Solutions for cost-effective and high-quality machining of aerospace turbine discs

Turbine disc

Aerospace turbines must withstand extreme temperatures and pressure differences. They are therefore made of advanced materials, such as nickel-based super alloys (e.g. Inconel 718, Waspaloy and Udimet 720).

Nickel-based super alloys are excellent due to their high temperature- and stress-resistant properties. It is important to apply best-practice strategies, as these materials are demanding to machine.

Tooling solutions for aerospace turbine discs

Grade GC1105 – designed for the challenge of super-alloy machining

GC1105 provides secure, reliable, quality machining, even flank wear and true versatility in all application areas.

Reliability in intermediate-stage machining through superior notch-wear resistance combined with good edge-line toughness.
Guaranteed accurate, high-quality performance in last-stage machining provided by our razor-sharp, ground inserts and our state-of-the-art thin coating with excellent adhesion.

Grade GC1105

Ceramic turning

Ceramic grades CC6220 and CC6230 are designed specifically for the challenges of new HRSA materials, where whisker ceramics and SiAlONs fall short. They are capable of higher cutting speeds, contributing to reduced cost per component. For high metal removal rates in pocketing and profiling applications, choose grade CC6160.

The modular SL70 tooling system for seal fin turning

Due to tough material, accessibility and productivity, round inserts offer the best method and are used in both roughing and finishing.

CoroTurn® SL70 blades are designed to fit the typical profiling and pocketing features
The oval coupling offers excellent stability and accessibility
All radial and axial clearance requirements are covered in a compact program
Multi-task and vertical turning lathe requirements are met with Coromant Capto® sizes C5, C6 and C8
Carbide RCMT and CoroCut® grades have high-pressure coolant as standard

CoroTurn® SL

CoroCut® 1-2

Finishing profile with SL70 CoroCut® HP S05F

For highest productive finishing with excellent surface integrity and dimensional accuracy, the combination of SO5F and CoroCut® RO geometry sets the standard for critical part finishing.

Scallop milling solutions

There are two powerful tools available for this challenging feature, and chamfering solutions and inserts are available for both product families.

Use the exchangeable-head system with CoroMill® 316 for stable roughing of the scallop feature.

The CoroMill® Plura High Feed Side (HFS) milling concept, combined with a dedicated machining strategy, is an efficient solution for increasing tool life and avoiding burr formation.

CoroDrill® 860 with -SM geometry for highly secure drilling in super alloys

When drilling nickel-based super alloys, many things need to be taken into account. Process security is among the most important criteria, along with repeatability, hole tolerance and quality. CoroDrill® 860 with -SM geometry delivers these using a robust design, a high-quality edge and a wear-resistant top coating.
