Company information
The tool used for generating cutting of gears, which are the foundation of mechanical elements, is called a hob cutter, and traditionally, high-speed steel has been widely used as its material. In 1961, Izawa Technical Research Institute became the first in the world to manufacture and commercialize hob cutters made from cemented carbide. Japanese manufacturing technology was said to be at a top level, and during the period of economic growth, the improvement of that technology was due to the enhancement of precision and control technology of various mechanical components, including gears. Particularly, small gears used in measuring instruments and medical devices that require high precision, as well as small motors utilized in various fields, have seen a dramatic improvement in precision and performance, thanks to the manufacturing technology of micron hob cutters, which is a flagship product of Izawa Technical Research Institute. To be a company that is needed in the global market moving forward, we will sincerely respond to each customer and approach product provision with gratitude for each product. We will also continue to aim to be a company that can contribute to global manufacturing together with our customers, actively engaging in product development.
