Tool Management System
Tools, such as drills and lathe cutting tips, are indispensable for machining. In particular, many different tools are used in low-volume, high-variety production; as a result, tool management is extremely important for product quality and cost management. At Nagatsu, each tool holder has an IC chip embedded in it, enabling computer management of tool locations, lives, offset values, and other details, for shorter tool changing times, reduced tool costs, and consistent product quality.
