OSG Tap & Die’s Exocarb WXS end mills are designed for milling 54 to 70 HRc at high speeds. The company says its custom nanotechnology coating, WXS, increases productivity and tool life versus TiAIN coating. The coating is said to have an increased oxidation temperature to permit greater spindle speeds, which leads to faster cycle times. In addition, the optimization of the substrate with the coating treatment increases adhesion strength, thereby decreasing the possibility of chipping.
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.
