The potter's wheel was the beginning of lathe-turning technology in Japan, and with the Japanese “Spirit of Craftsmanship” has since developed into nano-scale control precision lathes that uses low-cost, highly sophisticated multi-axis control automation systems, and, making use of all this manufacturing control technology, it is not an exaggeration to say that our product aggregate is at the pinnacle of the metal manufacturing world.
We at Yamamoto Metal Industry have persevered since the establishment of the company in striving to ensure the improvement of precision, and with timely investment in the future and optimization of QCDE, will constantly continue to deliver new innovation and pioneer new products around the clock, making home the Japanese “Spirit of Craftsmanship” not only to Japan but also to the world.

Factory 1: Bar Work (Blank and Finishing Process)
Making full use of our Multifunctional swissturn, we produce products like hard disk drive spindle motor hubs, automotive mechanical seals, polygon scanner motor parts, etc. from a variety of materials. We also have the proper facilities and processes for the making of blank parts to parts with one-sided or double-sided finishes.
Main Processing Diameter: Cylindrical bar φ6 - φ42
Factory 2 and Factory 3: Finishing Process (Last Finishing Process)
Affordable high-precision products are produced in large quantities by lines of precision lathes automated by robots and palletizers, supported by expert machinists using special cutting tools. A wide range of processing is possible not only for mass production but also for small-lot production and prototype development.
Adhering to the clientﾕs quality specifications, a visual inspection by magnifying glass and microscope is carried out on all outgoing shipments. Quality is 100% assured.
Lot-tracking is common practice in the industry, and all our outgoing shipments are tagged for tracking the product unit from raw material to finished product. Packaging, including for shipping by sea, is done according to client specifications, and has been praised by our clients for its reliability.
Although the mass production of hubs is currently in our flagship product, we also offer various super-precision high-quality components for prototype and small-lot production, at a low cost and quick delivery.
