In addition to the usual challenges faced by any manufacturing operation, those in aerospace face stronger constraints on weight, strength, and above all, safety. To meet the increasing need for complex monolithic parts manufacturing in the aerospace industry, MAG Cincinnati offers a line of vertical and horizontal profilers in single or multispindle five-axis models. The aerospace industry has an ever-increasing demand for titanium and other hard-metal-alloy components. SNK America has addressed this need with two five-axis profilers designed to efficiently machine hard metals. Titanium is taking over from aluminum in many aerospace applications, and that presents some added challenges to cutting-tool manufacturers. In one instance, Seco Tools Inc provided an answer with its Jetstream tooling. The Jetstream tooling design solved the problem, by delivering a stream of high-pressure coolant directly to the workpiece interface. One benefit of titanium is its weldability, which is now being researched.
