Sandvik Coromant has released its Aerospace Engine Solutions Package, containing new and existing products for typical aerospace engine industry applications.

Sandvik’s Corocut angled inserts provide a complete and stable grooving solution for turbine disc machining.

They offer optimum accessibility and 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 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 turning complete the Sandvik package for machining turbine discs.

Turbine casings are typically manufactured from Inconel or Waspaloy and present machine shops with a 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 1000m/min.

For rough milling around boss features, Coromill 300 has round inserts to reduce notch wear and allow high feed rates.

The same cutter can be used for the secure helical ramping of larger diameter holes.

Completing the turbine casing programme from Sandvik Coromant is Coromill Plura with 50deg helix in grade GC1620, which is optimised for the finish profile milling of walls and bores.

SL70 is a quick-change tooling system that combines with Coromant Capto to provide stability when machining difficult-to-access fan casing parts, particularly when using vertical turning lathes.

Different configurations of modular building blocks give the tooling (which incorporates Jetbreak high-pressure coolant technology) support at the right clearance for various fan casing features.

Sandvik Coromant’s Xcel range offers a solution for semi-rough turning into casing shoulders.

Spools feature deep internal chambers and external blade tulip grooves.

Dampened blades in combination with Coromant Capto help overcome the tendency to vibrate.

Directional coolant provides effective chip evacuation from the groove.

Sandvik Coromant inserts are available to fit every groove shape.

The ceramic grade CC6060 is recommended as its notch wear resistance allows higher depths of cut.

RCMX carbide turning inserts for finishing complete the package of products for spool machining.

Shafts for aerospace engine applications are manufactured from high-alloy steel or Inconel.

A Silent Tool dampened boring bar programme from Sandvik Coromant is available in diameters up to 250mm with 14 x diameter length capability.

The SL70 modular blade system offers easy access into the shaft flange, while a number of pull boring solutions are available for internal features.

Coromill 316 is suitable for scallop milling on shafts.

Blisk/impellor machining takes place on five-axis machining centres with good simultaneous dynamics.

Coromill Plura is a family of conical ballnose end mills that embraces 12 new products with radii and taper options, suitable for the machining of blisk and impellor turbo parts.

The Coromill 316 ballnose exchangeable insert allows for rough machining titanium slots using point milling techniques.

Sandvik Coromant hole making solutions on blisks and impellors embrace Corodrill 846 and chamfering using Coroturn XS Fan discs.

Sandvik Coromant also provide dampened blades to machine deep internal chambers, Corocut angled inserts for difficult-to-access grooves, and tailored side and face cutters and profile end mills for tulip-slot milling.

All of Sandvik Coromant’s solutions for aerospace engine machining are detailed in its downloadable, 20-page brochure, ‘Aerospace Engine Total Component Solutions’.
