History

SUPER PRECISION was founded by Henry and Franklin Hardinge in Chicago, USA. Known for ultra-rigid machines for hard turning, the brand would later become a legacy name within the group.

HAUSER – founded by Henri Hauser in Biel, Switzerland, became a benchmark in ultra-precision jig grinding.

KELLENBERGER was founded by Leonhard Kellenberger in St. Gallen, Switzerland, where the first universal cylindrical grinding machine was developed. The company quickly established itself as a leader in precision grinding.

VOUMARD was established in St.Imier, Switzerland. Known for its innovative internal grinding solutions, the brand would later pioneer CNC technology in this field.

With the introduction of the first hydraulic universal grinding machine, KELLENBERGER significantly advanced automation and precision in grinding technology.

TSCHUDIN was founded in Grenchen, Switzerland. The brand gained recognition for compact external cylindrical grinders and modular FLEX automation systems.

KELLENBERGER expanded its expertise to include tool grinding machines, further strengthening its position in universal cylindrical grinding.

USACH was founded in Elgin, Illinois, USA. The brand focused on grinding hard-to-machine materials using advanced multi-axis and in-process measurement technologies.

VOUMARD introduced CNC-controlled internal grinding machines, setting new standards for precision and flexibility.

KELLENBERGER was acquired by Hardinge, enhancing the group’s global footprint in precision grinding.

VOUMARD was fully integrated into the KELLENBERGER Group, complementing the portfolio with internal grinding expertise.

KELLENBERGER incorporated VOUMARD’s internal grinding technology into its core offering, expanding its high-precision capabilities.

KELLENBERGER separated from Hardinge and became independent. At the same time, USACH and SUPER PRECISION were integrated, bringing together decades of expertise in high-precision grinding under one roof.
