Solutions for cost effective and high-quality machining of aerospace Blisk in titanium

Aerospace Blisk in titanium

Blisks are single engine components where the hub and blades are machined from a solid piece of material. On the cold compressor side of the turbine, Blisks are made of titanium, while the hot, combustion side requires heat resistant super alloys.

Key factors to success are:

  • 5-axes machine with good simultaneous dynamics
  • Turbo 5 axes CAM software
  • Optimized tools and process knowledge for HRSA and titanium

Tooling solutions for aerospace Blisks in titanium

CoroMill® 316 - Plunge roughing of slot

Machining components with slots and pockets is always challenging. With the CoroMill® 316 Gannet plunger geometry available to order off the shelf, manufacturing of small, deep slots and pockets is both time- and cost efficient.

Finishing the blade profile

When the component, tool and CAM software allow, flank milling (high axial depth of cut) is the fastest option to use.

The standard programme of conical ball nose end mills is specifically designed for this operation. They offer excellent stability combined with reach.
