Walter presents the next generation of its milling tools in the form of Xtra·tec® XT. "Xtended Technology", or "XT" for short, is designed to achieve increased productivity and process reliability.
It is not just the black look of these products which distinguishes them from the previous Xtra·tec® tools; they are in fact a completely new generation of milling cutters. Walter is initially launching shoulder milling cutters and a face milling cutter from this generation – for virtually all requirements in shoulder and slot milling, in all common material groups. The most striking design feature of the new milling tools is the installation position of the indexable inserts: At a greater incline and with a larger contact surface. This reduces the surface pressure in the seat while increasing the stability. The larger screw hole cross-section stabilises the indexable insert and the longer screws which are now available hold it in place more securely. The cutter body has also been made more stable, as it now has much more material behind the insert seat.
Besides greater process reliability, the new installation position of the indexable inserts also allows for the addition of an extra tooth, thereby increasing productivity. The precise 90° shape of the shoulder milling cutters helps to reduce additional finishing operations. Clamping screws which are easier to access optimise handling and help prevent assembly errors. Another new feature are the smaller indexable inserts which can be fitted to the milling cutters. They are continuing the current trend towards reduced machining allowances. This applies even more so to the M5009 face milling cutter: it combines small depths of cut with the advantages offered by double-sided Walter Tiger·tec® indexable inserts. These inserts have eight useable cutting edges instead of the usual four. Thanks to these cutting edges, as well as a reduced number of finishing operations, the M5009 achieves increased efficiency. Innovation in sustainability: As part of Walter Green, the production and supply chain of the Xtra·tec® XT milling cutters is CO2-compensated.
