Iwaki, August 2021 — Tungaloy has introduced AddDoFeed small diameter high feed milling cutter series in diameters ranging from 8 to 25 mm (5/16″ to 1″).
AddDoFeed offers high feed milling capability for small parts machining, with the same cost efficiency and high productivity benefits of the renowned DoFeed solutions that have been around for over a decade.
Solid carbide end mills are a common approach for milling small parts. However, for slotting or pocketing applications that remove relatively large volume of stock, it is unproductive to use these small diameter solid end mills. Due to their low bending stiffness, the tool body cannot sustain the heavy radial force generated when feed is increased in an effort to gain better cycle time.
AddDoFeed uses minimal Size 02 inserts of 4 mm (5/32″) inscribed circle and offers close pitch cutter bodies that boast unrivaled insert-per-diameter density for a small diameter indexable cutter. This allows a 16 mm (5/8″) diameter body to carry four inserts and 25 mm (1″) seven inserts for higher feed rates and increased productivity.
These tiny AddDoFeed02 inserts carry all key features that the DoFeed insert has been delivering, including economical double-sided insert with four effective cutting edges, optimal inclination on the cutting edge that enables smooth chip evacuation, and large positive rake that provides light cutting and process security. All these features make AddDoFeed an extremely productive solution for machining small parts in various material groups.
The new AddDoFeed products complement and empower Tungaloy’s existing high feed milling concepts. 21 new items of small sized and close pitch cutters are now available in addition to the current DoFeed series of medium diameter cutter range represented by Size 03 inserts and large diameter range with Size 06 inserts. The cutter series is now a highly productive solution, over more extensive application areas, in various materials groups.
