Cutters suit aluminium aerospace parts

With the MD266 Supreme solid-carbide milling cutter for the aerospace industry, Walter is launching a universal aluminium specialist. The tool is suitable for all roughing, semi-finishing and finishing operations in ISO N materials.

In the new range, Walter offers the uncoated MD266 Supreme (z2/z3) with centre cut and a reduced neck from 2 to 25 mm diameter. A radius at the end of the cutting edge minimises transition steps when wall finishing. According to Walter, this concept is why the milling cutter is suitable for machining deep pockets where slot milling or ramping has preceded in the process. The internal coolant with axial outlet from 6 mm diameter maximises lubrication and improves chip evacuation. As a result, long tool life is possible with minimal build-up on the cutting edge, thereby ensuring increased process reliability.

The high operational smoothness of the MD266 Supreme is the result of a 30° helix angle and low-vibration micro-geometry. These features are a particular advantage for users because high speeds are frequently accompanied by challenging conditions. Walter’s MD266 Supreme is specifically for machining wrought aluminium alloys, particularly in applications where the focus is on high power and high metal removal rates, as well as process reliability.

Examples include the machining of structural parts in the aerospace industry, as well as components in general engineering. MD266 Supreme is capable of full slotting and ramping and, alongside its high performance and process reliability, is impressive due to its suitability for universal applications.
