Multi-Axis CNC Machining of PEEK Turbo Rotor for Honeywell
Project Background: Lightweight High-Performance Turbo Rotors
Honeywell required a high-speed, chemically resistant, and lightweight turbo rotor component for use in precision airflow control systems. The material needed to maintain dimensional stability under thermal cycling and high rotational velocity. Neway was selected to deliver complete CNC machining of this component using PEEK (Polyether Ether Ketone), a high-performance thermoplastic widely adopted in aerospace and industrial sectors.
Why PEEK Was Chosen for Turbo Rotor Applications
PEEK offers outstanding thermal stability, wear resistance, and chemical durability—making it ideal for advanced rotor applications.
Property | Value |
|---|---|
Continuous Use Temperature | Up to 260°C |

PEEK maintains its mechanical integrity and dimensional stability even under combined chemical and thermal stress. Learn more about PEEK CNC Machining.
CNC Machining Process Overview
CNC Turning for Rotor Profile
Initial profiling and central shaft feature formation were performed using CNC turning. PEEK was turned at low RPM to prevent material softening, with sharp carbide inserts used to maintain surface quality.
Multi-Axis CNC Finishing
To achieve precision on curved vane features and concentric balance, multi-axis CNC machining was applied. This enabled undercut detailing and pitch control in a single setup, maintaining balance tolerances within ±0.01 mm.
Quality Control and Testing
Dimensional Accuracy: All shaft and vane features were measured with a high-resolution CMM
Balance Testing: Dynamic balancing validated rotor concentricity for high-speed operation
Surface Finish: Rotor surfaces achieved Ra ≤ 0.8 μm, critical for airflow efficiency and vibration suppression
Project Outcome
Neway delivered a batch of 1,200 turbo rotors for Honeywell’s aerospace-grade airflow management system. All parts passed centrifugal stress testing, thermal cycling, and vibration validation. Honeywell reported increased rotor performance due to superior concentricity and consistent dimensional quality.
