Seco Steadyline turning barsClick image to enlarge

Seco has launched a new line of turning bars to its Steadyline family, that feature patented damped tooling the company says provides excellent productivity for a range 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 rigid and stable turning bars reduce unwanted vibrations in extreme cutting conditions. This is accomplished via a "dynamic passive system" inside the holder body where a heavy metal mass counter acts vibrations created by the holder's flex during machining operations. Steadyline products can perform typical long overhang operations with higher productivity then traditional tools, reducing spindle stress as well as offering high metal-removal rates, smooth part surface finishes and long tool life.

The 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 integrated 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.

While common traditional systems use several fastening screws and devices for exchanging tooling heads, 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. In addition, these bars feature coolant supply channels for enhanced chip evacuation.
