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.
