WALTER has been writing grinding history since 1919. WALTER has developed from a small enterprise into an internationally active company with around 600 staff. Walter Maschinenbau GmbH owes its position in the market to the wealth of experience it has gained from years of serving its customers needs. Its former pioneering spirit is also reflected in its present-day products, and is impressively demonstrated by the quality and quantity of its innovations.


Founding of the company by Richard Walter in Düsseldorf under the name Walter Montanwerke.
Just four years later Richard Walter also acquires a small company in Tübingen and produces metal tools at both locations.
