Aerospace Industry
As tough as it gets for Surface requirements
Highly efficient, ultrareliable engineering is just one of the challenges the aerospace industry rises to on a regular basis, which is why manufacturers expect their components and production processes to meet such stringent requirements. By 2050, Europe’s ACARE alliance aims to cut carbon dioxide by 75%, nitrogen oxide by 90% and noise by 65%.
A key factor in meeting those targets is to reduce engine friction, which in turn requires smooth functional surfaces.
Efficient design often implies very narrow tolerances and less scope for process variation, making stable, repeatable, fully automated production processes all the more important.
Leading OEM, TIER 1 and TIER 2 manufacturers in the aerospace supply chain rely on our innovative finishing solutions, which far outperform the conventional processes they used in the past.
OTEC’s mass finishing machines are designed for applications ranging from smoothing for minimal roughness (superfinishing or ultrapolishing) to rounding and/or deburring. On request we also develop other, highly customised applications.
SMOOTHING | POLISHING – STREAM FINISHING | DISC FINISHING
Ultra-smooth surfaces on assemblies such as compressors and gearboxes are indispensable for efficient engine operation. Our customised stream finishing (SF) and disc finishing (CF) processes smooth and polish to Ra 0.01.
With process speeds up to 24 times faster than hard-to-control, chemically accelerated mass finishing, OTEC machines rise to many a challenge not only more quickly but also at lower cost and with greater process reliability. What’s more, they do away with expensive, polluting, dangerous acids and materials.
In industrial manufacturing processes for compressor blades, vanes and blisks, our customers obtain roughnesses of ~Ra 0.15 with systems tailored to their requirements.
Smooth tooth flanks and rounded tip edges boost gearbox efficiency by minimising friction and Rpk values. Another specific of the stream finishing process is that it produces lubrication valleys, significantly reducing the risk of oil film breakage – and therefore wear – to guarantee safe operation. Our stream finishing process obtains roughnesses as low as Ra 0.07 µm on high-grade hardened gears.

CF SERIES
Years of experience have gone into our CF Series disc finishing machines, which are designed for rapid, flawless surface processing on bulk parts.
DEBURRING | EDGE ROUNDING – STREAM FINISHING | DISC FINISHING
After the primary or shaping manufacturing process, sharp edges, fraying or burrs must be removed from the workpiece. The edges can very often be rounded as required at the same time.
Processes that are tailored to the workpiece allow custom surface processing for bulk materials and piece goods using the OTEC mass finishing machines.
ADVANTAGES OF OTEC’S SURFACE PROCESSING
- Deburring and edge rounding in one process
- Improved handling and fitting
- Reduced risk of injury during assembly
- Components look and feel better
