basic information
Since it is a submarine that operates in deep sea, 64 titanium, which is lightweight and can withstand pressure, was chosen. However, due to its large specifications that cannot be cast or produced using lost-wax techniques, it was necessary to machine it from round bars. This processing matched the spirit of Nakamura Manufacturing, which is "We can machine anything except air," and it became a project that utilized the five-axis machining center introduced in April 2015.

Company information
We have NC lathes, vertical machining centers, horizontal machining centers, surface grinders, cylindrical grinders, internal grinders, vertical grinders, and three-dimensional measuring machines in-house, allowing for consistent production from medium-sized round workpieces to large-sized ones (Φ200 to Φ800) using our in-house equipment. We can also handle smaller workpieces ranging from Φ50 to Φ300. We are also considering machining from solid materials for prototype parts, as well as processing difficult materials such as titanium and Stellite. Common inquiries often involve flanges with precision requirements for coaxiality, concentricity, roundness, perpendicularity, and parallelism around 0.005 mm. Items such as stator sleeves used in motors, which require thin walls and lead groove machining, can be finished with high precision using our vertical grinding machines. We can propose ways to reduce the management workload for your ordering personnel, so please feel free to consult with us.
