Tungaloy, which has a UK subsidiary in Cannock (www.tungaloy.com), has expanded its ‘Mill Quad Feed’ high-feed milling cutter series by adding new grades and cutter body options for its SWMT09 insert range, along with two options of insert geometries that cover various high-feed milling applications.

The ZER geometry ensures light cutting loads at large depths of cut for fewer machining passes. This is particularly effective at boosting productivity in challenging rough-milling operations of cast iron where a cutting depth can vary greatly on a single working surface. That said, the UER geometry is designed to provide the cutter with a small entry angle, resulting in thinner chips during machining and a minimised impact on the inserts’ cutting edge.

This geometry is optimised for the high-feed machining of exotic materials where long insert life is crucial.

Another particular benefit of ‘Mill Quad Feed’ is its ‘high insert density for a given diameter, due to the small size of the SWMT09 inserts. For example, there are seven inserts in the 50mm-diameter cutter.

Meanwhile, the HXSW09 modular-style cutter head is available in diameters of 25 and 32mm; and by combining these with various sizes of modular shank, these cutter heads can be used ‘in an optimal overhang length for every high-feed milling application’.

The shell mill cutter line has new diameter additions of 52 and 63mm, complementing the existing line of 40 and 50mm-diameter cutters. There is also a new line of coarse-pitch cutters for when fewer teeth are wanted in contact with the work to minimise chatter.

Insert grades have also been expanded with four new additions. These are AH3225 for steel, AH130 for stainless steel and titanium alloys, AH120 for cast iron, and AH8015 for hardened steel and Inconel.
