CERATIZIT developed its new MaxiMill – S-Power face milling cutters with 12 insert pockets at Ø63mm and double-sided indexable inserts to handle the tool wear, burr formation, and breakout challenges typical in cast iron machining applications. Plus, the face mill includes an innovative double wedge clamp to ensure the indexable inserts are easy to use and securely attached.
“Cast iron machining challenges force many shops to settle for low feed rates,” says Eric Gerringer, CERATIZIT USA, Technical Director. “With an optimal number of cutting edges, the MaxiMill – S-Power allows for higher feed rates while also improving surface quality and reducing burr formation.”
The milling cutters’ double-sided indexable inserts boast eight cutting edges and are made from premium substrates with Dragonskin coating for high performance and smooth cutting action. Robust insert seats together with the double wedge clamps provide secure insert retention along with low axial and radial run-out.
The wedges are fitted with anti-twist protection, and for optimal clamping, there are separate clamping wedges for each holder diameter. Furthermore, the double-sided wedge clamping makes it easy to quickly and accurately change inserts as there is a single screw for each double wedge.
The MaxiMill – S-Power milling cutters are available in standard diameters of Ø56 to Ø125mm. A setting angle of 88° permits a maximum number of cutting edges, and the indexable inserts are peripherally ground for close tolerances and a high surface quality. The inserts are thicker than conventional inserts, which makes them extremely sturdy.
MaxiMill – S-Power complements existing face milling systems from CERATIZIT and is ideal for machining cast iron grades such as ductile cast iron, compacted graphite iron, and gray cast iron. The range of indexable inserts includes ISO P/K with cutting edge geometry M and offers corner radii of 0.4mm, 0.8mm and 1.2mm. The grades include CTPK220, CTCP230 and ceramic.
“Our automotive and heavy industrial customers will benefit from the higher performance of the MaxiMill – S-Power,” says Gerringer. “Braking systems, engine blocks, pump housings, and machine tool beds are only a few examples of cast iron components that this face mill will machine efficiently.”
