Walter applies Engineering Kompetenz to titanium machining

Tooling giant Walter has launched a new and innovative series of milling tools specifically aimed at the machining of titanium. The new tools are a result of the company's Engineering Kompetenz strategy that involves ongoing development work and partnerships with aerospace OEMs and their suppliers, as well as with CAM specialists and machine builders.

The new Walter M3255 tangential porcupine cutter, and Walter Prototyp Ti40, Ti45 and Ti50 cutters - for rapid material removal and for semi-finishing and finishing, respectively – offer “economical yet the most efficient and profitable solutions” for every company involved in the machining of titanium.

Available in diameters of 50 mm to 80 mm as standard, the M3255 tangential porcupine cutter can also be supplied at any 'odd' diameter between these limits, while the Ti40 is available from 12 mm to 25 mm diameter; the Ti45 from 16 mm to 25 mm; and the Ti50 from 9.5 mm to 25.4 mm.

All are complemented by the Walter ConeFit modular toolholding technology for ease of set-up as well as providing maximum stability for semi-finishing/finishing operations.

With rapid metal removal, high edge life and product security as by-words – and ideally suited to applications such as wing or fuselage assemblies - the M3255 cutter is based on a high-strength, rigid core and monobloc design as well as an optimised flute design for rapid metal removal via a 27deg helix.

With adjustable radial coolant outlets, the cutter will shoulder mill with maximum efficiency and is adept at slotting, too. The cutter features Walter's latest Tiger.tec Silver inserts of WSP45S grade, and each insert has four cutting edges.

Following a similar philosophy, Walter has applied concentric tool path strategies to its Prototyp Ti cutters, where the dynamic tool path cutting width is always controlled via CAM. The result is effective metal removal with consistent finished size and surface quality using tools with asymmetric helix design and micro geometry (which assures controlled cutting pressure and avoids deflection).

The tool is always running in an optimised data condition and therefore avoids chatter, edge rubbing and damaging vibration, while also offering controlled wear rate.

The Ti tools – which are optimised for thin wall deep pocket finishing - are available with 'anti' pull-out shanks to suit a variety of matching spindle adaptors. The tools are ground with a back radius to create soft blend lines and a long cutting edge that achieves a flat wall surface.

ConeFit avoids the unnecessary investment in long, solid carbide tools by being an interchangeable head (face and taper) modular locking interface system. It combines a VHM changeable milling head with a steel tool shank. VHM tool shanks and monoblock spindle adaptors with HSK63, SK40 or Capto C5 and C6 are also available.

Blended tool paths are assured by the use of the ConeFit technology, which also allows constant step finish climb milling to minimise deflection in deep pocket wall finishing.
