Aerospace, Part 3 – Drag Finishing for Airbus Helicopters

The aerospace industry demands high repeatability and adherence to strict production tolerances. As we discovered in Aerospace, Part 2, Rosler Metal Finishing’s drag finishing systems produce exact results every time.

Airbus Helicopters

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.

AEROSPACE, PART 2 – Innovative Finishing for Aerospace components

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.

Consistent, Repeatable, Economical Surface Finishes

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.

Aerospace, Part 1 – Cost-Effective, Mechanical Finishing for Large, Structural Aircraft Components

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.
