Our customers are amongst the market leaders in aviation. This is why it is natural that we have to be leaders in our technologies, too, so as to enable cooperations as partners and to satisfy the requirements in terms of costs and quality.
Leistritz is involved in research and development projects in collaboration with universities and research institutes so that we always have our hand in on the latest basic developments. Our machinery is kept up-to-date and we regularly try out new manufacturing concepts.
A balanced mixture of experienced staff and young engineers guarantees the passing on of knowledge and rejuvenates our know-how with modern technological and organisational approaches.
Our customers develop outstanding technical components for their specific application cases. We support them in all phases of the product's life by providing manufacturing know-how. The focus here is on engineering. The use of simulation and optimisation tools as well as modern 3D machine programming are a matter of course today.
Forging for aero industry
We use precision forging to manufacture compressor blades with a thickness and profile tolerance of only a few hundredths of a millimetre. The gas duct with inlet and outlet edges and platforms on the foot and shrouding band are forged so precisely that no subsequent machining is needed to achieve a ready-to-install condition. This economical procedure is standard for almost all compressor blades from Leistritz.
During isothermal forging, the dies are heated to the same temperature as the forged part. This allows shaping at any rate without the forged part cooling down. This process sometimes also takes place in an inert gas or vacuum. This complex technical procedure keeps the shaping forces low and ensures an even, fine-grain microstructure with the resulting outstanding performance characteristics.
ECM - Electrochemical Machining
We use the ECM process to manufacture the most complex compressor blade profiles – a speciality of ours. ECM is a method whereby the material is removed without physical contact. We began to use this special method in series at the beginning of the 1970ies and have now manufactured more than 15 million compressor blades in this way. The Leistritz ECM process guarantees maximum precision and repeating accuracy for the production of difficult, 3D-twisted blades. Aerodynamic profiles with complex 3D geometries and elliptical front edges are also produced in one operation with an excellent surface finish.
We use the latest technologies for machining – to both manufacture engine aircraft components of bar stock and to finish forged or precision-cast components. Whether lathing disks and blisks or milling and grinding blades or structural parts – Leistritz always has the right solution.
