The World’s Smallest Precision Finish Boring Head

The EWN 04-7 Series from BIG Kaiser is ideal for use on micro-milling machines with high-speed spindles such as HSK-E25, E32 or E40.

BIG Kaiser Precision Tooling Inc. (Hoffman Estates, IL) added the EWN 04–7 Series — the smallest precision finish boring head on the market — for use on micro-milling machines with high-speed spindles such as HSK-E25, E32 or E40.

The head features a high precision adjustment accuracy of .0005 in/Ø and .0001in/Ø through the use of a Vernier scale, and a diameter range of Ø.016 in — .276 in (Ø.04 mm — 7 mm). The product is available with the Kaiser KA1 modular connection, or with a Ø10mm straight shank, and can accept boring bars with Ø4mm shanks. The head features a maximum through-tool coolant pressure of 300 psi.

While this boring head is accustomed to micro-machining applications, it can also solve problems for companies that need a tool able to travel into deep cavities for ultra-small diameter boring. High rigidity and secure clamping of the boring bar makes it a good product for any micro boring application.

The EWN 04–7 Series adds to the variety and versatility of our micro-machining program,” says Jack Burley, the vice president of sales and engineering at BIG Kaiser. “This helps us give customers the best possible solutions for any small-diameter boring needs.”
