2 Milestones For more than 80 years BERGER has been building grinding and polishing machines designed primarily for the machining of cutlery, hand tools, and related components. Heinz Berger and Karlheinz Berger 1930 The idea to manufacture machines for cutlery actually came at an earlier date. In 1928 Heinz Berger began working as an engineer at the Julius Berger Company, which had been founded by his father and continues to produce gardening tools to this day. Grinding was and is a key process in the production of cutlery items and hand tools. The manual machining that was used at the time required a great deal of skill and physical exertion After 1950 design and manufacture of grinding machines were advanced, in addition to the production of gardening tools, based on the experiences made in their production facility. Grinding machine The machine manufacturing branch, which had developed well over the years, was separated from the Julius Berger Company in 1957 and continued by Heinz Berger as an independent company, called the Heinz Berger Maschinenfabrik. Ongoing development in collaboration with the customer vertical grinding machine of the series DG-CNC Rapidly increasing product demands required greater production capacity. In 1959 the plant was moved from its location in Berghausen to the new facilities at the Kohlfurther Brücke. It then became possible, as a result of new developments in the product line, to expand to the global marketplace. Machine exports played an important role at the time and have increased to 70% of the business today. 2

3 Progress and innovation After the death of Heinz Berger in 1970, his son Karlheinz Berger assumed control of the company. The years following saw the completion of new machine designs with mechanical and hydraulic drive technology. The number of machines with automatic part loading is increasing each year. Since the beginning of the 90 s, the third generation has become involved in the company with daughters Claudia and Heike and sons-in-law Dr.-Ing. Andreas Gross and Marco Chiesura. New machine designs based on CNC technology contribute to a product line today of more than 40 models with up to 7 servo axes The integration of innovative technologies, such as robotic automation and modern gaging processes, continue to be company priorities. Based upon production demands, robotic assemblies with 4-7 axes are implemented. Initially used to automatically feed parts to grinding and polishing machines, robots are now used to grind and polish parts. Additional processes continue to be developed as a result of the opening of the Center for Robotic Applications. Marco Chiesura and Dr. Andreas Groß In the area of drive technology, servo motors on machines are more commonly replaced with state-of-the-art linear motors, which provide reduced cycletime increased availabilityand are maintenance-free, and extremly fast speeds. Continuous development and design enhancements are made possible by a staff of highly qualified employees, who are committed to find advanced engineering solutions and place a high priority on their ability to develop customer-specific machining applications. today Head office in Wuppertal (Germany) As a result, the Heinz Berger Maschinenfabrik has become a global partner in the production of cutlery items, hand tools, machine knives, surgical instruments and circular knives, and provides customer service from its Cronenberg location. The company currently delivers machines to more than 70 countries and is represented throughout the world. Berger L.L.C. was formed as an independent division in 2003 to provide sales and service support within the United States. As the Berger Group has been completed by more companies, the group is more than ever a competent partner for metal processing. Worldwide presentation of the Berger Group on trade fairs 3
