ABSTRACT:
The vibration damping construction for boring bars comprising a cutter insert holder bar cap rigidly mounted on the end of a boring bar having a rigidly anchored cantilevered internal bar extending back within a cylindrical cavity in the end of the boring bar on which an optional number of heavy reactors are assembled with optionally varied radial clearance for relative oscillatory movement, as well as axial clearance for free independent movement and with outer radial clearance relative to the inner wall of the boring bar exceeding the maximum oscillatory movement whereby reactive oscillatory damping impact transmitted to the cantilevered inner bar will in turn be transmitted to the anchor point of the inner bar and thereby concentrated near the axial location of the cutter insert. A progressive series of reactors with progressive inner radial clearance effectively simultaneously dampen vibrations of different frequency; and various modifications provide optional and adjustable cantilevered reactor assemblies adapted to meet specific requirements.
