The dimensions of modern turbofan engines and their turbo fans are impressive. As are the challenges in machining the ring-shaped fan cases, which form the casing for the largest turbine blades of the entire engine. The highest possible levels of rigidity and uncompromising safety are the number one priority, which is why fan cases are also made from titanium.
Anyone concerned with process security and productivity and with a focus on efficiency and surface quality will no doubt already have out tool portfolio on their radar.
