Achieving high machining precision with one chucking! Grinding technology that processes both inner and outer diameters simultaneously.
At Nakamura Manufacturing, we perform "inner diameter and outer diameter taper machining" using a vertical grinding machine with one chucking. High-precision grinding is possible as we can process the inner and outer diameters simultaneously. We accommodate sizes of φ300×550L. 【Features】 ■ Simultaneous grinding of inner and outer diameters ■ Excellent coaxiality and concentricity ■ High precision of less than 0.003 *For more details, please refer to the PDF document or feel free to contact us.

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.
