Walter is introducing three new high-feed milling cutters: The Xtra·tec® XT M5008 high-feed milling cutter for diameters of 16–66 mm (⅝–2½"), and the two MC025 Advance and MD025 Supreme solid carbide milling cutters for diameters of 1–25 mm (⅛–1"), with application ranges that perfectly complement one another.
The key characteristic for all three roughing tools is a shallow approach angle and easy-cutting geometries, which facilitate high feeds per tooth at low cutting depths. Together with the high number of teeth, this ensures high machining volumes, stability and process reliability. Furthermore, vibration tendency is reduced for long tools. The tools' shallow approach angle reduces the radial load on the tools. This means that the MC025 Advance and MD025 Supreme solid carbide milling cutters are perfectly suited to machining thin-walled connecting elements, such as hinges and struts in aircraft construction.
The MD025 Supreme is the benchmark in the aerospace industry. This is due to, first, short machining times and its versatility for smaller ISO S components; and second, the short, stable peripheral cutting edge, reduced neck and compact design, which are very advantageous for milling deep cavities. All three milling cutters can be used in the ISO material groups P, M, K and S and satisfy high demands, for example in mould and die making. The Xtra·tec® XT M5008 high-feed milling cutter enables near-net roughing and combines stability with wear-resistant Tiger·tec® cutting tool materials – for optimum cutting data and tool life, such as for milling deep pockets, grooves or freeform surfaces. The most striking feature of both solid carbide milling cutters fitted with a parallel shank or ConeFit exchangeable head is their end-face geometry, which is specially developed for high-feed milling.
