Vibration-damping tooling range extended

Vibration-damping tooling range  extendedAlcester-based Seco Tools (UK) Ltd ( has expanded its range of Steadyline vibration-damping (long-reach) turning and boring bars and heads with the introduction of new 25mm-diameter Steadyline bars, new GL25 turning heads and new 100mm-diameter Steadyline bars — plus new rough- and fine-boring heads for Steadyline bars.

Seco says Steadyline turning bars incorporate a particularly effective vibration-damping system that allows manufacturers to turn and bore depths up to 10¥D when machining small- and large-diameter holes.

This system features a damping mass inside the tool-holder bars; when used in conjunction with short, compact cutting-tool heads, optimised vibration absorption makes it possible to use tool lengths up to 10-times the bar diameter, while negating tool chatter and preventing work interruptions.

Moreover, Steadyline allows manufacturers to quickly and easily change turning and boring tool heads, using Seco’s GL connector system.

This gives a centring accuracy and repeatability of 5µm — plus a 180deg head orientation capability, if required.

The 25mm-diameter bars with the GL25 ‘workpiece-side connection’ for turning and boring depths of 6xD, 8xD and 10xD include carbide-reinforced bars designed to tackle even the deepest tool overhang challenges, as well as Seco-Capto, HSK-T/A and cylindrical-shank machine-side interfaces.

The 16 new GL25 turning heads are aimed at general turning, recessing and back-boring applications with DN 11, CC 09, DC 07, DC 11, TC 11 and VB 11 inserts.

Larger 100mm-diameter bars accommodate existing GL50 turning heads and incorporate Seco’s Jetstream Tooling high-pressure coolant technology through BA-to-GL50 adapters.

Boring heads with BA060 and BA080 machine-side interfaces allow for the rough and fine boring of diameters from 66 to 115mm.
