Since its establishment in 1939, Adamant Namiki has been consistently manufacturing industrial jewel parts.
We have a variety of products in order to meet our customer’s needs.
Our company utilize hard jewel materials such as a diamond, sapphire, and ruby which substantially reduce abrasion due to friction, and contribute to la longer operating life of the machine and the product itself.
As a result of the permanent focus on improving the processing of hard-to-cut materials, our core expertise is now able to process various types of hard-to-cut materials with high precision and best-in-class QCD.
We integrate cutting edge technology with our unique hard materials processing methods.
We continue to offer unique products, including jewel bearings, ceramic watches, sapphire watch cases, and UV-emitting sapphire.
While we focus on single crystal sapphire wafers for high frequency and LED use, we also support the production of various shapes, such as plates, tubes, and jewelry.
Precision Nozzle, Needle
High precision and abrasion-resistant, our nozzles are made to meet custom requirements with materials such as diamond, ruby or ceramic.
Winding nozzles and bearing rollers are widely used for electric motors in cameras, cellular phones and other equipment.
We provide a variety of parts for medical equipment industries, which require safety and accuracy.
Analog Record-related Products
Our precision machining technology enables us to manufacture parts such as diamond record styluses and cantilevers.
Measuring Instrument Jewelry Bearing
Ruby and sapphire bearings have a long life due to their wear resistance. We have been manufacturing bearings since our foundation.
We manufacture ultra-high precision core pins per end user’s specifications using our ceramic injection molding technology.
We offer standard gauge sizes and specifications for the inspection of ferrules and sleeves and can also manufacture custom configurations and sizes in 0.1µm increments.
Our diamond scribers ensure a narrow and deep scribing line and minimize adverse impact on the wafer.
A multi-layer glass ceramic substrate which is co-fired with low resistance metal conductors at a low firing temperature (less than 1000℃).
Microwave Power Amplifier
The world's first ultra-compact microwave power amplifier, which uses GaN semiconductor devices and LTCC substrates to operate.
