Seco’s new Square 6 shoulder milling cutter uses trigonal inserts with six cutting edges to boost productivity and lower the cost per insert edge. The inserts are available with three insert geometries and three pitches to allow the tool to be used for a variety of general machining operations, such as face milling, contouring, plunging, slotting and shoulder milling in steels, cast irons and hard materials. This flexibility allows users to carry less tooling inventory and reduce tool changes to boost productivity, the company says.
The cutter bodies come in diameters ranging from 40 to 160 mm. The bodies are nickel coated to extend tool life and are pre-hardened to help achieve tight machining tolerances for precision parts. The bodies are offered in normal pitch in addition to coarse pitch for unstable conditions and close pitch for rugged machine tools.
Inserts can be set to achieve a true 90-degree setting angle that creates true 90-degree walls without secondary operations. The inserts lock into place with a center screw located in the same direction as the cutting forces. Insert geometries include ME09 for stainless steel, M13 for steel and cast iron and MD15 for hard materials requiring high cutting speeds. Each of the insert styles features two different corner radii. An R0.8 radius is appropriate for normal conditions while the R1.6 is designed for tougher cutting applications.
