With it’s ultra-modern machining centers MMG meets the highest demands in machining propellers and special castings. Perfection down to the last detail.
After extensive investments, MMG offers the manufacturing of ship propellers, blades, hub bodies and other large components made of copper alloys 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.
Even ship propellers of more than 11 m in diameter can thus be machined with an accuracy of a few hundredths of a millimetre. The same precision is of course applied to the hub bore, too. MMG’s specially designed balancing machine ensures that the propellers run perfectly true.
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.
In addition, MMG’s total 7 separated grinding stations are are completely redesigned grinding with high power air cleaner and integrated dust and noise abatement system.
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.
Whether container ships, tankers, bulk carriers, supply ships, cruise ships or naval vessels – MMG designs and manufactures propellers of up to 160t and 11.6m in diameter for all ship classes and sizes.
The innovative MMG Energy Saving Cap (MMG-Escap®) enables ship owners to increase the efficiency of their propulsion system by up to 3 %. The Escap® has an elaborate fin design which straightens the hub vortex and reduces torque loss.
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.
