Ceratizit USA has developed its MaxiMill S-Power face milling cutters with 12 insert pockets with diameters of 63 mm and double-sided indexable inserts to address the tool wear, burr formation and breakout challenges typical in cast iron machining applications. The face mill also features a specialized double-wedge clamp to ensure the indexable inserts are easy to use and securely attached.

The milling cutters’ double-sided indexable inserts offer 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. The double-sided wedge clamping simplifies quick and accurate insert changes with a single screw for each double wedge.

The MaxiMill S-Power milling cutters are available in standard diameters of 56-125 mm. A setting angle of 88 degrees permits a maximum number of cutting edges, and the indexable inserts are peripherally ground for close tolerances and high surface quality. The inserts are thicker than conventional inserts, making them stable when machining.

MaxiMill S-Power is well-suited 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 0.4, 0.8 and 1.2 mm. The grades include CTPK220, CTCP230 and ceramic.

“Our automotive and heavy industrial customers will benefit from the improved performance of the MaxiMill S-Power,” says Eric Gerringer, technical director at Ceratizit USA. “Braking systems, engine blocks, pump housings and machine tool beds are only a few examples of cast iron components that this face mill can machine efficiently.”
