Since its foundation in 1956, under the leadership of the company’s first president, the company has been engaged in the precision machining of large parts for power generation turbines and space aircraft, and materials for large structures such as bridges using our large-scale machining tools. In 1998, in response to changes in the structure of the industry, Toho Koki Seisakusho entered the semi-conductor industry to utilize its existing precision machining technology.

We initially started operations in the semi-conductor sector with the machining of CMP pads for substrate polishing, but have since expanded our operations to include the manufacture of equipment for machining grooves in CMP pads, inspection equipment, and semiconductor substrate polishing and processing equipment.

We will continue to contribute to society with innovative eco-technology, constantly striving to develop cutting-edge technologies to meet the needs of industry.
