Milling tools monoblock \ Solid carbide mill for trochoidal machining

ATORN TVC trochoidal end mill
milling tools for modern milling strategies

the new ATORN TVC end mills are ideally suited for processing various steels and
stainless steels/heat-resistant alloys using modern milling strategies. cutting
lengths of 3xD and 4xD, reinforced cores and specially developed chip breaker
geometries allow for deep operating depths with maximum process reliability.
The variable twist angles of 44°/45° and 37°/40° reduce vibrations to a mini-
mum and lead to highest surface qualities.
maximum cutting edge lengths – both types are available in 3xD and 4xD
cutting length.
Uneven twist angle
Steel = 44°/45°, stainless steel = 37°/40°

Chamfer Edge protection - all tools are manufactured with chamfer edges for
protection against wear.
chip breaker geometry – produces short chips, thus optimising
chip removal.

optimised number of teeth – 3xD tools have 5 teeth; the 4xD tools are manu-
factured with 4 teeth.
