Making the Impossible Possible
Grinding and Cutting Machining Technologies
We provide custom machining of ultra-precision components using ceramics, refractory metals, and quartz glass.
Our technologies and expertise have been refined through work across a wide range of industries, including semiconductors, aerospace, energy, automotive, and medical. This accumulated knowledge is the source of our competitiveness.
Even for complex geometries that were previously considered impossible, we are able to achieve high-precision, high-quality mass production.
Why Choose Us
Extensive Experience in the Semiconductor Industry
Including Products with World-Class Market Share
Since its founding in 2001, Top Seiko has contributed to a wide range of industries through the prototyping and mass production of custom mechanical components.
In particular, we have built extensive experience in the semiconductor industry. We supply critical components—including electrode parts with world-class market share—to major semiconductor manufacturing equipment manufacturers in Japan and around the world. These components are designed to withstand demanding operating environments.
Advanced Expertise in Difficult-to-Machine Materials Including Ceramics and Refractory Metals
“Anything that can be machined in steel can be machined in other materials” is our guiding philosophy. Based on this principle, we have accumulated specialized machining expertise in difficult-to-machine materials such as ceramics, molybdenum, tungsten, quartz glass, and composite materials.
We are also committed to introducing state-of-the-art machine tools and developing our own cutting tools and fixtures, striving to build one of the most advanced precision machining environments in Japan.
Sales Staff with Extensive Knowledge of Materials and Precision Machining
Providing Accurate and Prompt Support
