Head start

05/01/2011
Adjustable finish boring heads allow for a range of diameters to be machined with one tool. Finish boring can take some time but achieves tight hole tolerance and fine surface finish requirements. And if a fine finish and tight tolerance are not required, rough boring might suffice.

For practically any large-diameter boring job, there is a system that can get the job done

05/01/2012
Boring is a common hole finishing operation, but boring large-diameter holes is a bit of a niche market. “Depending on the industry, you may only find a handful of shops in some areas capable of doing this type of work,” said Ron West, global product manager for Kennametal Inc., Latrobe, Pa. “They have the larger equipment necessary to do this type of work on a regular basis.”

Mapal Boring Bars

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.

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.
