We would like to introduce the various "Quality Assurance Systems" of Nakayama Precision. The "In-Process Inspection System" involves the operator measuring the products processed at each stage and recording the measurement values in the in-process inspection sheet. We thoroughly implement in-process inspections to ensure that defective products are not sent to the next stage. Additionally, in the "Improvement Activity System," we hold an improvement committee once a month, separate from regular meetings, aimed at enhancing customer satisfaction, reducing man-hours, minimizing errors, and improving yield. We strive for further improvement through proposals and ideas for enhancements. 【Quality Assurance System】 ■ Quality Inspection System ■ In-Process Inspection System ■ Research System ■ Training System ■ Improvement Activity System *For more details, please refer to the related links or feel free to contact us.

Nakayama Precision Co., Ltd. has been contributing to society as a carbide processing manufacturer since its establishment in 1969. "Skilled hands, eyes, and engineers" With this motto in mind, we strive to cultivate excellent talent and acquire the latest processing technologies, always aiming to produce high-quality products. No matter how advanced the machine tools are, they cannot produce truly good products on their own. This is our belief. Only with the skill of experienced individuals who can master those machine tools can we create precise products. Highly skilled craftsmen not only use their hands but also observe with their eyes, confirm sounds with their ears, and sense the heat of the machines to assess the situation, processing intricate and high-performance products with an accuracy of just a few microns. By actively introducing the latest NC equipment, including CAD/CAM, on top of this skilled human craftsmanship, we respond to the diversifying user needs such as small lots of various types and short delivery times.
