Five-Axis Impeller CNC Machining: Achieving Ultimate Precision and Efficiency
In the world of high-speed rotation, every impeller determines the limits of efficiency and performance.
From aircraft engines and turbochargers to high-end fluid equipment, the precision, balance, and surface finish of impellers are core competitive advantages.
However, traditional three-axis machining often struggles to balance complex surfaces, tool interference, and high-precision requirements.
This is precisely where five-axis CNC machining comes in.
Why choose five-axis impeller machining?
Complex curved surfaces formed in one go
Five-axis machining enables multi-angle tool cutting, eliminating multiple setup errors and ensuring a smooth, seamless blade root and transition surface.
Highest machining accuracy
The equipment is equipped with a high-resolution rotary axis and precision spindle system, and combined with intelligent toolpath programming (UG/PowerMILL), it achieves ±0.005mm accuracy.
Efficiency and consistency
Automated fixtures and a multi-station tool changer ensure stable and consistent dimensions within the same batch of impellers, significantly reducing lead times.
High-quality surface finish and post-processing
Thanks to optimized toolpaths and a cooling system, the blade surface roughness can reach Ra0.4–0.8, allowing for direct assembly without the need for additional polishing.
