R & J Tool’s indexable carbide and ceramic insert sharpening process sharpens inserts by selectively grinding material to produce a new cutting edge. According to the company, this is not downsizing—the inscribed circle is not reduced and the locating surfaces are not changed. Instead, the sharpening process takes specific customer applications into account with geometries, edge preps and coating combinations that enable the same or improved performance as a new insert, the company says. The process is available on carbide and ceramic inserts for both milling and turning applications.
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.
