Bore patterns:

  • round grooves
  • smooth bores on request

Hardness:
Feed fingers are made from special spring steel. The front component with the clamping bore has a hardness of approx. HRc 60 – where this is not prevented by the partial tempering. The thread and spring areas are hardened to spring temper.

Feed force:
Feed fingers are supplied sprung together so that, when the dimensions are nominal, they pre-tension the workpiece rods. The feed force table below gives the reference values.

A hardened ground test mandrel with a tolerance of h7 must be used for checking.

Feed fingers with increased feed force can be made for an extra charge.
