Dapra Corporation’s precision-ground ballnose inserts with PCD tips are diamond-tipped for milling soft, nonferrous materials such as aluminum and graphite. According to the company, the inserts increase wear resistance and have an expected life as much as 100 times longer than carbide-coated inserts. The PCD-tipped inserts are precision ground to provide a sharp, accurate cutting radius. Available with 3/8", 1/2" and 3/4" diameters, the inserts are designed for use with the company’s standard steel, carbide-core and carbide-shank cutter bodies.
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.
