KOYO Machinery USA, established in 1991, is a wholly owned subsidiary of KOYO Machine Industries Co., Ltd., which was founded in 1961 to develop grinding machines for Koyo's bearing division.

Corporate Strength
KOYO Machine Industries is part of KOYO Seiko Co., Ltd., a $3-billion (1997) producer of ball and roller bearings, steering systems, automotive components, machine tools and factory automation systems. Many of these products require grinding. And continuous improvement of these precision products requires advances in the grinding process. We understand that. That's why at KOYO we are advancing the science of grinding.

Markets Served
Today, KOYO Machinery provides turnkey precision centerless, surface and special grinding solutions to manufacturers of automotive and powertrain components, hand tools, ceramics, medical, aerospace, bearings, compressors/pumps and off-highway/agricultural.

Hundreds of firms rely on KOYO equipment for cost-effective, high-consistency, high-uptime production grinding capability, helping them to reduce piecepart costs. With thousands of its machines installed worldwide, KOYO has installed more than 550 machine tools in North America, including CNC centerless, double-disc, chucking, and shoe-type centerless grinders.

Many of these machine tools include full part automation and automated gauging designed and built by KOYO, providing users with reliable turnkey grinding solutions.

KOYO also produces machine tool and automation components, including precision ballscrews, spindle speed increasers, and precision spindles for machine tool applications.

KOYO grinding process research & development is ongoing at headquarters in Osaka, Japan, where the company also develops grinding processes for its bearing manufacturing division.
