Seco adds turning bars to Steadyline™ vibration damping system
9/29/2014 8:00:00 AM

Fagersta, September 2014 – Following the success of its Steadyline milling holders, Seco is adding turning bars to this patented line of damped tooling that brings excellent productivity results to a wide variety of long overhang machining operations. The new patented GL connection on these turning tools makes it possible to perform rotating and static operations with the same bar. 

These highly rigid and stable turning bars effectively reduce 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 reduce cycle times by up to 50% in typical long overhang applications, reduce spindle stress as well as offer high metal-removal rates, smooth part surface finishes and long tool life.

The extremely precise GL connection on these turning bars has a polylobe taper-interface with two 180-degree positions that orient the tool’s cutting edges either face up or face down for effective chip control.

The connection also has a strong, fast locking capability that is made possible via a single inbuilt clamping ring that draws in the tool head for a secure, stable taper-face contact. Once a turning bar is set it becomes possible to mount and remount tooling heads without having to reset the system, and the GL connection on the Steadyline turning bars requires only the use of a spanner wrench to loosen and tighten the tool heads.

Available in 6xD, 8xD and 10xD, a range of types, including Seco-Capto C4, C5 and C6, and a broad selection of turning heads for CN, DN, WN, CC, DC, TC, TN and RN inserts as well as heads for Snap-Tap® threading, these turning bars can handle a variety of applications and operations, including roughing, finishing, threading and grooving. Furthermore, these bars feature coolant supply channels for enhanced chip evacuation.
