Mini Toolholder Clamps 0.3mm Tools


The TRIBOS-Mini directly clamps the smallest of tool shanks consistently along the entire axis. Machining medical, dental and micro level parts are the most challenging applications faced today. This innovative toolholder from SCHUNK eliminates troublesome collets, collet nuts and inconsistent tool clamping.

With run-out accuracy of less than 3 microns and a balance grade of G2.5 at 25,000RPM, high RPMs and fast federates are achievable. Unique in the proven TRIBOS design is the direct clamping through the elasticity of the tool holder material. The patented TRIBOS technology utilizes a polygon form in the clamping bore to generate the clamping.

Cutting tool clamping results are simplified without influence of operator. The holder is inserted into the TRIBOS press and cutting tool is released in less than 30 seconds.

TRIBOS-Mini offers all of the benefits of the TRIBOS family, with an extensive line of holders and extensions. No longer are compromises necessary when clamping the smallest of cutting tools.
