Processing technology that combines precision, quality, and speed.

Rintian Giken balances precision, quality, and speed in the processing of close-tolerance rings. We can handle thicknesses around 10mm and outer diameters up to φ400, achieving high-quality finishes even with difficult-to-machine materials like titanium and SUS. We flexibly accommodate everything from single-item prototypes to mass production, meeting the high demands of the semiconductor and optical fields. 【Features】 - Geometric tolerances from 0.01 to 0.05 - Capable of processing thicknesses around 10mm and outer diameters up to φ400 - Compatible with titanium, SUS, aluminum, and brass - Inspections at 1μ units using a three-dimensional measuring machine *For more details, please refer to the materials. Feel free to contact us as well.
