Solutions for cost-effective and high-quality machining of aerospace spools

Solutions for cost-effective and high-quality machining of aerospace spools  

The two challenging features of this component are the deep internal chambers and external blade tulip grooves.

The key to success is a combination of engineered solutions and methodology with optimized grades.

Tooling solutions for machining of aerospace spools

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

CoroCut® angled inserts to fit any groove shape

Designed specifically for reaching difficult-to-access grooves and pockets in complex components. To complement the standard CoroCut® 90-degree program, blanks are available in 90°, 45° and a T-shape for more special requirements.

Dampened blades with Coromant Capto®

To machine deep internal chambers, typically up to 150 mm, long, slender tools are required. The challenges are a tendency for vibration and removal of the chips from the groove.

One of the most challenging features has been successfully turned into a secure process due to the following:

  • An oval serration blade system for best stability and accessibility. The 100 mm (3.937 inch) high blade allows for best coolant delivery to assist in chip removal.
  • For blades longer than 4 times the width of the blade, a patented dampening device is part of the design. This allows the depth of cut to be 4 times greater than without dampening.
  • A trochoidal turning technique combined with ceramic grade CC6160, 6220 or 6230 reduces the number of machining passes required.

A secure process with more than double the productivity

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.

RCMX turning inserts for intermediate to finishing

Carbide RCMX inserts fit into the same insert pockets as ceramic, reducing the number of tools required as well as set-up time. The geometry provides low cutting forces and good chip control.
