Hi-PosDeka, a new family of face mills from Ingersoll Cutting Tools, features 10 cutting edges per insert. The cutters are available in two insert densities, with four carbide grades. The 20-degree lead angle (with chip forming technology on the insert) allows chip loads to 0.015" in steel.
These general-purpose inserts include a 0.055" wiper flat for producing favorable, one-cut finishes to 63 rms. Custom wiper inserts are also available to achieve finishes of 20 rms.
Editor PickCan 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.
