Wire EDM Hyderabad
Tek4s provides precision Wire EDM services for manufacturing intricate metal components with tight tolerances and superior surface finishes. Using advanced CNC-controlled EDM machines, we can cut complex profiles in hardened steels, alloys, and conductive materials with micron-level accuracy. This non-contact process eliminates mechanical stresses, making it ideal for tooling, molds, dies, and high-precision engineering parts. Tek4s ensures exceptional repeatability, burr-free edges, and dimensional stability — even in the most demanding industrial applications.
Wire EDM Services at Tek4s
Wire EDM (Electrical Discharge Machining) is one of the most precise and reliable methods for cutting electrically conductive materials, especially where traditional machining cannot meet required tolerances or geometrical complexity. At Tek4s, we have integrated advanced CNC-controlled Wire EDM technology to deliver micron-level accuracy, burr-free surfaces, and superior edge quality across a wide range of engineering applications.
1. Process Overview
Wire EDM uses a thin brass or copper wire as an electrode, which cuts through the workpiece using a controlled electrical discharge (spark erosion). The material is removed by rapid, localized melting and vaporization, without any mechanical contact between tool and workpiece. This allows for cutting even the hardest materials such as tool steels, tungsten carbide, titanium, Inconel, and hardened alloys, with perfect precision.
The process is conducted in a dielectric fluid (usually deionized water), which cools the material and flushes away debris, maintaining dimensional stability and surface integrity.
2. Precision and Capabilities
Tek4s’ CNC Wire EDM machines operate with cutting accuracies up to ±2 microns and surface finishes as fine as Ra 0.2 µm. This makes our service suitable for producing precision tooling, punches, molds, and complex metal parts where tight tolerances and sharp internal corners are critical.
Our machines support 4-axis simultaneous motion, allowing the creation of tapered cuts, intricate geometries, and multi-level profiles. Whether it’s a one-off prototype or high-volume production, Tek4s ensures repeatable precision on every part.
3. Applications
Wire EDM is extensively used in industries that demand exceptional accuracy and part integrity, such as:
Automotive and Aerospace: Precision dies, turbine blades, valve components, and injection mold inserts.
Medical: Surgical instruments and implant tooling.
Tool & Die Manufacturing: Punches, dies, and forming tools for stamping and injection molding.
Electronics: Micro-components, connectors, and contact elements.
4. Engineering Advantage at Tek4s
Our experienced engineers perform CAD/CAM programming and process simulation before cutting begins to optimize electrode paths, reduce cycle time, and ensure maximum material utilization. We also analyze part geometry for corner radii, spark gap compensation, and kerf width to achieve precise dimensional control.
Tek4s’ non-contact EDM process eliminates mechanical stress, deformation, and chatter marks associated with traditional machining. This makes it perfect for delicate and high-hardness materials.
5. Quality Assurance and Finishing
Every EDM-cut component is inspected using CMMs (Coordinate Measuring Machines) and optical comparators to verify dimensional accuracy and surface quality. When required, we offer post-processing services such as polishing, surface coating, and sub-assembly integration.
By combining technology, expertise, and process control, Tek4s delivers Wire EDM services that meet the highest international standards.
