Rotary machining is the lifeline of pump performance,with its core lying in transforming theoretical profiles into high-precision entities.

The process strictly adheres to the"datum-first,allowance-progressive"principle:After machining datum features(center holes,end faces)on CNC lathes,the blank undergoes bulk hardening for surface wear resistance.Subsequent precision grinding on high-profile cam grinders employs formed wheels tracing theoretical coordinates,critically controlling contour accuracy and surface micro-quality.Optical indexing systems ensure multi-rotor meshing synchronization,while dynamic balancing eliminates rotational instability.

Bonve's proprietary cryogenic grinding effectively prevents tooth-root transition zone burns,preserving material integrity alongside geometric precision.

Pump body machining faces the core challenge of controlling∞-cavity geometry.After rough milling via 5-axis machining centers,vibratory stress relief releases casting residuals.Finishing employs turning-boring techniques to maintain bearing bore coaxiality,with cavity profiles dynamically compensated via contour mills+in-process measurement.Seal end faces undergo double-disc grinding for flatness and finish.Bonve's innovation:single-setup machining of cavities and bearing bores,eradicating datum conversion errors.

Shaft machining focuses on power transmission reliability.Bearing journals achieve ultra-cylindricity through rough grinding,aging,and finish grinding,with artificial aging minimizing deformation risks.Rotor-locating features(keyways)use broaching for symmetry,while cold forming ensures pitch stability.Roller burnishing dramatically enhances journal fatigue strength.

Component synergy control is critical for performance realization:

-Clearance-matching machining applies dimensional chain reverse-calculation,precisely aligning rotor-pump body radial/axial gaps with design preload;

Bonve's manufacturing system empowers parts production through three pillars:

1.Precision evolution path–Multi-stage processes elevate dimensional accuracy by two orders of magnitude;

2.Process error-proofing–Real-time traceability of critical parameters prevents batch defects;

3.Closed-loop verification–Meshing light-gap inspection and full-machine testing provide final validation for every rotor set.
