Center of Excellence: Bundled competences

If you can do something particularly well, you should do it even better. We take this principle to heart and bundle our know-how for certain components and products in Centers of Excellence. Two of these competence centers are already operational for the repair of engine parts – and more are planned to be set up soon. Our center for fan blades is very well established and has already made a name for itself in the market. The new Competence Center Cases is dedicated to significantly reduce the turnaround times for these unique and very expensive components.

“An engine case can have the same service life as an engine. We always work hard to save and repair these cases.”

Marcel Rose, Head of Competence Center Cases

 
It's all about cases

Everything in one place

Engine casings are not only costly but are very special components in many other respects too. They are subject to high stress levels during use and thus have a vast need for repair. They are very individual – even if the part number is the same, each component is unique – and thus their repair requires similar complex methods. In addition, our customers in general also want the same casings back in their engines. Consequently, every day counts in terms of turnaround time.

 

All this made engine cases perfect candidates for us to establish a special place for their maintenance. With the new Competence Center Cases in our Hamburg facility, all the equipment for the repair of engine housings is located in one place. This not only saves valuable time, but also bundles our competencies, thus facilitating the development of new processes and repair methods.

 
A spa for engine housings

Start of treatment

We treat worn out engine cases just like a stressed person recovering in a spa. When engine casings in need of repair arrive at our competence center, they will be overhauled in a succession of dedicated stations. The treatment starts with a thorough cleaning and a detailed inspection for damage using a crack test. In the findings area, an exact assessment is then carried out. Once the diagnosis is made, reconditioning of the engine casing starts immediately.

 
X-ray center

The inner values count

Some cures need to go more than skin deep. To detect cracks in engine cases, X-ray is the method of choice. Therefore we invested in a state-of-the- art X-ray center to speed up the findings process and enhance the quality. In the X-ray cabin, the defective housing is positioned on a height-adjustable and rotating table and is x-rayed by two freely movable arms. Automated and with an all-round view of up to 360 degrees, 36 images are generated in just ten minutes. The imaging is monitored in real time so that the position of the parts can be varied. This allows to always obtain the optimum viewing angle. A thorough evaluation of the images enables us to determine the right remedy for each individual engine case.

 
Flexible processes

Back to service quickly

The workstations for machining and manual operations are next in this closely connected wellness treatment. Since the dimensional tolerances for engine housings are very tight, extremely precise work is required here. Like the preceding and following process steps, these stations are optimally integrated in this special spa's floor plan. For example, the Competence Center Cases has a small painting booth for the application of corrosion protection paints and a dye penetration test station for smaller areas. And there is always a specialist around to take care of these valuable parts on the spot.

In this way, the engine casing undergoes its retreading station after station. The efficient and proven process established in the Competence Center Cases avoids unnecessary transport routes and thus shortens turnaround times. So, while many an engine housing would certainly like to stay a little longer for this treatment, their owners are pleased to have them back on duty quickly.
