Rotary finger chucks
3-turning-finger power chuck with very high axial clamping force for clamping workpieces that cannot be radially clamped.

Advantages – Your benefits

  • For purely axial clamping of workpieces
    No radial clamping components that exert forces on the workpiece
  • Workpiece contacting components can be exchanged
    Optimum adjustment to new clamping tasks
  • Optional air control available for workpiece locating surface
    Monitoring for safe workpiece clamping in large series production
  • Very good seal against penetration of chips and coolant
    Long maintenance intervals and constant clamping forces at the workpiece
  • Standard hydraulic cylinder is sufficient for chuck actuation
    Existing clamping cylinder on the machine can generally be used
  • All functional parts are ground and hardened
    Ensures a long life span

Options and special information

  • Gentle clamping of deformation-sensitive or geometrically complex workpieces
    ROTA DFF rotary finger chucks are ideal for clamping of workpieces via a purely axial clamping finger against a defined workpiece stop. It is important that the workpiece is centered in the turning center prior to axial clamping (e.g. via centering jaws or a separate centering device). The workpiece is then clamped only axially, with no radial clamping components. This achieves maximum axial run-out accuracy.
