a much improved machinability, due to its
100% ferritic structure and extremely fine graphite
flakes, which diminish the cutting stress. The
size of the flakes also influences the quality
of the surface finish obtained after machining.
These advantages have been documented in a study
made by the CETIM on all types of machining (dressing,
carriage, boring, drilling…) .The excellent
surface finish often allows the elimination of
reaming which is an obligation for other types
of iron. The savings in machining speed and tool
life as well as the reduction in time spent changing
tools lead to high productivity gains.
