Seco introduces rough and fine boring heads for Steadyline® vibration-damping bars

Seco has extended the versatility of its Steadyline^® vibration-damping system with the new EPB™ 610 rough boring head and EPB 620 radial type fine boring head.

Featuring the patented GL or BA Connection, these heads are used in combination with Steadyline^® turning bars. This allows the same Steadyline^® bar to be used for both static turning and rotating boring operations in deep machining applications of up to 10xD.

Covering diameter ranges from 36 mm to 116 mm, the EPB 610 rough boring heads have a robust design that easily withstands the rigors of heavy, roughing operations in challenging materials. The compact EPB 620 fine boring heads cover diameter ranges 34 mm to 115 mm and features fine-pitch micro-adjusting screws that allow for precise head adjustability. Used in correlation with the Steadyline^® vibration damping bars, Ra<1 surface finishes are easily obtained, even in 10xD boring operations. These user-friendly boring heads feature hardened stainless steel bodies and through-coolant capabilities that contribute to high-precision machining and long tool life.

The highly precise GL connection also allows users to reduce preparation times via fast, simple mounting and setting procedures. This is made possible by its strong, fast locking capability via a single integrated clamping ring that draws in the tool head for a secure, stable taper-face contact. When it comes to static, turning operations, the connection has a polylobe taper interface with two 180-degree positions that orients the tool’s cutting edge either face up or face down for effective chip control.

Overall, Seco’s Steadyline^® boring bar system effectively reduces 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 than traditional tools, reducing spindle stress as well as offering high metal-removal rates, smooth part surface finishes and long tool life.
