Spool

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

A combination of engineered solutions and methodology with optimised grades are the key to success.

​Dampened blades with Coromant Capto®

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

Turning one of the most challenging features into a secure process has been achieved by:

  • Oval serration blade system for best stability and accessibility. The 100mm high blade allows for best coolant delivery to assist in chip removal
  • For blades longer than 4x width of the blade a patented dampening device is part of the design. This allows depth of cut to be 4 times greater than without dampening
  • Trochoidal turning technique combined with ceramic grade CC6060 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, capable of higher cutting speeds, contributing to reduced cost per component. For high metal removal rates in pocketing and profiling applications, choose grade CC6160.
