Our main products include the polishing of super hard round bars and the processing of super hard tools. Super hard round bars are used for drills that create holes in printed circuit boards and cutting tools for metal substrates, while super hard tools are cutting tools used for molding molds and processing parts for various products such as cars and mobile phones. At Kobayashi Super Hard Polishing, we have responded to a wide range of customer needs, from a single prototype to mass production with "high quality," "low cost," and "short delivery times" through automation. Furthermore, in recent years, we have been actively supporting our customers by responding quickly and carefully to requests for traceability related to quality control and environmental issues in the domestic manufacturing industry. In this ever-evolving world, we are constantly striving to improve and enhance productivity to meet our customers' needs. For more details, please contact us or download our catalog.
