Big work in the microscopic world
Precision processing technology that responds to the diversification of manufacturing
Since our founding in 1894, we have been engaged in industrial jewel processing. Gem materials such as diamonds, sapphires, and rubies can form sharp edges characteristic of single crystals. Taking advantage of these characteristics, we have consistently refined our micro and precision processing technologies and delivered products that meet the needs of the times.
