Precision Processing

Diamond and sapphire are the typical jewel used for industrial parts, which make use of their hardness. However, the same hardness makes them impossible to process with an edged tool.
Orbray's unique core technology, “cutting, grinding and polishing”, lies in the processing of hard jewels.
In addition, to further develop our core technology, we have fused it with high technology such as laser processing.
This evolution of our core technology looks ahead to ever-advancing technological innovation, and serves as a driving force in developing our "Only One" products.
