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.
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.
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.
Rapidly increasing product demands required greater production capacity. In 1959 the plant was moved from its location in Berg-hausen to the new facilities at the Kohlfurther Brücke. It then beca-me 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 busi-ness today.

Head office in Wuppertal (Germany)
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 hydrau-lic 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 auto-mation 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.
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 com-mitted to find advanced engineering solutions and place a high priority on their ability to develop customer-specific machining applications.
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.

• shape of the workpiece (forged, conical, or flat)
• variety of workpiece shapes / dimensions, that should be processed
• integration in the preceding stage of production (e.g. stamping) or subsequent processing (e.g. polishing, dry-fining)
• in which way the pieces are orientated (e.g. disordered in a glide grinding line)

Strong partners
under one roof ...
The names Heinz Berger, Hau-schild, August Nell and Julius stand for highest quality in the field of machining and refining metal coils and tools, e.g. house-hold and machine blades, cutting tools, surgical instruments, cast or forged tools. Their in-house robotic capabilities provide solu-tions to automation and process integration tasks.
Trend-setting innovations in the fields of robotics and CNC machines for grinding and poli-shing tools, as well as state-of-the-art technology for strip edge trimming by metal-cutting and surface finishing, are available for coil stock and tools that demand high quality.
The first automatic grinding machines from Berger in 1957, the development of the Julius edge trimming machine in 1980, the first CNC controlled double- scallop polishing machine by Hauschild in 1987, the use of more than 300 robots for automating Berger grinding machines since 2000, as well as Nell’s develop-
ment of the BSM 3000 CNC grin-ding machine for micro-grinding coil stock with camera control – all important milestones for the Group and key driving forces for the metalworking industry.
Thanks to a broad product line, the synergistic effects in our engineering, R&D and production departments, and a competent customer service team, the Berger Group provides complete solutions – particularly for custom requirements – all from a single source.
