PRECISION MACHINING
OF ULTRA-HARD MATERIALS

Since our founding, we have accumulated a wealth of experience and technology in complex, high-precision machining of a wide variety of ceramics and high-melting-point metals, aiming to be a niche leader, which is the origin of our company name.
We are continuously researching and investing in new technologies in order to deliver highest quality machining services to our customers. Moreover, by utilizing the technical data and know-how we have accumulated to date, we are able to design and develop machining tools to satisfy customers' needs even for difficult-to-machine products that would normally be very challenge to achieve. In the future, we will continue to respond to our customers' requests and contribute to cutting-edge technological innovations, keeping in mind our motto, "There is nothing that can be processed in steel that cannot be processed in other materials", and striving to be the best technical group in the world through relentless pursuit of excellence.

SHAPE MACHINING/3D MACHINING

What can be machined on steel can be machined on all materials

Using machine tools such as 3-axis milling machines and linear specification milling machines, we perform a variety of machining operations such as external shape machining, drilling, unevenness machining, grooving, and screw machining on difficult-to-machine materials. We are also capable of 3D machining of curved surfaces and three-dimensional shapes, as well as drilling holes in such special shapes. In addition, we also specialize in deep hole drilling on the side surface.

MATERIAL SOLUTION

UNLIMITED MATERIAL KNOWLEDGE

Making the right choice can make all the difference

Top Seiko offers material selection assistance service by recommending materials based on material property important for your application. Since we do not produce materials, you can count on our unbiased material knowledge to choose the most suitable material for your application. We offer not only materials from Japanese manufacturers but also from those outside Japan. We also have a wide variety of materials in stock for quick delivery. You can take advantage of our comprehensive precision machining service including material selection assistance & material sourcing for your product development projects! Moreover, there are many successful cases of material replacements which resulted in improving quality, prolonging service life, and increasing productivity / product yield. Let us help you, too!
