Face Milling Platform for Cast Iron

Kennametal’s new KSSM8+™ Face Milling Platform with eight cutting edges is focused on maximum metal-cutting performance in cast irons and steel workpieces at the lowest possible cost. Cutting cast-iron parts is tough and it should be. Cast-iron pump housings, brake callipers, turbine housings, and many other parts are critical foundation components for entire industries, including automotive, heavy equipment, energy, and fluid power. Achieving the highest level of milling performance at the lowest cost per cutting edge is essential for success. The IC10 size provides a 9mm (0.354 in.) depth of cut, while the IC 12.7 achieves a 6mm (0.236 in) DOC. Both have high lead angles (88 degrees and 87 degrees, respectively), making them good choices in applications where fixture limitations or part designs call for close to 90-degree shoulders. The double-sided insert design with eight cutting edges provides users with the lowest cost per edge, while the –LD geometry’s positive rake face and honed edges result in lower cutting forces and good floor finishes in medium and finish machining. While face milling is a common, everyday metal-cutting task, it is one with many critical considerations. Depth of cut must be balanced against maximizing speeds and feeds for long tool life. High surface finish requirements must be factored into achieving high production efficiencies. That is why a range of insert grades for the new KSSM8+ platform is available for face milling steels, stainless steels, and wet or dry machining of ductile cast irons. Together with the choice of medium- and fine-density cutter bodies makes KSSM8+ the right solution in addition to the preferred low-cost choice when milling cast irons.
