Ring Flange Component With Machined Flange and Circular Ring Profile, Central Circular Bore

Pump housings, hydraulic manifold connections, and bearing block mounting faces all use a machined flange where central bore concentricity and face flatness together determine whether the mating assembly seats without runout at the bolted interface. Ningbo Zhenhai Weiye Machinery (Ningbo, Zhejiang) turns this ring profile machined flange with circular central bore using their 40 CNC lathes, 6 turning-milling composite machines, and external cylindrical grinders, with central bore diameter, flange face flatness, and OD concentricity maintained to your drawing limits. ISO 9001 certification at Weiye's Ningbo facility (some 2,000 m²) governs dimensional inspection for aerospace, automotive, hydraulic, and medical equipment flange applications. Swiss machining and gear forming extend capability for complex profile flanges. Clients span military, automation, and oil & gas sectors. Bore diameter, face flatness, and material grade.
