Feed fingers are available for all common machine types. |
||||||||
Use:
For feeding forward workpiece bars on multi-spindle automatic lathes.
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.
