Line Boring Basics

Line boring, also known as is an engine machining process that enlarges a hole that has already been cast, making the centerlines of two or more bores collinear to create perfectly straight and aligned bores. A line boring machine performs this task using one or more cutting tools held within a boring head. Line boring machines are also used for tapering holes and machining the outside face of the workpiece using a facing head. 

Line Boring Applications

Line boring machines are used on a wide range of projects, with some common examples including transfer gearbox housings, driveshafts, hinge pins, gearboxes, and turbines.

Line Boring Sizes & Power

Line Boring is capable of machining bores as small as 1.5” and up to 80” in diameter. Most line boring machines are hydraulically powered; others use pneumatic or electric power. Line boring offers a wide range of speeds from 0-25mm per minute and a hand-feed revolution of 2mm.
