Solutions for cost effective and high-quality machining of aerospace impellor 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 here 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 – tool is programmed with a roll entry and exit from cut:

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

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

Finishing the blade profile

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

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