BIG KAISER Introduces the World's Smallest Precision Finish Boring Head

Hoffman Estates, IL – BIG KAISER has announced the addition of 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"/Ø and .0001"/Ø through the use of a Vernier scale, and a diameter range of Ø.016"-.276" (Ø.04mm-7mm). 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, BIG KAISER vice president of sales and engineering. "This helps us give customers the best possible solutions for any small-diameter boring needs."
