This heavy-duty stainless steel flange hub is machined entirely on high-rigidity Okuma turn-mill machine centers, completing all outer contour turning, inner bore threading, flange bolt hole drilling and counterboring, angular end face milling and base anti-rotation notch milling in one single clamping. We completely eliminate the cumulative positioning error caused by secondary re-fixturing between separate CNC lathes and 3-axis milling machines, ensuring full concentricity across all multi-stage stepped profiles, 100% perpendicularity between the flange mounting reference surface and the central rotating axis, and no visible tool step marks across the entire mating sealing surface.
We use certified industrial austenitic stainless steel raw bar stock with full mill test report traceability. 316L material provides exceptional intergranular corrosion resistance, high temperature structural stability, excellent mechanical strength under continuous dynamic load, and fully complies with FDA / 3A food contact requirements and industrial fluid service standards. Our raw material goes through low-stress annealing pre-treatment before precision machining, which completely removes internal residual stress and guarantees zero deformation after final machining, surface polishing and long-term continuous operation under high load working conditions.
All post-processing operations are strictly controlled for industrial sealing performance. Standard mechanical mirror polishing removes all micro tool marks and burrs completely, providing defect-free high-gloss assembly reference surfaces. Complete passivation treatment removes free iron particles on the part surface, maximizing long-term rust and corrosion resistance. Electrolytic polishing further achieves ultra-smooth non-stick, non-contaminant surface characteristics, ideal for food processing, pharmaceutical, sanitary fluid and sanitary industrial equipment applications.
