Blisk
Blisks are becoming more common in the high-pressure compressor area of the engine due to the advantages of weight, efficiency and servicing.
Key factors to success are:
- 5 axes machine with good simultaneous dynamics
- Turbo 5 axes CAM software
- Optimized tools and process knowledge for titanium/HRSA

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 bull 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 programmedwith a roll entry and exit from cut: | |
- controlling the arc of engagement
- low cutting forces allowing high depths of cut
Plura 50 degree relieved shank, bull 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.
