Carburizing hardening and polishing processing using steel materials! Capable of buff polishing with excellent surface roughness.
At Nakamura Manufacturing, we perform "carburizing hardening and grinding processing" using SCM415 material. In addition to high-precision grinding after carburizing hardening, buff polishing with a surface roughness of 0.8S is also possible. We can also accommodate groove grinding processing for O-ring grooves, which are prone to runout. 【Features】 ■ Carburizing hardening ■ High-precision grinding processing ■ Buff polishing finish with a surface roughness of 0.8S ■ Groove grinding processing for O-ring grooves *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.
