Precision 5-Axis CNC Impellers

Detailed Description

Our precision 5-axis CNC impellers are manufactured for rotating equipment where blade profile, flow-channel geometry and hub accuracy directly influence mechanical and fluid performance.

Simultaneous 5-axis machining allows the cutting tool to continuously follow twisted blade surfaces while accessing narrow passages between adjacent blades. Controlled tool orientation also helps reduce interference and maintain consistent machining conditions across the complete blade profile.

Open and semi-open impellers can be manufactured directly from customer CAD models for prototype development and low-volume production.

Available Surface Finishes

• Precision Machined Finish: Maintains controlled cutter paths across blade and hub surfaces.
• Polishing: Reduces surface roughness on flow-contact areas.
• Anodizing: Available for aluminum impellers requiring corrosion protection.
• Passivation: Improves corrosion resistance of stainless steel impellers.

Structural & Functional Breakdown

• Twisted Blade Structure: Three-dimensional blades provide controlled flow geometry.
• Central Hub Structure: Precision bore or mounting features connect the impeller to the shaft.
• Inter-blade Flow Channel: Narrow channels between blades require controlled multi-axis cutter access.
• Integrated Shroud or Rim Features: Can be machined according to specific impeller designs.

Key Features

• Continuous Blade Surface Machining: Simultaneous axis movement follows complex blade profiles.
• Tool Collision Control: Multi-axis orientation improves access between closely spaced blades.
• Smooth Flow-path Finishing: Optimized finishing paths reduce unnecessary surface transitions.
• Precision Hub Machining: Controls the relationship between the blade geometry and rotational center.

Applications

• Pump Impellers
• Turbochargers
