Solutions for cost effective and high-quality machining of aerospace fan casing
The machinability of titanium is low, however, unlike the nickel alloys, ceramic cannot be applied. This puts challenges on productively removing material. Keeping the cutting temperature low is the key to success. The key factors together, with optimized programming, are choice of insert shape and utilisation of high-pressure coolant (HPC).
Tooling solutions for aerospace fan casings
CoroTurn® SL70 – the flexible modular tooling system
Round inserts offer best accessibility and productivity due to reduced entry angle and chip thickness. The programme consists of round carbide inserts as well as the stable CoroCut grooving system and comes with HPC as standard.
- Radial and axial clearance requirements covered in compact program
- Oval coupling offers excellent stability and accessibility
- Coromant Capto size C6 for multi-task and VTL requirements
CoroTurn® HP - Advanced cooling technology
The CoroTurn® HP programme consists of a full range of tool holders with advanced cooling technology. The fixed nozzles in the tool holder promise improved chip control, process security and high productivity, due to jets perfectly directed at the cutting zone. In combination with dedicated insert geometries for high pressure coolant, the performance in terms of tool life can be increased.
VTLs by design need to have either manual quick change or automatic tool change. With the coolant piped through the ram directly to the spindle there are no coolant pressure restrictions - as is the case with turret lathes and rotating spindles.
Coromant Capto Jetbreak, developed for UHPC applications in VTLs, has been applied for many years, predominantly in titanium casing, disc and spool applications. Much of the design and application knowledge developed in this field lay behind the now standard CoroTurn HP program for HPC.
Xcel in titanium
A radical tooling solution for semi-rough turning into shoulders. Xcel combines the advantages from square 45 degree lead approach angle and rhomboid 90 degree lead angle tools.
- Rhomboid - accessibility into confined spaces and machine in two directions with easy tool offset
- Square – high feed rate and long tool life
- Xcel reduces the lead angle and chip thickness allowing an increase in feed and speed
- Double the metal removal rate and at the same time double the tool life!
CoroMill® Plura HFS - solid carbide end mill for high feed side milling
Utilize the new CoroMill® Plura HFS families for reliable and productive milling. The optimized grade for nickel based alloys have sharp, controlled cutting edges, providing long and predictable tool life along with high metal removal rate.
CoroMill® Plura - 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.
CoroMill® Plura is a range of high quality solid carbide end mills that offer productive, efficient, and perfectly reliable milling solutions.

CoroMill® 300 - Light cutting face and profile milling cutters
Helical ramping of larger diameter holes with CoroMill® 300 provides the most secure and productive method here. The cutting forces are much lower than drilling, which also struggles with the interrupted exit into the bore.
For rough milling around a boss, use CoroMill® 300 with a roll in programme combined with round inserts to reduce notch wear and allow high feed rates.
