The Big Kaiser EWN 04-7 series precision-finish boring head is designed for micro-milling machining with high speed spindles such as HSK-E25, E32 or E40. The head is also well-suited for applications in which a tool must travel into deep cavities for ultra-small-diameter boring, the company says. High rigidity and secure clamping add to the boring head’s micro capabilities.
The head is available in diameters ranging from 0.016" to 0.276" (0.04 to 7 mm) and features a high-precision adjustment accuracy of 0.0005" per diameter and 0.001" per diameter with the use of a Vernier scale. The maximum through-tool coolant pressure is 300 psi. The head is available with the Kaiser KA1 modular connection or with a 10-mm-diameter straight shank, and can accept boring bars with 4-mm-diameter shanks.
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.
