Ready packaged aerospace tooling solutions

The package contains a number of new and existing products designed to offer a complete solution and genuine productivity benefits to a number of typical aerospace engine industry applications. It covers the following components - turbine discs, turbine casings, fan casings, spools, shafts, blisks/impellors, and fan discs. For example, turbine discs, are complex turned parts that generally feature profiled pockets with various difficult clearance requirements. New CoroCut angled inserts from Sandvik Coromant provide a complete and stable grooving solution for turbine disc machining. They offer optimum accessibility and the latest aerospace grade GC1115 for machining typical turbine disc materials such as Inconel 718, Waspaloy and Udimet 720. GC1115 offers increased uptime machining due to a unique PVD coating that maintains sharp edges over a longer time in cut. The modular SL70 tooling system with blades designed to fit typical profiles and pocket features, the exchangeable head CoroMill 316 for scallop milling and CoroCut inserts in grade S05F for high productivity turning complete the Sandvik Coromant package for machining turbine discs. Turbine casings are typically manufactured from Inconel or Waspaloy and present machine shops with a significant number of turn-mill operations to remove large amounts of material. Here, Sandvik Coromant recommends ceramic face milling using RNGN inserts to remove metal from turbine casings up to five times faster – at speeds up to 1000 m/min. For rough milling around boss features, CoroMill 300 is the solution with round inserts to reduce notch wear and allow high feed rates. The same cutter can be used for the secure and productive helical ramping of larger diameter holes. Completing the turbine casing programme from Sandvik Coromant is CoroMill Plura with 50° helix in grade GC1620, which is optimised for the finish profile milling of walls and bores. Fan casings require careful selection of insert shape and the application of high pressure coolant to maximise the productivity of these titanium components. SL70 is a new quick change tooling system that combines with Coromant Capto to provide excellent stability when machining difficult-to-access fan casing parts, particularly when using vertical turning lathes. Different configurations of just a few modular building blocks give this tooling (which incorporates Jetbreak high pressure coolant technology) the right support at the right clearance for various fan casing features. With regard to inserts, Sandvik Coromant’s Xcel range offers a radical and innovative solution for semi-rough turning into casing shoulders. All of Sandvik Coromant’s solutions for aerospace engine machining are detailed in its new 20-page brochure ‘Aerospace Engine Total Component Solutions’, which can be downloaded at www.aero-knowledge.com. Sandvik Coromant will be found in Hall 3, Stand D6 at the Paris Airshow.
