Machining the turbine casing

1. MaxiMill 270-19 – face milling cutter

Roughing operations with large depths of cut

  • Very soft-cutting system due to positive axial angle
  • Cutting depths of up to 10 mm can be achieved
  • Solid SDKT 1907 indexable insert
  • High process security
  • High chip volume

2. Special boring bar – special solution adapted to the customer's application

Rear countersinking

  • Rear countersinking easily possible for interrupted cuts
  • Through hole production and countersinking in one setup

3. Special side and face milling cutter with tangential- and round indexable inserts

Slot milling

  • Customised solutions up to a diameter of 600 mm
  • Solid tangential inserts for maximum process security
  • Alternative side and face milling cutter with RPNX 20 button inserts

4. KUB V464 indexable insert drill with ABS T connection

Producing screw holes

  • Modular drilling system
  • Hole range Ø 80 – Ø 160 mm
  • The drill bit can be set +5 mm in Ø
  • Configurable hole depth

Application example: face milling (1)

Component: turbine casing
Material: GX12CrMoVNbN9-1

Application data

  • Tool:  A270.200.R.11-19
  • Indexable insert:  SDKT 1907AESN-R50 CTPP235
  • Vc = 125 (m/min)
  • ap = 3 - 10 (mm)
  • fz = 0.25 (mm)

Machining is gentle on the spindle due to the very soft cut!

Application example: slot milling (3)
