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).

​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

Together with the optimized geometry for machining titanium, tailored programming and high pressure coolant the results are high metal removal, security in machining and long tool life.

​Vertical Turning Lathes (VTLs), Coromant Capto® and Jetbreak™

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!
