Expansion of vibration damping system with boring bars

As the use of long overhang tools becomes increasingly popular throughout the manufacturing industry, Seco has expanded its patented line of Steadyline damping tools include boring heads.

The highly rigid and stable Steadyline system effectively reduces unwanted vibrations in extreme cutting conditions via a “dynamic passive system” inside the holder body where a damping mass counter vibrates against the first flex vibration. As such, these products can perform typical long overhang operations twice as fast as traditional tools, reduce spindle stress as well as offer high metal-removal rates, smooth part surface finishes and long tool life.

Steadyline is available in 6xD, 8xD and 10xD bar sizes and a range of types, including Seco-Capto C4, C5 and C6 and HSK-T. The system also features compact boring heads with a GL connection for roughing from ø36 to 69 mm, and finishing from ø 34 to 69 mm. Furthermore, both the bars and the heads feature coolant supply channels for enhanced chip removal.

While common traditional systems use several fastening screws and devices for exchanging boring heads, the extremely precise GL connection on the Steadyline bars requires only the use of a spanner wrench to loosen and tighten the heads.

The connection’s strong, fast locking capability comes from a single inbuilt clamping ring that draws in the boring head for a secure, stable taper-face contact. Once a boring bar is set it becomes possible to mount and remount the heads without having to reset the system.
