World’s Smallest Boring Head?
6. March 2013
Big Kaiser says it has produced the industry’s smallest finish boring head. Its EWN 04-7 series is designed for use on micro-milling machines with high speed spindles such as HSK-E25, E32 and E40 models.
This boring head has a diameter range of 0.016" to 0.276". It features a high-precision adjustment accuracy of 0.0005"/diameter or 0.0001"/diameter with the use of a Vernier scale. 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. Maximum through-tool coolant pressure is 300 psi. High rigidity and secure clamping of the boring bar makes it well-suited for many micromachining applications including those that require small-diameter boring deep inside cavities.
