Titanium machining

In the aerospace industry, materials that are both high-strength and lightweight is the key. By making use of new combinations of materials, weight can be reduced further, strength and corrosion resistance can be increased and assembly can be simplified by using an integrated design. Whereas structural parts made of aluminium, titanium or high strength steel are machined on machining centres or gantry machines, final assembly machining is carried out by handheld machines, drill feed units or robots.
