Solutions for cost-effective, high-quality machining of HRSA 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 HRSA materials
Engineered milling concept M5C331
Engineered milling concept M5C331 is the economical solution when it comes to rough slot milling of HRSA blisks, offering a metal removal rate that is outperforming the existing solid round tools solutions up to four times.
M5C331 is a proven concept, based on the CoroMill® 331 design and ready to be used with selected CoroMill® 331 inserts from the standard assortment.
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 with grade GC1710 specially developed for nickel-based HRSA materials and a core dimension optimized for high stiffness is first choice for high feed side milling of blisks.

ISO S ceramic ball nose end mill
The ISO S ceramic ball nose end mill is the only ceramic ball-nose end mill on the market for high speed HRSA profiling with small diameters. The brazed ceramic on carbide interface provides both strength and flexibility, and the ball nose geometry ensures an easier, faster profiling.
Roughing of slots with plunge milling
Tool: Engineered solid carbide plunge cutter with Gannet® geometry
Method: Rough opening between blades with plunge milling
Machining components with slots and pockets is always challenging. Applying a plunge milling strategy can make manufacturing of small, deep slots and pockets more 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.
Semi-finishing and finishing of the blade
Experience our extensive offer of profiling end mills optimized for blisk machining. The tools are ideal for intricate shaping and fine-tuning of the blade’s surfaces, ensuring a high-quality finish.
First choice for all point milling operations, with high flexibility in tilt angle and reach.
For challenging point milling operations with undercuts and complex shape deburring.
CoroMill® Plura conical ball nose
For flank milling or point milling operations where accessibility is challenging.
For high productivity surfacing needs. The optimal solution for productivity gains and cycle-time reductions.
Highly secure drilling with CoroDrill® 860
CoroDrill® 860 with -SD geometry is a short-hole drilling solution optimized for machining nickel-based ISO S materials. This drill offers consistent and predictable tool life with high dimensional accuracy and excellent hole quality.
CB7014 high speed CBN turning solution for nickel-based alloys
Finish turning of aerospace components are challenging operations performed in demanding ISO S materials. Using CBN inserts allows for increased cutting speed and improved productivity while maintaining good surface integrity on the component. CBN inserts optimized for high speed finishing of nickel-based heat resistant super alloys are now available as a stocked standard solution.
CoroTurn® 107 with rail interface for profiling and pocketing in HRSA materials
For finishing in HRSA components with relatively open features it is optimized to use the positive, screw-mounted CBN insert. With up to 12 insert indexes it will boost your productivity in HRSA materials. The rail interface ensures mounting security, offers process security and increases reliability and tool life for your profiling and pocketing operations.
