07/22: A breakthrough on superfinishing of high loaded gears brings big cost savings into aerospace production

Whitepaper Aerospace

High loaded gearboxes, such as reduction, propeller and helicopter gearboxes, they are counted as the highest loaded gearboxes with the highest precision in design, validation and manufacturing. Many gearboxes in this application are designed as a planetary gear system that transmits the torque from the low-pressure turbine to the propeller, rotor or fan. With this gearbox design, many benefits such as fuel burn savings, engine noise reduction and engine operation cost reduction can be achieved.

07/22: ELECTROCHEMICAL SMOOTHING OF METALS USING ION-CONDUCTING SOLIDS IN WEAKLY CONDUCTIVE SOLUTIONS

Whitepaper Electropolishing

For applications in dental technology, it is very important to achieve a homogeneous, smooth surface without affecting the delicate components, e.g. side clasps of dental parts. Conventional polishing baths for smoothing cobalt-chrome dental parts can smooth the surface, but the result can be very uneven, de-pending on the shape of the workpiece. As an alternative, weakly conducting electrolytes with ion-exchanging solid particles based on styrene copolymers and sulfonated divinylbenzene have been available on the market for several years. This article draws a direct comparison between both methods, in terms of the electropolishing result and the surface quality achieved, using optical microscopy and roughness measurements.

01/22: GRATOWANIE I ZAOKRĄGLANIE DYSKU TURBINY

Whitepaper Aerospace

Dyski turbin i kompresorów posiadają gniazda w kształcie jodełki, w które montowane są łopatki turbiny. Standardowe metody produkcji tych gniazd montażowych to przeciąganie, cięcie drutem lub frezowanie. Ale te techniki powodują powstawanie zadziorów i ostrych krawędzi w gnieździe. Aby zapewnić bezbłędny montaż i zapobiec skaleczeniom, krawędzie gniazda i zamka łopatki muszą być pozbawione zadziorów i zaokrąglone określonym promieniem.
