Schunk’s Tribos-Mini toolholder is designed to clamp small tool shanks consistently along the entire axis and eliminate troublesome collets, collet nuts and inconsistent tool clamping. The toolholder clamps 0.3-mm tools for challenging applications including machining medical, dental and micro-level parts.
To enable high rpms and increased feed rates, the toolholder features runout accuracy of less than 3 microns and a balance grade of G2.5 at 25,000 rpm. It uses a polygon form in the clamping bore to generate the direct clamping, without the influence of an operator. The holder is inserted into the press, and the cutting tool is released in less than 30 sec., the company says.
