ZOLLER »tribos« is a presetting, measuring and shrink-clamping system equipped with the Schunk TRIBOS clamping system. Especially designed for shrinking of tools to nominal length in polygonal TRIBOS power shrink chucks as well as for presetting and measuring tools of all types. The TRIBOS clamping unit is automatically guided to the tool holding fixture and moved back into its original position after the clamping/unclamping procedure. It doesn't get any faster, more accurate and convenient than with ZOLLER »tribos«!
