After using Rosler drag finishing systems for a number of years, Airbus Helicopters knew just who to turn to for help with a new helicopter model.
We
took on the challenging task of finishing larger gear components for the new
design as well as incorporating expanded capacity for their existing helicopter
models, developing an innovative drag finishing system with automatic work
piece clamping and a clever work piece handling system.
Based
on numerous processing trials in our test center, Rosler developed an entirely
new drag finishing concept that meets all customer requirements. Flexible yet
robust, the new drag finisher is capable of finishing approximately 35
different work pieces made from special, high-performance steel alloys with
diameters from 40-800 mm and individual weights of up to 75 kg.
The aerospace industry demands high repeatability and adherence to strict production tolerances. As we discovered in Aerospace, Part 1, Rosler Metal Finishing’s surface finishing technology delivers the precision needed for aerospace components both large and small.
For complicated gear components, we turn to our drag finishing systems for exact results every time.
Small to medium size structural aircraft parts
Characterized by its sturdy design and numerous technical features, Rosler Metal Finishing’s drag finishing systems are ideal for high value and sensitive parts such as aerospace components that cannot touch each other during the finishing process.
Equipped with a rotary carousel featuring 2 to 12 spindles to mount the parts, work pieces are “dragged” through the media mass. The rotation of both the carousel and the spindles guarantee an even treatment of the parts. Drag finishing offers a metal removal rate that is up to 40 times higher than conventional vibratory finishing.
To this day, the surface of large structural
aircraft components is frequently finished by hand. This process is not only
costly, but extremely inefficient and hard to replicate with absolute
conformity.
Airplane Landing Gear
Rosler Metal Finishing is changing the notion that suitable mechanical finishing equipment is not available for large, structural aerospace components by offering mass finishing technology capable of solving this problem and providing fully automatic finishing of work pieces up to 30 feet long.
We kick off our Aerospace Series with an overview
of the cost-effective and mechanical finishing options Rosler offers for the
Aerospace industry.
Vibratory Tubs Offer a
Solution
Thanks to the development of large, powerful vibratory tubs manual deburring and grinding of large aircraft components can now be eliminated. The development of perfectly controlled mechanical finishing systems offers finishing solutions for applications where the biggest rotary vibrator, because of the size of the parts, might still be too small.
