Wire Erosion / EDM
H V Wooding provides precision Wire Erosion (Wire EDM) services with over 40 years of expertise, achieving tolerances as fine as ±5 microns — around 15 times thinner than a human hair.
This non-contact CNC process uses a fine wire and controlled electrical discharges to cut conductive materials with no mechanical stress, no burrs and distortion-free results. Ideally suited to intricate shapes, fine holes and thin-walled components, it delivers exceptional surface finishes without the need for further machining.
Our fast turnaround, reliable quality and proven results across aerospace, medical, motorsport, electric vehicle and research sectors make us one of the UK’s most trusted EDM partners.
Capabilities
Our facilities operate around the clock and feature advanced Charmilles wire erosion machines with automatic wire feeding, submerged cutting for thermal stability, and capacity for components up to Ø500mm by 500mm deep. Multi-loading beds support both batch and volume production, while the latest generator technology ensures excellent surface quality. We provide rapid prototyping as well as high-volume manufacturing, supported by full inspection capability, including CMM and Quick Scope metrology.
Why choose H V Wooding?
Choosing H V Wooding means partnering with one of the UK’s most established EDM specialists. We combine advanced Charmilles technology with certified quality systems (ISO 9001, ISO 14001 and ISO 45001) supported by FMEA and SPC. Customers benefit from rapid prototyping, flexible lead times, reverse engineering capability, and full inspection, ensuring accuracy and repeatability for every project.
Case Study
Our expertise is trusted worldwide — demonstrated by our work with CERN, where we manufactured high-grade steel yokes for the Large Hadron Collider. These critical components were cut to sub-5 micron tolerances, meeting some of the most demanding specifications in the world.
