The company began to manufacture machine tools.

Eiichi Okuma obtained his first patent for a machine tool with the "Okuma automatic gear cutting lathe" (patent no. 25829).

The company name was changed to Okuma Machinery Works Ltd.

Sales of OS center lathes started. With a tremendous market response, it became a best-selling and long-selling lathe with a total of 2,000 units shipped over 25 years.

Okuma became No. 1 in domestic production of machine tools.

Manufacture of DRA radial drilling machines started. Okuma became the No.1 producer (volume) of radial drilling machines in Japan.

Manufacture of DRA-J drilling and boring machines started. Together with the DRA, the Okuma name became synonymous with industrial drilling machines.

Manufacture of LS high-speed engine lathes started. A total of 30,000 units of this small, "Type LS Productive" lathe were sold. With sales in 40 countries, it became Okuma's biggest hit product.

Research started on the OSP numerical control (NC) toward replacing mechanical movements with digital control.

The OSP III NC with absolute position feedback was developed. Okuma embarked on a history as Your Source for Machine & Control.

Manufacture of the MDB double column machine started. For milling, drilling, and boring applications on a single machine, two types (NC or manual) were offered.

Manufacture of the LA40-N NC lathe started. Okuma's first mass produced NC lathe. It was a highly rigid machine that used a slanted bed to achieve high accuracies more easily.

Manufacture of MCD double column machining centers started—Okuma's first double-column machining center.

An assembly factory was completed at the current world headquarters plant in Oguchi (central Japan). This completed Okuma's manufacturing and sales management system for NC lathes.

The NC Center was opened with demonstraction and educational facilities for NC machines in north Nagoya, which at the time served as company headquarters.

Okuma's OSP 2000 CNC (computerized NC), which led the world as a practical CNC with a built-in computer, was completed. Okuma's first CNC was mounted on the LA45-N, other lathes, and the MDB-N boring machine. Production continued for more than 7 years and it became a best seller.


The OSP 300 CNCs with microprocessors was completed. It played a key role in the development of simultaneous 4-axis CNC lathes and became a driving force in the spread of CNC machine tools.

Manufacture of the MC-5/5H horizontal machining centers started. It was Okuma's entry into the small and medium-sized applications market.

The IGF (Interactive Graphic Function) was launched; a conversational programming tool that allowed users to create part programs by following quick-and-easy interactive user graphics--which also attracted much attention.

Manufacture of the LB15 CNC lathe started; featuring compactness, ease of use, and powerful cutting. It became a hit product, recording sales of more than 15,000 units over the 10 years after its launch.

Company headquarters moved from north Nagoya to Oguchi in 1982. After the move, Okuma's largest in-house trade show, the 1st Okuma Machine Fair, was held.

K1, the first factory at the Kani Plant was completed in Kani City.

One-Touch IGF, an interactive NC with that automatically determines all the machining processes, was developed. The number of input strokes reduced by 60% compared to the previous version. Input time was also greatly reduced.

The company name was changed to Okuma Corporation. At the same time, the corporate logo in use today was launched.

Manufacture of the MCR-BII double-column machining center for 5-sided applications started. Machining of all kinds of parts became possible with a rich array of attachment heads, greatly increasing productivity in the machining of large workpieces.


Toward new value creation

Machining Navi, another Okuma Intelligent Technology was developed; with a cutting-conditions search function that raises productivity.

Dream Site 1 (DS1), a factory for self-contained start-to-finish production, from parts machining to assembly, was completed at the headquarters plant.

"OSP suite," a next-generation intelligent CNC was developed. It comes with "suite apps" for better efficiency in each production process and "suite operation," which enables changes to the operation screens to match individual operator preferences.

The "OPEN POSSIBILITIES" brand message was launched.


The LASER EX Series was developed. These next-generation super multitasking machines, with laser machining technology, are the ultimate machines for process-intensive machining from materials to finished product on a single machine.
