MAPAL is taking full advantage of the performance of the quickest machines available on the market with the new solid carbide roughing cutter OptiMill-Alu-Wave for aluminium materials, achieving a material removal rate of up to 21 litres per minute. At the same time, it is of course also possible to use the high-volume milling cutter on less powerful machines. The tool manufacturer is thus taking into account the fact that aeroplane parts are often manufactured on machines with spindle outputs between 40 and 80 kW, for which there was previously no suitable milling cutter in the portfolio.
The OptiMill-Alu-Wave is not only ideal for aerospace structural parts but is also suitable for applications in the automotive field and general machining. For the product launch from the EMO trade fair onwards, diameter ranges from 12 to 25 mm with projection lengths of 3xD, 4xD and 5xD are available. A configurator makes further variants possible, which also supports close-contour roughing.
The new indexable insert milling cutters NeoMill-Alu-QBig are a highly economical solution for larger diameters. In order to achieve as large a material removal rate as possible of up to 18 litres per minute, the new aluminium volume milling cutter is designed for use at spindle speeds of up to 35,000 rpm (with a diameter of 50 mm). For a tight fit despite high centrifugal forces, screws with increased tensile strength are used to hold the indexable inserts firmly in the prismatic seat. In addition, countersinks on the indexable insert ensure weight savings. MAPAL has fitted the tool body with a fine balancing system. Four threaded bores enable precise adjustment in order to protect the machine spindle at high speeds and achieve the highest possible surface finishes.
With the solid carbide milling cutter OptiMill-Alu-Wave and the NeoMill-Alu-QBig indexable insert milling cutter, MAPAL showcases a complete range of products from 12 to 63 mm for high-volume machining of aluminium materials.
