The highlight of the last customer event on the topic of titanium was, without doubt, the double-spindle BTP 5000/2 profiler – already the third machine of this type, which was built on behalf of a British aircraft manufacturer. They gave their permission to show this 240 ton Big Titanium Profiler to interested parties. The BTP series was developed for the high-quality machining of particularly long and complex titanium components. Accordingly, the machine beds, guides and spindles ensure optimal stiffness and damping. The double-spindle BTP 5000/2 is almost twice as productive as the single-spindle variant that is also offered. This is because it enables two titanium structural components, up to five metres long, to be machined simultaneously.  The machine has a vertical pallet of4,5 m × 1,8 m and two 37 kW geared spindles with a maximum torque of 940 Nm to 1,300 Nm and a maximum speed of 5,600 rpm or 8,000 rpm. Reinhard Fitz, Sales Consultant for the Starrag Group explains: “With an insert mill, we can demonstrate massive cuts on such a BTP, with a volume of up to 760 cm3  per minute in TiAl6V4, with no unstable conditions arising. However, these are not values for a production facility where the profitability analysis would not warrant it. This is because the tool wear is enormous with high cutting parameters.”
