High-Efficiency Cooling Fan Impeller for Industrial Motor Applications
Description
5-Axis CNC Machined Micro High-Speed Cooling Fan Impeller | G2.5 Dynamic Balance, Custom Cooling Component for Micro Servo Motors
As a core cooling part for micro precision power equipment, this 5-axis CNC machined micro high-speed cooling fan impeller is tailor-made for compact, high-speed micro devices. With exceptional precision and stable heat dissipation performance, it stands as the preferred precision component to solve “high-temperature overload and vibration noise” pain points in micro servo motors and micro turbochargers.
1. 5-Axis CNC Simultaneous Machining: Military-Grade Precision Quality
Crafted on DMG/Mazak 5-axis CNC machining centers, we adopt a composite process of “5-axis simultaneous milling + precision turning + high-pressure air deburring” to ensure quality from the source:
- Extreme precision control: ±0.01mm tolerance for blade profiles and ±0.005mm for shaft hole positioning datums, perfectly fitting the narrow installation space of micro devices for seamless integration.
- Premium material options: 6061-T6 aluminum alloy (lightweight + high heat dissipation) as standard; 7075-T6 high-strength aluminum alloy (for high-speed applications) or brass (for special cooling scenarios) available upon request.
- Customizable surface treatments: Anodization (gold/natural color, enhanced corrosion resistance), passivation, sandblasting, etc., balancing heat dissipation efficiency and aesthetic adaptability.
2. G2.5 Dynamic Balance: Stable Operation at Up to 15,000RPM
Engineered for the high-speed operation needs of micro devices, the product achieves three key advantages—”low vibration, high efficiency, and long lifespan”—through structural optimization and rigorous testing:
- High-speed compatibility: Supports continuous operation at ≤15,000RPM, precisely matching the working conditions of micro servo motors and micro turbochargers.
- Strict dynamic balance standard: Complies with G2.5 dynamic balance grade, with blade residual unbalance ≤0.5g·mm, eliminating vibration and noise during high-speed operation.
- Excellent fatigue resistance: 6061-T6 aluminum alloy offers tensile strength ≥290MPa and hardness ≥95HB, combining lightweight design with fatigue resistance to extend overall equipment service life.
3. Core Applications: Micro Servo Motors & Precision Instruments
Widely used in core sectors including automation, power equipment, and precision instruments, with key applications in:
- Built-in cooling modules for micro servo motors in 3C automation lines (e.g., chip mounters, micro robotic arms).
- Auxiliary cooling systems for micro turbochargers in motorcycles and small generators.
- Internal cooling devices for precision instruments such as micro laser markers and laboratory micro chromatographs.
4. Full-Scale Customization & ISO9001 Certification: Adaptable to Multi-Batch Purchases
Leveraging mature CNC machining capacity, we provide flexible customization and end-to-end quality control to meet diverse procurement needs:
- Full-size customization: Blade quantity (8-12 pieces), impeller diameter (φ25mm-φ90mm), shaft hole diameter (φ5mm-φ15mm); full-size machining supported based on customer 3D drawings (STEP/IGS formats).
- Multi-batch delivery: Rapid prototyping for small batches (1-50 pcs), stable delivery for medium batches (50-500 pcs), and cost-effective mold blank + CNC finishing solutions for mass production (500+ pcs).
- Authoritative quality assurance: Complies with ISO9001:2015 standards; free dynamic balance test reports provided; 100% full-size inspection for each batch using coordinate measuring machines (CMM).
