EDM Spark Erosion

EDM Spark Erosion

Microtec EDM Limited specialise in all aspects EDM spark erosion and wire erosion technology. Establishing in 2001, we quickly gained a solid reputation for producing high-quality precision parts at competitive prices.

Gaining ISO 9001 compliance in February 2005, the company has continued to improve and update its production capabilities. Incorporating the latest GF Machining solutions EDM technology as well as Nikon CMM video measuring equipment to provide a comprehensive quality inspection service.

Microtec’s highly qualified and experienced staff are able to provide a complete production service. From CAD design assistance and prototyping to mass production of components incorporating full product traceability throughout the process.

“Our latest Micro EDM machinery is capable of utilising 20-micron wire and can consistently maintain tolerances of less than 3 microns!”


Spark erosion is a process in which the creation of an electric spark within 8-12 thousand degrees Celsius, between an electrode (cutting tool) and the workpiece effectively 'vaporising' the material to create the required design. Microtec's Charmilles Roboform 350 machine combines high-speed finishing, micro and automated tool changer capability thus speeding up the production process. Lower electrode wear also keeps down the cost of the product.


Wire erosion is an extremely accurate method of producing parts from any electrically conductive material with high-quality results. Microtec's fleet of EDM Machinery represents the best in high-end, micro precision technology currently on offer from Charmilles. These suits the production of intricate, complex parts, down to 20 microns with tolerances of less than 3 microns. The added advantage of the latest CNC technology means these machines can run 24 hours a day, 7 days a week, allowing for very competitive pricing and quick turn around times. This method of precision engineering obviously suits both small and high volume batch work. However, it is also suitable for one-off and prototype enquiries.
