Two centerless grinders were created in a small factory in Yamagata City in 1959. Since then, the centerless grinder, which has continued to evolve and is equipped with groundbreaking technology, is used in various industries such as automotive, electronic information equipment, home appliances, construction machinery, bearings, and medical equipment. We have contributed greatly to the advanced development of today’s industry and society by providing parts processing systems for core products. In addition, since 2000, we have added internal grinders to our lineup and provide ultra-precision drilling systems to manufacturers that process parts for fuel injection devices. We have delivered more than 7,500 of these grinders to companies in more than 30 countries and regions around the world, and our customers are highly appraised and satisfied with our products and services. Thanks to you, our domestic share of centerless grinders exceeds 40%, and our global share exceeds 10%. As a centerless and internal grinder manufacturer that supports manufacturing around the world, we will strive to achieve the world’s highest level of grinding skills and technology, so our grinding technology and grinding machines can contribute to our customers’ profitability.
