Top Seiko specializes in complex and precise machining of custom ceramic machined parts.

With EDM*1, grinding, slicing, turning and CNC machines, we offer ceramic fabrication service in the most cost effective methods.

With our extensive experience with ultra-hard but brittle materials and latest machines such as high precision 5-Axis Control Vertical Machining Center and high speed Linear-Motor Machining Center, we offer precision fabrication of almost any kind of Ceramics. Even CMC (Ceramic Matrix Composites)*2, one of the hardest ceramics, can be machined by us! That is why we have customers in Aerospace Industry.

Our drilling capability enables to achieve dimensional deviation between precision holes within 2 microns in Alumina material.

Looking for Ways to Reduce Weight and Power consumption? Or Ways to Increase Manufacturing Yield?

Ceramics can be the solutions. Just replace conventional metals or Resin Materials to Ceramics may make a drastic change in performance of your critical parts. Let us help you select best materials for your applications!

Each Ceramic has unique characteristics. Generally, they have high hardness, excellent heat resistance, good electrical insulation, and low thermal expansion. Some ceramics like Aluminum Nitride and Silicon Carbide have high thermal conductivity. Zirconia, on the other hand, has low thermal conductivity as well as noticeably high wear quality, and is often used for pistons, cylinders, sleeves and clamping parts. We have intensive experience of making these critical parts that require extremely high wear resistance as well as tight tolerances.

*1 EDM: Electrical Discharge Machining. Using electrical sparks, material is removed from the work piece(electric conductor) to obtain a desired shape.

*2CMC(Ceramic Matrix Composites): A fiber-reinforced ceramic composed of SiC fibers and SiC matrix. It is light-weight, high-temperature strength, and high durability material developed as a next-generation material for aero-engines.
