OKK started its career in 1915 with the production of household pumps. It started manufacturing its machine tools in 1934, and today its horizontal and vertical machines are known worldwide.
Nidec Corporation acquired OKK in 2022, raising their presence in the CNC machining industry to the next level.

It includes, among other things, all the spindles, the mechanical drives, its own square precision slide guides, and special control functions.
