EDM Machining
EDM Machining is a non-traditional machining method that uses electric spark discharge to cut materials. The working principle is to generate high temperature through the pulse discharge between the electrode wire (usually copper or brass) and the workpiece, so that the workpiece material is partially melted or vaporized, so as to achieve cutting.
Wire EDM Machining
Wire EDM machiningis a precision machining technology using the principle of electric erosion. Through the high-frequency pulse discharge between the electrode wire and the conductive workpiece, the workpiece material is partially melted or vaporized, and the geometric shape of precision parts, special-shaped holes, narrow cracks and other traditional tools are difficult to achieve is machined. It is very suitable for precision, complex, high-precision and strict tolerance parts.
Low-Speed Wire EDM
Low-Speed Wire EDM is an advanced form of electrical discharge wire cutting. By using a unidirectional low-speed moving wire (such as brass wire, galvanized copper wire) as an electrode, the corrosion effect of electric spark discharge is used to cut conductive materials, achieving high-quality surface requirements and high-precision parts with strict tolerances.
The Core Advantages Of Edm Processing Services
EDM machining delivers micron-level accuracy (±0.005mm) on hardened materials, enabling stress-free fabrication of intricate geometries with mirror-like finishes – the ultimate solution for aerospace and medical critical components.
- Processing materials and complex shape workpieces that cannot be cut by ordinary cutting processing methods.
- No cutting force during processing.
- Does not produce burrs and knife marks and grooves and other defects.
- The tool electrode material need not be harder than the workpiece material.
- Direct use of electrical energy processing, easy to achieve automation.
- After processing, the surface produces a metamorphic layer, which must be further removed in some applications.
- Wire EDM machining reduces errors caused by material deformation and loss through multiple cutting technology, improving processing accuracy and surface finish.
- The speed of the wire cutting machine can be switched between high and low speed. To reduce vibration and improve machining quality.
- Processing a variety of metal materials including tungsten carbide, stainless steel, titanium alloy, etc., and is not limited by material hardness and brittleness.
- The double shell is completely closed and the fast clamping mechanism is adopted to ensure the stability and reliability of the parts.
- Equipped with integrated control system and programming system, it is easy to operate and can achieve high quality and high speed processing.
- Nano-level precision ±0.002mm ultra-high precision, to meet the aerospace fuel nozzle/medical implant microholes.
- Mirror-grade surface quality, Ra 0.1μm super finish, without polishing process, directly used for optical mold/high light auto parts.
- Mirror Surface Finish:, Ra 0.1μm eliminates post-polishing for optical molds & automotive gloss parts.
- Cutting force free machining of complex contour parts, and stress-free cutting of ultra-thin parts and deep and narrow grooves.
- Specializing in hardened steel (HRC 65), cemented carbide, etc., is an expert in hard materials.

EDM Service FAQ
Choosing the Right Wire EDM Partner: 3 Critical Questions
Can you handle micro wire EDM tolerance below 0.005mm?
Do you have experience in my industry (e.g., automotive, aerospace)?
What's your average turnaround time for 100-piece batches?
What is Wire EDM ?
Electrical discharge cutting (Wire EDM) is a non-contact discharge machining technology that etches conductive materials with controlled EDM to achieve micron precision requirements for parts.
What materials can Wire EDM process?
Compatible with a variety of materials processing, including tool steel (SKD11, H13), stainless steel (316/304), copper, aluminum alloy and hardened steel (HRC60+), especially suitable for high hardness difficult to process materials.
What is the lead time for a Wire EDM job?
The lead time of Wire EDM processing mainly depends on: part complexity, material type, order quantity, and post-processing needs.
