Sandvik unveils cutting tool that minimize splintering on composites

Sandvik Coromant CoroMill Plura compression end mill for composites is of interest to any manufacturer machining CFRP. This innovative new tool combines positive and negative helix design to ‘compress’ the top and bottom of the component edge.

This minimizes any opportunity for splintering, a common defect when machining CFRP and many other types of engineering composites.

Suitable for edge milling applications on material with a minimum thickness of 6 mm, the CoroMill Plura compression end mill features optimized micro geometry that provides six effective cutting edges for surface finish of well under 4 µm and high material removal rates. Conventional up-milling strategies are recommended as these give less vibration. The tool is based on GC1630 grade for extended life, and comes in diameters ranging from 6.0 to 16.0 mm, and lengths (total) from 76 to 100 mm. It is also possible to get this milling cutter with diamond coating.
