BMW Motorrad: USES JUNKER JUCRANK FOR VARIETY OF GRINDING OPERATIONS

摘要

BMW Motorrad uses the JUCRANK non-cylindrical grinding machine for different grinding operations on boxer crankshafts. These are assembled into the latest BMW two-cylinder boxer engines for efficient motorbikes. Impressed by the level of precision and extensive experience in developing CBN high-speed grinding machines, BMW Motorrad has been putting their trust in the Junker grinding experts for more than three decades, with 45 machines at five sites worldwide. In-process measuring systems guarantee high process reliability and dimensional accuracy. The fully automated system measures the exact workpiece data and adjusts automatically during the grinding process if needed. This procedure reduces auxiliary process times and increases output.
