Top Seiko Co., Ltd. offers the most advanced CNC machining services for all these ultra-hard but brittle materials such as Ceramics, Glasses and Refractory Metals such as Tungsten, Molybdenum and Tantalum.

We machine not only Machinable Ceramics, but also other Technical Ceramics such as Alumina, Aluminum Nitride, Silicon Carbide, Silicon Nitride, and Zirconia. We are very passionate about machining newly developed or extremely hard materials. We even machine CMC(Ceramic Matrix Composites)* for applications in space.

We employ a variety of CNC machining centers including high precision 5-Axis Control Vertical Machining Center and high speed Linear-Motor Machining Center. With experienced engineers and machine operators, we machine these ultra-hard materials to extremely tight tolerances.

Material selection assistance is available. Let's make your part more Cost-Effective and High-Performing!

Our sales engineers will help you find suitable materials based on your application needs as well as target price. In many cases, parts made of a material we propose to our clients offer longer service life which can result in lower costs, reduced maintenance and less down time.

*CMC(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.
