When machining components made of materials with difficult cutting properties, such as turbine blades, drive parts or engine parts for the energy or aircraft and aerospace industries, round insert milling cutters are often the first choice. Until now, single-sided indexable inserts have primarily been used for this purpose. With the indexable insert size RNMX1005M0 for small depths of cut, Walter is bringing an extension for the M2471 copy milling cutter to the market – the first to feature a double-sided round insert with eight useable cutting edges. The system for milling cutters with diameters of 25 mm or more with ScrewFit, parallel shank or bore adaption is suitable for machining steel, stainless steels and materials with difficult cutting properties. Indexing using the flank face of the indexable insert ensures simple, safe handling.
The M2471 copy milling cutter brings all the benefits of single-sided round inserts to double-sided round inserts, particularly in terms of their positive cutting behaviour. To ensure that this does not negatively affect process reliability, the insert and body are designed so that their overall stability is guaranteed during use of all eight cutting edges.The technical features, as well as the eight useable cutting edges, reduce cutting material costs by up to 20%. Walter offers the new indexable insert in geometries "G57 – The universal one" and "K67 – The easy-cutting one" for medium and good application conditions, respectively. It is also available in Tiger·tec® Silver PVD grades WSM35S and WSP45S.
