CC couplings

The tool holder coupling developed and patented by Eppinger is used to compensate for symmetry inaccuracies of the machine to the tool holder.

A better transmission of potential forces is given by this coupling.


Your advantages with CC couplings - overview:

  • Increased tolerance accuracy in the insertion of the coupling
  • No offset tool drive to the machining spindle of the tool holder
  • Minimization of radial forces on the bearing points
  • Reduction of vibrations on the machine side - transferred to the tool insert
  • Reduction of temperature & noise generation
  • Easy replacement of the coupling
  • Minimisation of the concentricity error
  • Longer service life of the tool holder bearing
  • Improved surfaces
