Solutions for cost-effective, high-quality machining of titanium blisks

Blisks located on the cold compressor side of the engine are made of titanium, while the hot turbine side requires blisks made of heat resistant super alloys (HRSA).
Key factors to success are:
- Five-axes machine with good simultaneous dynamics
- Turbo five-axes CAM software
- Optimized tools and process knowledge for HRSA and titanium
Tooling solutions for aerospace blisks in titanium
CoroMill® Plura solid end mills for high feed side milling
High feed side milling is an effective method for machining challenging materials. Small radial engagement allows for increased cutting speed, feed and cutting depth due to decreased heat, chip thickness and radial forces. CoroMill® Plura HFS for titanium is a unique solution developed for demanding conditions where chip evacuation and temperature control on the cutting zone are critical. It features an exclusive cooling booster with patented coolant flow grooves that are designed to improve the temperature dispersion.

CoroMill® 316 exchangeable milling heads for high feed side milling
CoroMill® 316 is first choice for high feed side milling in titanium alloys when good accessibility is required. It has an optimized core for high stiffness at long overhangs and is excellent in intermediate conditions when good surface quality is needed. Combine with Coromant EH modular system for effectively performed machining with overhangs up to 6xD.

Plunge milling of slot with CoroMill® 316 gannet cutter
Machining components with slots and pockets is always challenging. With the CoroMill® 316 gannet cutter available to order off the shelf, manufacturing of small, deep slots and pockets is both time- and cost-efficient. The unique gannet concept is designed exclusively for plunge milling and is ideal when tool diameter is limited and a long overhang is required.

Coromant EH modular system
The Coromant EH modular system helps you to achieve the required reach and accessibility with shanks and modular adaptors. The Coromant EH coupling is based on a self-centering screw thread for secure mounting and maximum strength. The coupling has a physical stop which makes it easy to feel when the head is correctly tightened and helps to not overstress the clamping.

Engineered milling concept M5C331
Engineered milling concept M5C331 is a reliable solution for rough slotting of titanium blisks, based on the CoroMill® 331 design. Providing exceptional metal removal rates during these challenging roughing operations, M5C331 ensures cost-efficiency.
