Vibration Damping Extensions
May 1, 2016
The damping element of the extension is close to the tool interface, where the highest deflections occur.
Long, slender extensions often have a tendency to bend and vibrate. Vibration Damping Technology (VIDAT) from Bilz is designed for use when machining long overhangs in hard to reach areas, such as deep cavities. "With an integrated damper, these extensions reduce the relatively quick vibrations for vibration- and chatter-free machining," said a company spokesperson. "Without vibration damping, the toolholder is confined to the limits of machining with large L/D ratios."
The VIDAT extensions provide more cutting depth, which increases the metal removal rate. "Compared to standard extensions with a similar projection length, the process can be performed faster with improved service life and process safety, resulting with a smoother workpiece surface," said the spokesperson.
Bilz VIDAT extensions have an h6 shank tolerance and can be both shrunk and stretched with other clamping devices for cylindrical shanks. The extensions are available with a range of tool diameters of 6 mm to 20 mm with total lengths of 210 mm or 300 mm available. The VIDAT extensions are suitable for up to 80 bar of internal coolant supply.
