In the field of aerospace engineering, precision and safety are paramount—particularly for critical Class-A components such as rotating engine parts. These highly sensitive components, whose failure could have severe consequences, demand not only exceptional process accuracy but also the highest levels of stability and traceability. With its state-of-the-art stream finishing technology, OTEC offers a groundbreaking solution to meet these challenges while significantly enhancing productivity.

OTEC’s finishing systems set new benchmarks by enabling seamless integration with production databases. This ensures that the systems always operate using precise, component-specific process parameters. Manual errors are eliminated, and scrap rates are drastically reduced. Given that sensitive components such as turbine disks can cost up to €60,000, this level of process reliability is invaluable. The technology is further enhanced by comprehensive traceability at the serial-number level, documenting every step of the process.

The process stability of OTEC systems is ensured by intelligent media management, which monitors parameters such as rotational speed, water flow, and compound dosing. Unlike outdated machinery, there is no need for constant adjustments to process times, as these remain stable. This makes the technology not only efficient but also low-maintenance.

A key competitive advantage of OTEC lies in its ability to process large and heavy components in an automated and reproducible manner. The SF-HP system, specifically designed for such applications, is a global leader and enables seamless integration into Industry 4.0 environments. This combination of technical innovation and industrial connectivity is unique and sets the benchmark for the next generation of manufacturing. For smaller components, the SF series also offers optimal solutions and can be integrated smoothly into nearly any process.

The success of this pioneering technology is demonstrated by numerous completed projects. For example, a renowned German manufacturer replaced older systems with OTEC solutions, resulting in significant process improvements. Approvals from major international OEMs further confirm the technological superiority of OTEC systems. By the end of 2026, it is expected that three of the world’s largest OEMs will have adopted OTEC systems for engine applications.

“Our technology has already been approved by leading aerospace companies. It not only ensures the highest quality but also reduces long-term costs by minimizing scrap,” said Adrian Kofler, Aerospace Applications Manager at OTEC.

OTEC also offers the capability to develop customized solutions tailored to specific requirements, making it an ideal choice for companies with unique needs. These groundbreaking advancements in the aerospace industry clearly demonstrate that OTEC technology will play a vital role in enhancing efficiency and reducing costs. With its innovative approach and unwavering focus on quality, OTEC will continue to lead the industry.

One of the biggest challenges in the industry is the ongoing decline in skilled labor qualified for manual processes. At the same time, the market demands absolute process reliability and more efficient production methods. OTEC addresses this with an automated and process- stable alternative to outdated systems. The trend toward digitalization and the reduction of manual labor not only opens new opportunities for customers but also ensures long-term competitiveness.

The development of cutting-edge turbine disk processes, carried out in close collaboration with an American OEM during the COVID-19 pandemic, underscores OTEC’s innovation and flexibility. Within just twelve months, a universal and validated process was established—one that today serves as a benchmark for the industry.
