Machining of large components

MMG offers the manufacturing of ship propellers, blades, hub bodies and other large components on a total area of 8,400 m².

The modern technical equipment of our workshop allows MMG to manufacture fixed pitch propellers with a maximum finished weight of 160 tons and a diameter of 11,6 meters.

Precise to a few hundredths of a millimeter

Even ship propellers of more than 11 m in diameter can thus be machined with an accuracy of a few hundredths of a millimetre. This precision is particularly important for the hub bore. Our specially developed balancing machine from MMG ensures that our propellers run perfectly.

State-of-the-art 5-axis machining centers

Several state-of-the-art 5-axis milling and boring machines are available for the implementation of the optimized propeller design. These special machines are dimensioned in such a way that they meet all current and future requirements for propeller size, shape and weight.

MMG’s high-end machining centers and computer-controlled five-axis milling machines guarantee maximum precision. They enable us to master even the most complex designs.

There is also a grinding shop with 5 semi-automatic grinding robots, a total of 7 enclosed grinding booths with high-performance exhaust air filters and integrated dust and noise protection.

Excellent craftmanship and years of experience

As perfect as machining technology is, it will not completely replace the experience and craftsmanship of our MMG employees. At MMG, state-of-the-art machining technology is paired with the excellent craftsmanship of our experienced employees. Even on the heaviest and largest castings, sensitive areas such as leading and trailing edges are still ground and polished by hand with the highest precision.

Technique for individual requirements

Centrifugal Casting

With the method of centrifugal casting we produce liners and bushes made from copper or aluminum alloys. The semi-finished products produced in this way are particularly suitable for the manufacture of highly stressed structural parts.
