At a glance: High material removal rate > 8 l/min with 32 mm diameter with HSK Soft, low-vibration cutting thanks to highly positive rake angle and increased axis angle: Higher quality, lower power consumption High stability thanks to optimally embedded PCD blades: No notching effects or protrusions Unhindered chip flow: No corners or sharp edges in the chip flute In the aerospace industry, aluminium structural parts such as frame elements or wing parts are generally milled from solid material. Often more than 90 % of the raw part is cut away. New machine generations with sufficient drive power and the necessary spindle speeds allow for an efficient high-performance machining of aluminium parts. MAPAL has developed a new range of aluminium roughing milling cutters. The OptiMill-SPM (Structural Part Machining) high-performance milling cutters have a cutting edge length that corresponds to approx. 60 % of the diameter. This represents the maximum contact depth for the high-performance milling of aluminium. Thanks to the high positive cutting edge geometry and the optimised chip spaces, the cutting force of PCD milling cutters is reduced by up to 15 %. Even when milling on standard machines, this reduction in cutting force results in more efficient machining parameters, and hence in improved performance. Bending of the tool during the machining process is prevented by the form of the milling cutter (bottleneck). A further benefit of this conical design is the clearance that is created between the wall of the part and the milling cutter shank. Particularly with deep pockets, this prevents scratching of the part wall caused by chips.
