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.

Blade groove on spool

Inserts to fit every groove shape.

To complement the standard CoroCut 90 degree programme, blanks are available in 90,45 degree and T-shape for more special requirements.

Angled inserts for aerospace access

 

 

 

​Ceramic grade CC6060 - an optimizer for increased productivity

  • Excellent resistance to notch wear allowing for higher depths of cut to be taken compared to other ceramics
  • Long lengths of cut
  • Profiling and pocketing using trochoidal turning
 
 

RCMX turning inserts for finishing

  • Carbide RCMX insert fits in same insert pocket as ceramic, reducing number of tools required and set up time
  • The geometry provides low cutting force and good chip control
  • S05F for HRSA or H13A for titanium
