What is CNC machining of impeller profiles (5-axis)?

CNC machining of impeller profiles (5-axis) capability for titanium components

Precision machining capability for CNC machining of impeller profiles (5-axis), utilizing multi-axis CNC centers with in-process inspection and SPC quality control.

Engineering Parameters & Capabilities

Simultaneous 5-axis CNC milling enables complex freeform geometries to be machined in a single setup, eliminating positional errors from multiple fixtures. The rotary A and C axes provide full access to undercut features and compound-angle surfaces while maintaining optimal tool engagement angles for titanium, specifically for impeller. Precision impeller for Aerospace, Industrial present unique challenges: Closed impeller channels with depth ratios > 5:1 create chip evacuation difficulties. Split toolpaths with 3 mm ballnose cutters at 0.1 mm stepover required for surface finish.

Parameter	Primary Method	Alternative Method
Axes Simultaneous	5 axes (X/Y/Z + A/C rotary)	3+2 axes (positional)
Best For	Blisk, impeller, turbine blade, complex bracket	Prismatic mill-turn parts
Surface Finish (Ti)	Ra 0.4 µm with small-step finishing	Ra 1.6–3.2 µm
Cycle Time	30–70% faster than 3+2 for complex surfaces	Faster for simple prismatic features
