The Super FF (Fine and Flat) coating on the company’s new insert grades, AC820P and AC830P, is wear resistant and reduces the possibility of chip adhesion because of its smoothness. Combined with newly developed carbide substrates, the AC800P series offers high speed capabilities and a resistance to breakage when machining steels and stainless steels, the company says.
The AC820P is designed for general-purpose machining and is available with a variety of chipbreaker styles, including the high efficiency EGE style. Among P30 grades, the AC830P is recommended for applications involving interrupted cuts. According to the company, its toughness can sustain more impacts than conventional P30 grades.
Can Additive Manufacturing Increase Milling Feed Rates?
With PCD tooling, yes it can. The diamond cutting edges demand a large number flutes to realize their full effectiveness. Traditional methods for making cutter bodies limit the number of flutes, but 3D printing is delivering tools with higher flute density and other enhancements as well.
