Start with blade geometry and interface requirements
An impeller part combines blade surfaces with a hub and interfaces that connect to the assembly. Provide the current CAD model and drawing and identify the controlled blade profiles, bore, fits, datums and surface requirements. The actual route depends on geometry and tool access.
For the service scope, see 5-axis CNC milling. Our 5-axis impeller machining guide covers technical planning; this page focuses on the information needed for a part-specific quote.
Separate machining acceptance from performance tests
- Specify material, quantity and drawing revision.
- Mark blade profiles, hub features and mating datums.
- State surface requirements and the inspection stage.
- List any balance or performance test criteria separately.
- Identify workholding restrictions or areas that cannot be clamped.
A 5-axis label does not guarantee one setup, a specific tolerance or operating performance. We review the actual part and confirm the proposed scope before quotation.
Request an impeller machining review
Send the model, drawing, material, quantity and critical acceptance criteria. Identify which surfaces or interfaces must be measured and what records are needed for release.
