After 30 years of service at Vollmer Werke Maschinenfabrik GmbH in Biberach, Germany, Josef Rieger has retired from operational responsibilities over the company. He will continue to work for the Vollmer Group on a consulting basis.

Vollmer is known for its leadership role in the field of sharpening machines for saw blades and eroding machines for precision tools. A large measure of this success is given to the strong commitment and entrepreneurial skills of Rieger.

With the retirement of Rieger, two new managing directors have been appointed. Siegfried Knüpfer has spent 20 years in international consulting and management positions in both mechanical and production engineering, and previously was managing director of Boehringer in Göppingen, a member of IWKA AG. Stefan Brand has held a number of high-responsibility industrial posts, lastly as head of product development at Gildemeister Lathes in Bielefeld.
