Aerospace-grade precious stones (alumina bearings)
Achieving both lightweight and high precision. Active in the aerospace field.
In the aerospace industry, reducing the weight of aircraft is essential for improving fuel efficiency and performance. At the same time, high reliability and precise operation under harsh conditions are required. The lightweighting of bearing components is a crucial factor in reducing the overall weight of the aircraft and enhancing fuel efficiency. Our precious stone (alumina bearings) achieves high wear resistance and high dimensional accuracy, contributing to weight reduction and improved reliability in the aerospace field. 【Application Scenarios】 - Aircraft engine components - Precision instruments for space exploration vehicles - Bearings for air traffic control systems 【Benefits of Implementation】 - Improved fuel efficiency through weight reduction - Enhanced reliability of equipment due to high-precision operation - High durability under harsh conditions

The area where Citizen Fine Devices demonstrates its strength is in the realm of functional components that require small size, precision, high accuracy, and high detail. We believe that our mission is to continue providing high-value-added microdevice products by leveraging the unique technologies we have developed over many years. Utilizing metal processing technology rooted in watch manufacturing, we have consistently supplied small, high-precision components to our customers for many years through a fully integrated production line that encompasses process design, machining, assembly, and functional testing, along with the unique development of our own processing machines. Additionally, mass-producing components with high precision and efficiency using brittle materials is also one of our core technologies. By integrating material technology with ultra-precision machining, thin-film technology, and bonding technology, we produce not only high-precision components such as ceramics and quartz but also high-quality functional device products like liquid crystal devices and sensing devices. Continuing to provide high-value-added products to the market is a significant dream for our employees. We will contribute to the creation of new value through manufacturing driven by the challenge spirit of each individual, working towards the realization of that dream.
