Complex 316SS pump impellers machined on 5-axis with CMM verification and dynamic balancing for a US customer.
(Content in this language is being translated. Showing English version.)
A US water-treatment company required stainless steel impellers with complex curved vanes for a pump upgrade program. 5-axis machining was essential.
Project Requirements
316 stainless steel, 12 vanes, dynamic balance G6.3, Ra 1.6 on hydraulic surfaces, 200 units first order.
Machining Strategy
Roughing on 4-axis mill-turn, hydraulic surfaces finished on simultaneous 5-axis with 5-flute bull-nose tools, followed by passivation and dynamic balancing.
Quality Verification
Every impeller was CMM-scanned against the 3D model and dynamically balanced. Full inspection reports were delivered with each shipment.
