Since the acquisition of our first Wickman, EDM Preci-Spark has strived to stay at the forefront of the process technology through innovation and investment. This process still delivers cost-effective solutions in many applications, multi-head and multi-channel generators enable high levels of production throughput whilst maintaining part to part repeatability. Across our 6 manufacturing facilities we have 125 electro-discharge machines available for sub-contract work. This extensive portfolio of machine tools covers almost all applications, when required we have the expertise to build special-purpose machine tools and generators. Facebook Copyright by JHA 2011.
