Solutions for cost-effective and high-quality machining of aerospace combustion casings

Combustion casing

​Typically made from Inconel or Waspaloy, these most challenging of materials pose difficulties, not so much in the turning operations, but particularly with the amount of milling required in manufacturing this component and the large amounts of material to be removed.


Tooling solutions for aerospace combustion casings

CoroMill® Plura solid carbide end mills for high feed face milling and full slotting

CoroMill® Plura is a range of high-quality solid carbide end mills that offer productive, efficient and perfectly reliable milling solutions.

CoroMill® Plura with grade 1610 provides exceptional metal removal rates in full slotting and roughing operations with large cutting width. Thanks to the optimized face geometry, more than double the feed per tooth can be achieved compared to regular end mills.

CoroMill® 300 light-cutting face and profile milling cutters

Helical ramping of larger diameter holes with CoroMill® 300 is a very secure and productive method in this case. The cutting forces are much lower than for drilling operations, which also struggles with the interrupted exit into the bore.

For rough milling around a boss, use CoroMill® 300 with a roll-in programme combined with round inserts to reduce notch wear and allow high feed rates.

Grade S30T – designed for challenging super alloy machining

Grade S30T is a PVD-coated carbide grade​ optimized for titanium milling; excellent for finishing to light roughing. This thin-coated grade enables very sharp cutting edges that resist fatigue and micro-chipping, allowing the cutting edges to be preserved for longer time in cut at higher cutting speeds.

Ceramic turning

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