The face milling cutters from MAPAL with replaceable PCD milling cartridges are the cutters of choice to achieve the best surfaces when machining aluminium in the automotive industry. The setting and clamping system of the milling inserts has proven itself time and again in a variety of applications. Now, a new optimised generation of milling cutters for cutting at depths up to ap = 4mm has been launched at EMO 2017.
The chip guiding geometry was optimised for the new ‘PowerMill-Blue’ series and it is no longer integrated in the tool body but directly in the milling cassettes. The chips are reliably removed and scratches on the surface are eliminated. The result is even better surface finishes than ever before.
Instead of the previous central coolant supply, the cutting edges are directly supplied with coolant at the cutting point. The coolant outlet is localised in the milling cassette and as a result, the new milling cutter is also suited for MQL machining. Compared with the previous generation, noise is minimised due to a minimised tool overhang.
As for the previous generation, the milling cartridges in the aluminium tool body are accurately manufactured and guarantee a perfect flight diameter of the inserts. The milling cassettes can be interchanged with all existing PowerMill milling cutters. The PCD milling inserts can be reground several times for the highest level of cost-effectiveness.
