Leading manufacturers around the world rely on Koyo grinding machine tools and apparatus for high-tolerance precision grinding. Using high-quality materials and tooling, we custom engineer our grinders to meet your mass production specifications. Each machine goes through a series of approvals, tolerance checks, and cycle checks before it reaches your floor, ensuring solid machine performance when we set it up and test it in your facility.

Koyo Machinery provides local sales and service support that operates directly from our U.S. Headquarters in Plymouth, Michigan. We offer expert consultations for improving your engineering and grinding process for mass production of quality parts.
