海德漢沿革
The company began as a metal etching factory that was founded in Berlin by Wilhelm Heidenhain in 1889. This factory manufactured templates, signs, graduations and scales. After the company was destroyed in World War II, the DR. JOHANNES HEIDENHAIN Company was founded in Traunreut by Wilhelm Heidenhain’s son. The first products were again graduations and price scales for the retail trade. Optical position measuring systems for machine tools were soon added to the program. At the beginning of the Sixties came the transition to linear and angle encoders with photoelectric scanning. These developments made it possible for the first time to automate many machines and systems in the manufacturing industry.
Since the mid-Seventies HEIDENHAIN has become an increasingly important manufacturer of numerical controls and drive technology for machine tools.
From the very beginning, the company had taken a highly technical direction. In order to secure the continuity of the company as well as its technical direction, Dr. Johannes Heidenhain placed his shares of the company in a foundation in 1970. This enables HEIDENHAIN today to invest extensively in research and development.
