WAUKESHA, WI — The new MD133 Supreme milling cutter from Walter, designed specifically for dynamic milling, delivers increased process reliability, particularly during unmanned operation. It brings a heightened productivity thanks to a higher metal removal rate and a reduction in machining time. The first in Walter's projected line of dynamic milling cutters, the MD133 Supreme has diameters of 0.25 to 0.75 in. (6 to 20 mm) and cutting lengths to 5 × Dc. They are designed for operating parameters typical of dynamic milling, such as a small width of engagement and a high depth of cut facilitated by a large cutting length.
A chip breaker guarantees short chips even when working with large cutting depths. This new milling cutter is available in two different grades: WJ30RD for steel (secondary application: cast iron) and WJ30RA for stainless steels (secondary application: ISO S, N). In addition to other benefits, the MD133 Supreme is a solution for applications with difficult-to-cut materials or unstable conditions (due to machine, workpiece, or clamping).
The new milling cutter's dynamic milling strategy makes full use of the entire cutting length, giving it a very even wear pattern. In addition, heat is dissipated via the chip as much as possible, which leads to an improved tool edge life. Its special features make the MD133 Supreme interesting for high volume production environments, but also to users with smaller batch sizes. With its high level of flexibility, thanks to its excellent match to the demands of dynamic milling, render this milling cutter suitable for the diverse range of tasks required from these operations. Typical application areas for the new dynamic milling cutter line are general engineering, aerospace, energy and the mold and die industries.
