Hardinge Kellenberger AG was founded in 1917 by Mr. Leonhard Kellenberger. Its earliest success resulted from its universal grinding machine, and the company participated in its first machine exhibition in Basle, Switzerland in 1919. A year later, it introduced both a surface grinding machine and a special grinding machine for the rebuilding of automobile engines. Throughout the 1920’s, 1930’s and 1940’s, Kellenberger gradually grew as the company introduced a fine-boring, honing and crank-shaft grinding machine, a tool and cutter grinder and its first hydraulic universal grinding machine. Sales during that period largely occurred in Switzerland and Germany. In 1956, Mr. Edgar Kellenberger assumed responsibility for the company. Under his leadership, the company was successful by regularly updating its universal cylindrical and cutter grinding machines and by expanding the export of its products. By the late 1970’s, Kellenberger had worked with the Swiss electronics manufacturer Grossenbacher to develop a numerically-controlled system for its machines. In 1989, the third generation of the Kellenberger family assumed responsibility for the company when Mr. Jürg Kellenberger was appointed Managing Director. The company continued to grow and was acquired by Hardinge Inc. in 1995. Five years later, Hardinge added to its Grinding portfolio by purchasing Jones & Shipman, Hauser, Tripet, Voumard and Tshudin.
