Made in Japan machine tools are regarded throughout the world as synonymous with high quality.
Okuma has been Japan's No. 1 in sales since the company was founded in 1898.
Okuma continues to be supported as a top brand in Japan
because we continue to refine our product quality backed by advanced technology.
Careful selection of high-quality castings and the creation of a strong internal structure that requires significant time for forging leads to high load resistance.
Diagonal rib structure
Cumulative shipments: 50,000 units
Applicable Okuma products: 120 models
Machine design and highly accurate thermo deformation control technology that responds to temperature changes caused by machining, etc. in a straightforward manner.
Achieving highly accurate machining over long runs regardless of changes in ambient temperature.
Collision Avoidance System
Real-time simulation using 3D data of machine structures.
Prevents collisions and drastically reduces cycle time.
lnterference check precedes actual movement
Detects and suppresses chatter vibration during machining and calculates optimal machining.
Providing machining technologies that supports high accuracy and productivity which anyone can use.
Offering machining solutions only possible through the use of a CNC developed by Okuma.
Based on actual shop conditions, evaluations with continuous 2,000-hour long durability tests at maximum spindle speed are performed to also assure extended product life. Only successfully tested machines are approved for sale as Okuma products.

The processing and assembly of each main spindle, said to serve as the "heart" of every machine, are performed in a room which is kept at a constant temperature.
Since the temperature is kept at 23°C with an allowable variance of ±1°C and there is no temperature change between processing and assembly, dimensional accuracy is stabilized, making high-precision processing and assembly possible in a short amount of time.
In addition, since the air pressure in the spindle unit assembly area is increased, high quality is maintained by preventing the intrusion of dust.
* A round bar with a diameter of 100 mm expands by approximately 1 micrometer (0.001 mm) for each degree (°C) the temperature rises.
After years of hard training, the skills of master craftsmen continue to be passed on.
Japanese style hand/hip scraping "Kisage" results in beautifully finished flat and curved surfaces achieving high accuracies of 1 and 2 µm that exceed automated scraping systems, and the mated scraped surfaces prevent machined workpiece deformation while supporting their accuracy requirements.
For moving components, oil film applications reduce slide resistance, and produce delicate, beautiful patterns reminiscent of traditional Japanese designs appearing on the entire finished surface.
Outstanding craftsmanship is poured into each Okuma product, leading to highly accurate components, assemblies, and the best finished machine tool possible.
Okuma started manufacturing and selling noodle machines in 1898.
Possessing an enormous passion for improving quality, our founder Eiichi Okuma had at the time developed a revolutionary high-precision lathe in-house required for making 0.05 mm wide parts for the purpose of improving the main parts of the company's noodle machines.
This technology would become the basis for entering the machine tool field, transforming Okuma into an integrated machine tool manufacturer.
In 1963, Okuma developed the OSP, an NC controller with absolute position feedback.
By developing both the NC machine and controller, Okuma was able to bring products that accurately supported user needs to the market.
As a manufacturing professional, we always listen to customer feedback
and take on the challenge of creating new value through innovation and by providing
a level of comprehensive support that exceeds expectations.
Okuma strives to become a company that lives up to customer expectations and inspires them.
We open the future possibilities of manufacturing.
As a leading machine tool company, learn more from the Okuma brochures which describe our wide range of products, from highly accurate and rigid CNC lathes, machining centers, and multitasking machines to the Okuma CNC controls (OSP).
