New milling cutters for high-volume machining of aluminium

The EMO in Hanover is on the international trade fair schedule in September – Mapal will present new machining solutions on around 480 m2.

In addition to the focus sectors of automotive, aerospace, fluid power technology and die and mould making, the focus will be on innovations 2024, the recently launched online shop and the topic of sustainability.

Numerous machining solutions for different industries and applications will be presented on the Mapal stand. The focus is on the automotive sector, including solutions for electrically driven vehicles, aerospace, fluid power technology and die and mould making. Mapal will also be showing innovative tools and clamping chucks that take into account the topics of energy efficiency, resource conservation and safety. 

Particularly interesting for use on high-performance machines 

The product novelties to be shown are milling cutters for high-volume machining of aluminium, “a real highlight – also for the aerospace industry,” promises Jacek Kruszynski, head of Technology at Mapal Group. The two milling cutter series in solid carbide and with indexable inserts are particularly interesting for use on high-performance machines. 

With the new solid carbide roughing milling cutter OptiMill-Alu-Wave 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 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. 

For larger diameters, the new NeoMill-Alu-QBig indexable insert milling cutters are a highly economical solution. In order to achieve as large as 18 litres per minute, the new aluminium volume cutter is designed for use at speeds of up to 35,000 rpm (with a diameter of 50 mm). The NeoMill-Alu-QBig achieves surface finishes of Ra 0.8 µm and Rz 4.0 µm for roughing and finishing even with high chip volumes.
