Precision Processing for Fast Bikes with SINUMERIK

To guarantee perfect workmanship and the highest possible product quality, BMW uses five-axis machining centers equipped with Sinumerik 840D sl and a range of new user interfaces for machining operations in its Berlin motorcycle plant.

BMW motorcycles enjoy an outstanding reputation around the world for their reliability, quality, performance and safety. This is not achieved by chance, however. BMW’s motorcycle plant in Berlin uses around 50 machine tools to create numerous key components on-site, from frames and valve shafts to connecting rods and cylinder heads. Among these tools are Grob’s horizontal five-axis G550 machining centers equipped with Sinumerik 840D controllers, which are used in the manufacture of cylinder heads for flat and 4-cylinder engines.


One of the major reasons for choosing the G550 was because it was equipped with a Siemens CNC. Thanks to previous positive experience with Siemens, the BMW manufacturing specialists in Berlin already employ technology from Europe’s market leader for 90 percent of their controllers.
This allows both operators and tool setters the flexibility to work on almost all the machines in the plant. Other key requirements noted in the specification were adequate space for manufacturing all relevant components, the highest levels of precision and surface finish, compliance with predefined cycle times, and the ability to reuse all current tools and equipment.
