Neue Produkte für die Titanbearbeitung

Die niedrige Wärmeleitfähigkeit von Titan führt zusammen mit dessen hoher Zugfestigkeit zu einer thermisch und mechanisch starken Beanspruchung der Werkzeuge. Das neue MAPAL Werkzeugprogramm für Titan zeichnet sich durch durchdachte Wärmeabfuhr und hitzebeständige Beschichtungen aus. Dadurch können vergleichsweise hohe Schnittwerte prozesssicher realisiert werden. Gegenüber marktüblichen Lösungen erreichen die MAPAL Werkzeuge um 25 bis 35 Prozent höhere Standzeiten.

NeoMill-Titan

NeoMill-Titan

Indexable insert milling cutters with a bite

NeoMill-Titan is the name for a whole family of milling cutters with indexable inserts for titanium machining: Shell end face milling cutters in slip-on and shank versions, as well as shoulder milling cutters are part of the standard portfolio. The topography of the indexable insert has been redesigned from scratch for optimum chip formation and removal. The indexable inserts each have two cutting edges and are available with corner radii from 0.8 mm to 4 mm.

An equally new cutting material concept minimises wear and the formation of built-up on the cutting edges. There are two different substrates to choose from. In addition to a wear-resistant universal grade, a temperature-resistant high-performance grade has been developed with which cutting speeds of up to 70 m/min can be achieved.

The tool body has also been newly developed for the high-tech inserts. With ideally adapted shapes, the chip flutes transport the chips out of the shear zone. The unequal spacing of the inserts provides additional stability and smooth running.

Variably designed coolant outlets make the regulation of the flow rate of each individual insert possible.

Features:

Diameter: 32 – 125 mm
Available as shoulder & shell end face milling cutters
Available radii: 0.8 mm / 2 mm / 3 mm / 4 mm

Advantages:

New insert topography for optimal cutting behaviour
Efficient and variable cooling concept increases tool life
Perfect solution for roughing and medium machining
25 to 35 percent longer tool lifes are achievable

OptiMill-Titan-HPC

OptiMill-Titan-HPC

Versatile roughing and finishing

The OptiMill-Titan-HPC four-edged shoulder milling cutter is a versatile tool. The solid carbide end milling cutter can perform roughing operations and can also be used for a finish cut.

The special cutting edge preparation produces clean surfaces and allows full slot milling up to 1.5xD. The core diameter of this milling cutter rises from the cutting edge to the shank, giving it greater stability. The spacing of the cutting edges as well as the helix of the spirals are unequal to achieve smooth running. The coating, which contains silicon, proves to be highly heat-resistant, counteracts the tendency to adhesion and, together with the polished chip spaces, ensures optimum chip removal. The OptiMill-Titan-HPC is available from diameter 6 to 25 mm. Special dimensions are possible.

MEGA-Speed-Drill-Titan

MEGA-Speed-Drill-Titan

Custo benefício e produtividade

A broca MEGA-Speed-Drill-Titan de alta velocidade se caracteriza pela eficiência do cus-tos com a mais alta produtividade. A broca de metal duro inteiriça de duas facas está equipada com quatro guias para uma ótima circularidade. Para trazer o fluxo máximo de refrigerante para a aresta de corte, o refrigerante é direcionado para trás ao longo da superfície que esta sendo cortada. Desta forma, as guias recebem o máximo de refrigeração e dissipam bem o calor gerado. Um novo formador de cavaco produz cavacos menores. A nova geometria com formato de curva garante maior estabilidade na furação e prolonga a vida da broca. A broca está disponível do diâmetro 3 a 20 mm de comprimento 5xD.

As partes típicas da broca, permitem uma velocidade de corte de até 40 m/min, são partes estruturais na indústria aeroespacial, como por exemplo, suportes para a caixa de asa ou o trem de pouso, com seus inúmeros furos.

Características:

Alta estabilidade térmica graças ao revestimento resistente ao calor
Sofisticada dissipação de calor
Estabilidade elevada
Maior custo benefício através da alta produtividade

Vantagens:

Alta confiabilidade do processo e 30% maior a vida da ferramenta
Baixo tempo de ciclo devido aos altos dados de corte
Eficiente fluxo do refrigerante para evitar atrito e calor na aresta de corte
Evita lascas e arestas postiças
