Specialized Tools for Machining Impellers and Blisks

Impellers and blisks are essential components in aircraft engines and turbines. Their structural characteristics include complex curved surfaces, narrow flow channels, deep overhangs, and thin walls. These components are typically made from difficult-to-machine materials such as precipitation-hardened stainless steel, titanium alloys, and superalloys, which demand cutting tools with superior precision, durability, and efficiency.

In response to the machining challenges posed by these materials and structures, a dedicated series of tools has been developed. These tools are designed to meet the specific requirements of impeller and blisk manufacturing, providing optimal performance for high-precision and efficient machining.

1. Tapered Ball Nose Cycloidal Milling Cutter

• Designed for High-Impact Milling: Engineered for cycloidal milling processes, the tool utilizes an advanced combination of substrate material and coating technology. This ensures a perfect balance between wear resistance and toughness, making it suitable for heavy-duty applications.
• Improved Chip Evacuation: For titanium and superalloy materials, the tool incorporates chip-breaking teeth on both the bottom and peripheral cutting edges. This enhances chip removal, reduces cutting resistance, and ensures smoother machining operations.
• Special Bottom Edge Design: The bottom edge features an "arc-shaped" design that increases chip space while maintaining tool strength. The peripheral chip-breaking teeth are specially configured to avoid interference at the rear, extending tool life and maintaining machining stability.
