Orbray Co., Ltd.

Since 1939, Orbray develops and manufactures core parts and products to meet a diverse range of needs in highly specialized industries. We produce diamonds, sapphires, and other industrial jewels, focusing on the precision cutting, grinding, and polishing of these materials.


Known for our made-to-order products, where we give our fullest attention to our customer's needs, we are proud of our master craftsmanship, which cannot be achieved through automation or machines alone. We have received high acclaim in a diverse range of niche markets, including telecommunications, semiconductors, robotics, precision equipment, and biomedical science.
