COMPANY

history

Driven by his inventive and pioneering spirit, Dr. Ernst Grob developed in the 1940s and 1950s the cold forming process that is successfully applied to the present day. In 1962 he founded a factory in Männedorf, Switzerland for building cold forming machines.

1962

During his time in Germany, Ernst Grob spent the 1930s focusing intensely on the development of cold forming machines for generating threads.

The idea of adapting that process to spline forming led him, already aged 69, to found yet another firm specialising in the manufacture of cold forming machines dedicated to forming splines in solid stock.

1962

In the 1950s, after handing over management of the Munich Machine Tool Works (today's GROB Works Mindelheim, Germany) to his son, Dr. Ernst Grob returned to Switzerland, intending to retire in 1962.
