6061 Aluminum Alloy Centrifugal Impeller

Low-volume production places higher demands on consistency and delivery efficiency. Backed by high-precision equipment and a stable production system, KT maintains reliable output even in small batches—ensuring each part meets consistent dimensional accuracy and quality standards. By minimizing batch variation and uncertainty, we help reduce trial risks and keep projects moving forward efficiently.

When handling high-mix, low-volume demands, KT remains responsive while maintaining delivery pace, without compromising quality or lead time.

Detailed Description

This centrifugal impeller is the core working part of centrifugal fluid machinery. Integrally milled from solid aerospace-grade aluminum alloy bar via 5-axis linkage CNC, the blade passage adopts high-efficiency aerodynamic design with twisted profiles smoothly transitioned by high-precision CNC machining to reduce airflow loss and eddy currents. The central hub and shaft hole are integrally formed with high coaxiality, enabling high-precision interference or key connection with the spindle. Under high-speed rotation, it converts mechanical energy into fluid pressure energy to achieve efficient pressurization. Lightweight, high-strength and corrosion-resistant aluminum alloy material can operate stably under high-speed and high-temperature conditions, widely used in power equipment in aerospace, automotive, energy and other fields.

Manufacturing Process

1. 5-axis linkage CNC precision milling, forming blade passages, hub and shaft hole in one pass
2. High-speed milling optimization to ensure smoothness and contour accuracy of blade profiles
3. Precision dynamic balance correction to eliminate vibration and unbalance during high-speed rotation
4. Surface polishing/sandblasting treatment to reduce passage roughness and fluid resistance
5. Optional anodizing, hard anodizing, spraying anti-corrosion and wear-resistant surface treatment

Overall process: 5-axis Linkage CNC Precision Milling Machining, complex curved surface impeller parts processing, focusing on high-precision integrated forming of high-efficiency passages and twisted blades.
