Ogura Jewel Industry Co., Ltd.

We are an established precision part manufacturer with nano-level machining accuracy. 

Our main lines of business are precision machining of industrial jewels and high-hardness, brittle materials, and diamond tool development and manufacturing. We supply these products to many companies in Japan and overseas (Europe and Asia) operating in a various industries including machining tools, semiconductor equipment, analyzers, medical devices, industrial meters, and measurement devices. Our company has been accumulating insight and experience on industrial jewel parts for over a century since our establishment in 1894. We have established original micromachining technologies by combining advanced precision machining technology and the latest machining techniques. This has resulted in our nano-level shape accuracy with regard to machining record styluses (stylus tip processing).

[Company strength]
Our company has been manufacturing industrial jewel parts for over a century since our success in jewel processing (for torpedo sighting) in 1894. Jewel bearings have been our main products since our establishment. We later started to manufacture sapphire and diamond styluses for recording and playing records of music after the war when the record business was growing. We now provide precision products to various industries by making use of the excellent properties of jewel materials and the manufacturing technologies we have inherited. Our knowledgeable staff members clarify customer problems and requests, and we work together to create optimal solutions and specifications for the use and environment in the form of collaborative manufacturing. 



[Business description]
Our main businesses are (1) precision machining of industrial jewels and high-hardness, brittle materials, and (2) diamond tool development and manufacturing. We supply these products to a wide range of industries, including machining tools, semiconductor equipment, analyzers, medical devices, and industrial meters and measuring instruments. We manufacture products according to specifications requested by our customers. 

[Industry]
Precision part manufacturing (industrial jewel materials; high-hardness, brittle materials)

[Strength of products/technologies]
Our company has established original micromachining technology by combining advanced precision machining technology and the latest machining techniques. Our core technology is tip processing, which is an advanced form of record stylus machining, and we have achieved nano-level shape accuracy. We have further improved the machining techniques applied to our old business of jewel bearing production. We now apply them to a wide range of products as high-precision boring technology with µm-level accuracy. We excel at processing industrial jewel materials and high-hardness, brittle materials, but we are willing to try new special materials. 

[Representative's message]
We are a pioneer of industrial jewel processing, and our company has been nurturing advanced technologies for over a century. We will continue to work hard to help raise the standard of living by continuously pursuing advanced micromachining technologies and nano technologies in our manufacturing operations. 

[Company structure for market development/overseas expansion]
We have expanded our organizational framework to better satisfy customer needs. Sections for processing and development, processing and technology, production technology, and product technology in our technology department provide detailed, comprehensive support to customers. Our overseas sales activities are conducted at our site in Thailand, and target customers in India, Singapore, Malaysia, and Indonesia. Major customers in China are supported by the staff at our Shanghai site. We have sales agencies to provide services in Korea and Taiwan.
