Page Overview: Mechanical production

We are mobility visionaries.

Mechanical production.

Mechanical production of core engine components is one of the main processes at the Steyr plant. Production employees are responsible for manufacturing core engine parts, which are then fitted at other BMW Group plants. The combination of state-of-the-art systems engineering and experienced specialists guarantees the highest quality. The dimensional accuracy and quality of the machined parts is constantly monitored on an ongoing basis.

The engine core.

BMW engines face many demands: from power and dynamic performance to comfort and smoothness – every BMW customer has a right to expect these qualities. State-of-the-art systems engineering, highly-qualified employees and stable processes form the basis for our premium products. BMW produces its own core engine parts with the expertise that guarantees premium quality. Crankcases, crankshafts, cylinder heads and connecting rods are all delivered to the plant as moulding blanks. The work-pieces are turned, milled, drilled, polished and honed on ultra-modern production lines and in highly-flexible machining centres – transforming the raw material into a masterpiece.

Quality is the benchmark.

In mechanical production, the quality of machined pieces is constantly monitored on an ongoing basis and parts undergo spot-checks in the precision measurement lab. Machining accuracy can now be measured to a thousandth of a millimetre (µ: 0.001mm). For comparison, a human hair has a diameter of 0.05 mm.

Humans and machines.

Smooth management of millions of parts depends on a dense logistics network. Supplying systems with moulding blanks and timely delivery of finished components for engine assembly are expert tasks. Precision is assured by state-of-the-art machines and systems supervised by skilled operatives.
