Aluminium endmilling

SANDVIK has developed the CoroMill 790 specifically for milling aluminium.

The insert is said to feature a sharper as well as stronger edge; an optimised edge that flows smoothly into cut; a chipforming geometry with less frictional contact and improved chip direction; an edge with a primary relief land that dampens vibrations; and a secure, exact location and locking of the insert in cutter.

According to the company, sophisticated models and simulation had to be developed for the project to arrive at the new insert features, some of which were patented separately.

According to the company, the scope for high speed machining of aluminium with indexable insert tooling is given new dimensions.
