2025    - Towards KURODA’s 100th anniversary -

The large number of technologies and products KURODA has accumulated over its more than 90 years of history cover a variety of fields, ranging from machining to measurement. KURODA believes that its ability to combine various technologies to solve its customers’ issues is one characteristic that puts KURODA in a unique position.
KURODA intends to keep true to its principles even beyond its 100th anniversary, continuing to contribute to the progress of the industrial society at large and the mutual development of customers, shareholders, community, personnel and company, as well as establishing ”Precision by KURODA” as a worldwide brand of quality and trust.

Motion Controls systems business : Aiming at being the compact linear motion system manufacturer with the shortest delivery time

”Motion controls systems” are mechanical elements essential for machines to move accurately.
By leveraging the proven precision technology passed down in the company since its foundation and its global network, KURODA can not only provide various motion control system products including precision ground ball screws, but also offer solutions ranging from design of the motion control system product to manufacturing, sales, and after-sales services.
Hereafter, KURODA, with the aim of becoming a global brand of precision linear motion systems, will further work on its ability to provide solutions to add units and systems to its offering in order to respond to the needs of any industry with proven precision technology.

Press Tool & Die systems business : Aiming at being specialists of high-performance laminated cores

High-performance, silent motors capable of drawing the full potential of a product is a perpetual topic among manufacturers.
The ”FASTEC® system” dies, on which KURODA started working in the 1940s, are dies for ”motor cores”, that is, the heart of the motors. These dies allow for punching to rotation, stacking, measurement, and assembly inside the die, realizing accuracies on the order of microns and dramatic labour-savings in the manufacturing process.
By developing and proposing manufacturing methods that meet the needs of customers and those of the times, KURODA aims to become a global supplier of laminated cores for high-performance electric and electronic motors, as well as for the systems that manufacture them.

Press Tool & Die systems business

Machine Tool & Measurement systems business : Aiming at being a total solution provider of precision measurement and machining

The ”Machine Tool & Measurement systems business”, combining KURODA’s core technologies of ”measurement” and ”grinding” into one, offers total support ranging from measurement to grinding by leveraging its comprehensive expertise.
KURODA will focus in the development of machining technology related to grinding, polishing, and measurement as only KURODA can, such as surface grinding machines which were first developed to manufacture its own dies; manufacturing of jigs for in-house use; and high value added grinding machines developed by combining measurement system with special jigs, in addition to supporting manufacturers all over the world.
