Hydraulic Expansion Tools

 Special expansion techniques and the name SCHUNK have been synonymous for more than 18 years. If workpieces or tools have to be clamped with the highest precision in relation to T.I.R. accuracy, repeatability or positioning accuracy, SCHUNK can offer precise solutions. No matter if a maximum clamping force or fine adjusted clamping is necessary, there is practically no application for which SCHUNK has not built an expansion tool.  Typical applications include drilling, milling, reaming, turning, grinding and measuring.   Problem solutions have also helped to create new applications, e. g. tooling for production lines, where tools are clamped in holders for several months, without loss of holding force.
