ANTI-VIBRATION BAR HOLDERS 

In recent years Craftsman Tools has developed a range of machine adapted tool holders specifically for deep hole boring using on a lathe.

Our holders offer compatibility with anti-vibration bars and are ideal for high force/load applications. Working together with the Silent Tools® and Steadyline™ typically allow for a boring depth of up to 14 times bar diameter.

BENEFITS INCLUDE

  • Compatibility with both Silent Tools® and Steadyline™ anti-vibration boring bars. Excellent vibration absorption properties.
  • 4x bar diameter clamping length and full radial clamping increases tool rigidity and improves cutting performance. Ideal for high force/load applications.
  • Suitable for boring up to 10x the bar diameter in depth (with 14x diameter lenght bars)
  • Range available for all of the major Machine Tool Manufacturers, including Mazak, Doosan, Mori Seiki, Okuma.
  • Available with through-tool coolant feed via removable backplate.
  • Moly-coated bore and the inclusion of jacking screws (hinge type only) make it easier to interchange both tools and reduction sleeves.
  • Craftsman Tools reduction sleeves allow the holder to accept tools smaller in diameter
  • Many holders offer larger bore sizes than the standard holders

HOLDER VARIATIONS 

Our range is designed as one of two clamping variants. Where  feasible a single piece Hinge-Style will be used, however the interfacing bolt pattern and required tool size often means a 2 piece Cap-Style has to be used. Both styles of holder will accept split reduction sleeves and are suitable for 10 x diameter boring applications.

INTELLIGENT ANTI-VIBRATION BAR HOLDERS 

Craftsman Tools' next generation of boring bar holders have been developed to take full advantage of digital machining in the 4th Industrial Revolution.

Our Intelligent Boring Bar Holders are the world's first to be fully integrated with Silent Tools™ Plus and Coroplus®, and are the optimal method for holding vibration-damped turning bars with embedded connectivity.

The brand new holders feature drilled and tapped holes to incorporate the transmission box and connection wires, as well as integrated coolant tube assembly. This allows for the quickest possible set up, and are designed to facilitate:

  • Real time feedback of cutting performance, provided to machine operator
  • Full wireless connectivity
  • Increased machining efficiency

We have a wide range available and can provide intelligent boring bar holders to fit the vast majority of machine manufacturers, including Doosan, Okuma, Mazak, and DMG Mori. For more information, contact us here.

REDUCTION SLEEVE ASSEMBLY

The same holder can clamp a range of boring bars by using reduction sleeves.

Features include:

  • Combined captive spacer maintaining 4 x diameter clamp length
  • Easy withdrawal of both sleeve and spacer
  • Aligned in the holder for ease of setting
