About Rank Erodiertechnik
Rank Erodiertechnik is a sole proprietorship founded in 2012 by Christian Rank in Bretzfeld (Unterheimbach), specializing in contract manufacturing by wire EDM. The service portfolio includes wire EDM in water and oil dielectric, micro wire EDM with wire diameters down to 0.03 mm, start-hole drilling, contract programming for Sodick controls and ESPRIT CAD/CAM programming. In addition, the company offers fixture building for wire EDM machines, training for Sodick machines and ESPRIT, and application technology consulting. All electrically conductive materials are machined, including hardened steel (1.2379), carbide, PCD, copper and graphite. With tolerances below 2 μm and surface finishes down to Ra 0.04 μm, Rank Erodiertechnik primarily serves toolmaking, mould making, mechanical engineering, the watch industry and medical technology. Production takes place on Sodick machines of the latest generation in air-conditioned rooms; rush orders are also processed on weekends.
