Dr. Johannes Heidenhain GmbH Founded 1948 Headquarters Traunreut, Germany Products measuring systems, numerical controls Employees 7000 Website www.heidenhain.com Dr. Johannes Heidenhain GmbH is a privately owned enterprise located in Traunreut, Germany that manufactures mechatronic measuring devices for length and angle.
These linear and angle encoders are built for use in automated machines and systems, particularly in machine tools.
History
Encoder ROD 420
The company began as a metal etching factory founded in Berlin by Wilhelm Heidenhain in 1889 that manufactured templates, company plaques, product labels, and scales.
In 1928 Heidenhain invented the Metallur process. This lead-sulfide copying process made it possible for the first time to make exact copies of an original grating on a metal surface for industrial use. By 1943, Heidenhain was producing linear scales with accuracy of ± 15 µm and circular scale disks with accuracy of ± 3 angular seconds.
After World War II, in 1948, Dr. Johannes Heidenhain company founded the present company in Traunreut.
Its invention of the Diadur process enabled it to apply very fine structures of chromium on suitable substrates, such as glass.
The Diadur process was the basis in 1952 for adding optical position measuring devices for machine tools to the product program. These were followed in 1961 by photoelectrically scanned linear and angle encoders.
In 1968 Heidenhain manufactured its first digital readouts.
The first Heidenhain numerical control was launched in 1976.
In 1987, a linear encoder series operating on the principle of light interference was introduced. It permitted measuring steps as fine as one nanometer.
According to Heidenhain, in 2006 the company had regional sales locations in 43 countries and employed about 7,000 people, 2,600 of whom worked in the main facility in Traunreut, Germany.
By the end of 2006 the company had manufactured about 10.5 million linear or angle encoders, 420,000 position displays and nearly 200,000 CNC controls.
