Valve body parts adopt the whole block material CNC precision machining process. Through multi-surface machining, precision boring and thread control, they achieve the integration of complex hole systems and high-reliability fluid channels, meeting the strict requirements for performance and consistency in hydraulic, construction machinery, new energy, and aerospace systems. CNC Machining Process Flow for Valve Bodies / Manifold Blocks:
Raw Material Preparation: Common materials 6061-T6 / 7075/304 / 316L / 17-4PH. And through these ways to control raw material quality: Material Certificate (MTC),Furnace Number / Batch Identification,Preliminary inspection of appearance and dimensions.
Process Planning & Datum Definition: Analyze Functional holes (spool holes, main channels)/sealing surface/Threaded interface in the drawings. And confirm Primary datum plane/Key hole system datum.Formulate the processing sequence, clamping scheme and inspection point setup for precision components.…
