Turbine blades are subjected to phenomenal thermal stresses and must always deliver peak performance over the entire life of the aircraft engine. Aircraft engineers are using super alloys or titanium alloys and a steady stream of newly developed materials to look for new ways of making turbine blades even tougher. This in turn increases the stresses imposed during machining, as these materials are extremely difficult to cut and efficient manufacturing is essential.
Thanks to our tool systems, which are designed to deliver maximum levels of productivity, machining times are kept within acceptable limits, even during the complex roughing processes used for the rhombus and blade.
High-feed indexable insert milling system for larger cutting depths
Highly efficient finishing due to the patented exchangeable head system
Versatile machining options with button inserts
Extremely productive freeform milling with positive button inserts, machining of large areas of Ni-based alloys
Machining of specific contours on the blade root
