Seco Tools has expanded its Steadyline vibration-damping tooling system to include large-diameter turning/boring bars that provide a reliable, plug-and-play solution for increased productivity in large and deep bore operations. The new 2.36" (60 mm) and 3.15" (80 mm)-diameter sizes are ideal for use in oil and gas applications, as well as general machining of workpieces that require tool overhangs of up to 23.62" (600 mm) or 31.50" (800 mm), respectively.

The Steadyline large-diameter turning/boring bars feature a BA connection and incorporate a BA adapter to mount GL50 turning heads. Seco says its patented and versatile GL connection features a polylobe taper-face interface for centering accuracy, 100 percent repeatability and fast tool head exchanges. The GL connection allows shops to perform both static and rotating operations with the same bar.

The advanced vibration damping system of Steadyline tooling absorbs vibrations before they spread through the bar. Once a turning bar is set, users can mount and remount tooling heads without having to reset the tool.

Steadyline is available in 6xD, 8xD and 10xD bar sizes and in a range of types, including Seco-Capto C6, C8 and HSK-T. The system also features compact boring heads with the GL connection and both the bars and the heads feature coolant supply channels that optimize chip removal.
