Wire EDM, as spark erosion delivers reliable micron-level precision.
A thin wire electrode guided precisely cuts workpieces submerged in deionized fluid. Controlled sparks erode material via electrical discharge. This stress-free, non-contact process avoids tool wear and part distortion, ideal for hard, brittle materials needing ultra-high precision.
CNC-controlled wire electrode cuts tight-tolerance contours with no mechanical stress. The circulating dielectric fluid cools and flushes debris to keep stable temperature and fine surface finish. This non-contact process delivers precise complex shapes, ideal for applications demanding full material integrity and accurate dimensions.
Electrical discharge wire cutting Materials
Zorapid Wire EDM machines conductive materials like hardened steel and high-temperature alloys efficiently and precisely. This non-contact process works great on tough heat-resistant metals, delivering accurate, durable parts for strict industry standards.
Stainless steel has excellent corrosion resistance and strength, and can be used to manufacture durable and long-lasting parts, meeting the hygiene and reliability requirements of the medical and food processing industries.
Titanium boasts an exceptional strength-to-weight ratio (crucial for lightweight aerospace structures) and biocompatibility (a core requirement for safe, long-term medical implants), perfectly combining durability and high performance.
Carbon steel and hard tool steel possess excellent toughness and wear resistance, making them highly suitable for high-stress application scenarios — where components need to withstand heavy loads, friction, and repeated use without failure.
Aluminum has the properties of light weight (reducing the weight of vehicles/aircraft), high workability (accelerating production), good corrosion resistance and electrical conductivity, which perfectly meets the core needs of these industries.

FAQ
1： What are the main types of EDM machining?
Wire EDM: Uses a thin wire electrode to cut intricate, tight-tolerance shapes in conductive materials, used in aerospace, medical, and electronics.
Sinker EDM (Ram EDM): Uses a custom-shaped electrode to create detailed cavities, molds, and dies, ideal for tool and die making.
Hole-Drilling EDM: Specializes in drilling small, precise holes in hard materials, perfect for turbine blades and wire EDM pre-processing.
2：Can Wire EDM machine hard materials？
Wire EDM uses electrical discharges from a thin wire electrode to erode material, making it ideal for cutting tough conductive materials like hardened tool steels, titanium, tungsten carbide, and superalloys. Unlike traditional machining, it requires no mechanical force, eliminating tool wear and material distortion, while achieving intricate shapes and tight tolerances for aerospace, medical, and tool & die applications.
3：Just how precise is Wire EDM?
Wire EDM offers exceptional precision, with tolerances as tight as ±0.0001 inches (2.5 microns). Thanks to advanced CNC controls and a thin wire electrode, we can machine intricate, complex shapes with consistent accuracy. Not only does this meet the strict standards of aerospace and medical industries, but it also delivers smooth surface finishes that often eliminate the need for extra finishing work.
4：What shapes can Wire EDM create?
Wire EDM produces a wide range of intricate, high-precision shapes, including sharp internal corners, complex contours, and detailed patterns that are difficult for conventional machining. It handles both 2D and 3D geometries, cutting thin walls, small holes, and narrow slots with high accuracy. This makes it ideal for aerospace components, medical devices, and detailed molds & dies.
5：Can Wire EDM cut very thick materials?
Wire EDM can cut materials up to 12 inches (300 mm) thick with precision and efficiency. The process uses a thin wire electrode to erode material, allowing distortion-free cuts through dense, hard metals. This makes it ideal for large molds, heavy-duty components, and aerospace parts, ensuring consistent accuracy even in thick stock.
