ActiveEdge for Line Boring

Rigibore is the only company in the world that can automatically adjust multiple cutting edges on a single boring bar to within one micron on diameter.

The machining of crankshaft bearing journals requires accurate, concentric bores with the quality of the finished component directly impacting power and fuel efficiency of the engine block.

An ActiveEdge line bar is designed with 5 semi-finish cartridges which are set 0.1mm below nominal to allow the 5 ActiveEdge cartridges to finish all journals in one pass. ActiveEdge cartridges are adjusted automatically using Rigibore’s Zenith Solution.
