NeoMill-Alu-QBig mills aluminium with a material removal rate of 18 litres per minute

With its indexable insert milling cutter NeoMill-Alu-QBig for aluminium materials, MAPAL is taking full advantage of the performance of the fastest machines available on the market, thus achieving a material removal rate of more than 18 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 aircraft 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.

In order to achieve as large a material removal rate as possible, 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.
