Damped boring bar and tool holder

摘要: A damped boring bar assembly for damping the vibrations encountered during high-speed of titanium, zirconium, and their alloys like, as well steel other metals, especially when overhang, or ratio diameter to depth bored hole, is very small. The has a weighted damper body contained within hollow elongated case, tool-holding end which closed incorporates shaped inner face with frictional sliding surface. also frictionally slidable element which, body, holds resilient in compression an internal cavity. having surface thereon engages case vibration. mechanism can be adjusted handle different machining conditions.
