New Products for Titanium Machining

The picture shows the landing gear of an aircraft.

The low thermal conductivity of titanium, together with its high tensile strength, means that the tools are subjected to high thermal and mechanical stresses. The new MAPAL titanium range features sophisticated heat dissipation and heat-resistant coatings. As a result, comparatively high cutting values can be achieved with high process reliability at the same time. Compared to conventional solutions on the market, 25 to 35 percent longer tool lives are achieved.

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 finishing up to a working depth of 2xD. 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 4 to 25 mm. Special dimensions are possible.

MEGA-Speed-Drill-Titan

MEGA-Speed-Drill-Titan

Cost-efficient and productive

The high-speed drill MEGA-Speed-Drill-Titan is characterized by cost efficiency with maximum productivity. The double edge solid carbide drill is equipped with four guiding chamfers for optimum roundness. To bring the maximum coolant flow to the main cutting edge, the coolant is directed backwards along the shell surface. In this way, the guiding chamfers experience maximum cooling, dissipating the generated heat effectively. A new design of the chip flute produces small chips. The convex main cutting edge ensures high stability and long tool life. The drill is available from diameter 3 to 20 mm in length 5xD.

Typical parts that can be created with the drill, which achieves a cutting speed of up to 40 m/min, are structural parts in the aerospace industry, for example, brackets for the wing box or the landing gear with its numerous bores.
