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

The impeller is found in the APU. The machining of the turbo foils is a similar process for both impellers and blisks.

Key factors for success are:

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

Tooling solutions for aerospace impellers in titanium and HRSA

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.

Roughing slot – Titanium

The best method is point milling. Because we are full-slot milling, the axial depth of cut is limited to half the diameter of the tool. The CoroMill® 316 ball nose exchangeable insert offers a great balance of productivity and economy.

Roughing slot – Inconel

Applying trochoidal milling with high-speed machining techniques is the best method. Trochoidal milling—2D roughing/high material removal method using HSM techniques in a confined space or slot. The tool is programmed with a roll entry and exit from cut:

  • controlling the arc of engagement
  • lowering cutting forces and allowing high depths of cut

CoroMill® Plura 50-degree relieved shank, ball nose design, is optimized for axial depths of cut twice the diameter, and low radial cuts.

Semi-finishing and finishing the blade profile

Flank milling (high axial depth of cut) is the fastest method when the component, CAM software and the tool allow.

CoroMill® Plura conical ball nose is optimized for this operation. The tapered design and ball nose feature combine to reach the toughest spots with unmatched accuracy and high quality.

Drill with CoroDrill® 846

The latest development in solid carbide drill technology with geometry optimized for HRSA offers a high number of drilled holes with security and low axial cutting forces.
Secure drilling for thin-walled components

Finish bore with CoroMill® Plura end mill

Circular interpolation is a fast and secure method; one tool can finish a wide range of hole diameters, reducing tool inventory.
