Vibration Damping Shell Mill Holders

As size and complexity of components creates the need to machine difficult to reach areas and deep cavities, it has become increasingly common to use long overhang tools, which tend to introduce vibration into the machining process.

As size and complexity of components creates the need to machine difficult to reach areas and deep cavities, it has become increasingly common to use long overhang tools, which tend to introduce vibration into the machining process. To address this issue, Seco Tools (Troy MI) has developed the patented Steadyline™ vibration damping shell mill holders. Steadyline features a passive dynamic damping system offering up to 3X the rigidity of equivalent solid holders, resulting in greater productivity, longer tool life, and improved quality.

The Steadyline holders are designed with the vibration absorber positioned at the front of the bar where the deflection is the highest. This feature dampens vibrations as soon as they are transmitted by the cutting tool to the bar body and prevents the vibration from spreading, thus limiting deflection of the tool at up to 5xD overhang. This allows for cutting speeds and depth of cut to be increased up to 4x that of a modular system.

Featuring coolant channels and made of high tensile coated steel, Steadyline shell mill holders are dynamically balanced and ready to use out of the box. They are available in a wide range of types and sizes -- cylindrical and tapered form, CAT, HSK, Seco-Capto, Din and BT. They are well-suited for:

• Any milling operation with long overhangs and predominantly radial forces

• Machining of deep mold and die workpieces

• Machining of complex monolithic workpieces (particularly in aerospace, automotive, and power generation applications).
