We will finish samarium cobalt magnets, which are difficult to process, with high precision using our long-developed brittle material processing technology.
Samarium-cobalt magnets have a high Curie point of 800°C and are resistant to rust; however, they are considered brittle and difficult to process compared to neodymium magnets. Our company specializes in brittle processing technology to produce small cylindrical magnets with an outer diameter of less than Φ1.5 mm, with the smallest being Φ0.7 mm, while minimizing chipping and cracking. We can deliver stable, high-quality magnets finished to an internal and external tolerance of ±0.005 mm. With our long-established technology and skills in material crushing, mixing, molding, sintering, processing, and inspection, we can meet our customers' needs to the fullest extent. We can also accommodate plating treatments upon request.

Company information
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.
