CHALLENGE: Overcome the concerns of applying fixed-pocket, brazed-PCD boring tools. SOLUTION: Special "one-shot" adjustable boring tools that accept replaceable PCD inserts.

The aircraft industry now has the means to precisely machine multilayer material combinations. These combinations, called stack materials, include several thin layers of different materials. Aircraft skin, for example, could consist of titanium, aluminum and composite layers, according to Lee Coleman, automation division manager for Suhner Manufacturing Inc., Rome, Ga.

Wohlhaupter Corp. has made specifying the most-effective boring tool configurations quick and easy. Wohlhaupter's Tool Architect is a powerful tool selection program that will identify and specify boring tool configurations based on end user specifications.

Troubleshooting machining operations can be a daunting task, especially boring operations. This is because when machining the outside of a part, you can see what causes the tool to fail. However, when a tool is buried in a hole, as is the case when boring, you can't see what is happening to the tool.

When it comes to highly accurate machining technology, jig boring is better. So say proponents of the century-old machining technique. In the early part of the last century, jig boring started as a better way to make holes. But the technology has since evolved into a more-versatile machining option.

To make the fine machining of the crankshaft bearing journals on a machining centre economical, line boring bars are often used. With an innovative concept, MAPAL has been able, in collaboration with a machine manufacturer, to optimize this processing in several ways: Compared with conventional line boring bars, quality can be increased, processing can be sped up, and tool service life can be increased, all thanks to the new line boring bars with compensation-enabled cutting edges.
