Precision Machining Services for Ultra-Hard Materials

“Many precision parts have been made in common metallic materials. But we machine exotic hard materials and make the same parts.”
With that motto, Top Seiko has specialized in ultra-hard materials such as advanced ceramics, glasses, refractory metals, and newly developed high performance materials like composite materials. Based on the machinability characteristic of each material and the complexity of the shape of the part, we determine the most suitable manufacturing method using physical and chemical approaches.

We are also an expert of designing machining tools that can maximize the productivity while maintaining the highest quality of products. Most of these tools are produced by tool-manufacturing companies according to our specifications. If not, we make them by ourselves.

We are continuously researching and investing in new technologies in order to deliver highest quality machining services to our customers. In addition, we regularly carry out test machining to collect data to expand our capabilities even further.
