About us
Ronald Menz Erodiertechnik in Halle (Westphalia) is a contract manufacturer specialising in erosive metalworking. The range of services includes wire EDM on six FANUC machines, small-hole EDM on two CNC machines, as well as CNC turning of serial parts, CNC milling and surface grinding. EDM is possible in all electrically conductive materials regardless of their hardness, above all steel, aluminium, copper, brass and carbide. The employees have many years of experience in tool and mould making. On request, the complete production of parts and assemblies is handled from a single source. Customers come from the tool, mould and mechanical engineering sectors as well as the automotive and furniture industries; pickup and delivery are available on request with the company's own vehicles.
