STEADYLINE® FOR TURNING, BORING & MILLING REDUCE VIBRATIONS & INCREASE PRODUCTIVITY

OVERCOME TOOL OVERHANG CHALLENGES When using long overhang tools to machine difficult-to-access areas, such as deep cavities or sections of large, complex monolithic workpieces, vibration often becomes an issue. Unless, you use the patented Steadyline® damped tooling from Seco®. Steadyline® products, which include cost-effective milling holders as well as turning and boring bars, perform typical long overhang operations twice as fast as traditional tools. Plus, these highly productive vibration-damping solutions offer high metal-removal rates, smooth part surface finishes and long tool life...

VIBRATION CHALLENGES IMPACT OF MACHINING VIBRATIONS UNDERSTANDING YOUR CHALLENGES As large, complex workpieces with deep cavities have become more common, manufacturers must contend with machining difficult-to-access features that require tools with long overhangs. Traditional approaches are not economically acceptable in these scenarios, as high levels of vibration impact the cutting process. Negative effects of vibrations include: • Poor surface quality • Unacceptable inaccuracy • Excessive noise • Disproportionate tool wear • Machine tool damage (e.g. spindle, etc.) • Reduced material...

STEADYLINE® OPERATING PRINCIPLE In the Steadyline® system the vibration absorber is positioned where deflection is highest, at the front of the bar. The absorber damps vibrations as soon as they are transmitted from the cutting tool to the body of the bar. This prevents them from spreading along the bar, thus limiting the deflection of the tool. The result is greater rigidity that ensures high stability even with extreme cutting conditions that dramatically increase the chip removal rate.

TURNING & BORING FLEXIBLE & EFFICIENT TOOL CHANGE SYSTEM TURNING RANGE WITH A MODULAR CONNECTION (GL & BA) STEADYLINE® BAR • A variety of Steadyline™ bars, to cover a wide range of customer applications • Available in seven metric sizes: ø25, ø32 mm, ø40 mm, ø50 mm, ø60 mm, ø80 mm and ø100 mm, and equivalent imperial sizes 1.0“, 1.25“, 1.5“, 2.0“, 2.5“, 3.0“, 4.0“ • Available in three lengths: 6xD, 8xD, 10xD • Shank connection: Seco-Capto™, HSK-T/A and cylindrical GL TURNING HEADS AND GL CONNECTION GL turning heads offer a compact, flexible and modular tool changing system for internal...

TURNING & BORING BA-CONNECTION On larger sizes of Steadyline® bars (from ø60 mm), BA-to-GL adapters are used to mount GL50 turning heads. Therefore, tool inventory can be reduced as current GL50 turning heads can be mounted on larger size Steadyline® bars. BA-to-GL adapters are available with two offset dimensions: a short one for minimum bore size requirements, and a wider one to create additional chip space between the bar and the inside diameter of the bore. • Available in: metric: ø60 mm, ø80 mm and ø100 mm inch: ø2,5” and ø3.00” • Each has two offset sizes for lower bore sizes and...

TURNING & BORING OPTIMISING YOUR RETURN ON INVESTMENT TURNING RANGE SELECTION To achieve perfect application processes with Steadyline®, Seco® offers a wide range of inserts for turning, threading and grooving. Our inserts include adapted chip-breaker geometries and a selection of solid carbide grades and PCBN, ensuring a perfect match for every application. This versatility boosts productivity and allows manufacturers to adopt greater degrees of flexibility in their processes when machining materials ranging from aluminium to hardened steel. RANGE SELECTION

TURNING & BORING MACHINE CLAMPING RECOMMENDATIONS Our first recommendation for clamping the bars onto the machines is to use bars with Seco-Capto™ machine side connections. Second choice is the bars with HSK-T/A machine side connections, as both these solutions provide several benefits: • Maximum stability thanks to the taper-face system and higher bending resistance • High positioning accuracy of cutting edge, etc. While using the third choice, the cylindrical bars, Seco® strongly recommend to clamp on the marked cylindrical clamping area ensuring the full 4xD clamping lengths using split...
