Rotating Head Punches

Εκδήλωση Ενδιαφέροντος

Rotating head punches were designed to significantly extend the life of the shaped and multi-tip tooling with fixed key positions.

They provide more bearing surface for enhanced head wear and reduce gouging that is common in shaped or multi-tip punches with fixed key positions. Natoli’s optional rotating head punches also:
  • Increase tablet press operation speed
  • Avoid weight variations
  • Use a two-part punch configuration to significantly extend tool life
  • Reduces back angle gouging commonly seen with shaped or multi-tip punches with fixed key positions
  • Prevents binding at the pull down compression and ejection cycle of the tablet press. Rotating head punches are designed for shaped and multi-tip tooling with fixed key positions. Normally. the punches do not rotate and wear is concentrated at a single point, leading to premature head wear in that area.
The rotating head provides a two-part punch configuration. The head of the punch rotates independently to the keyed punch body. This creates increased contact surface area between the cam and punch head.
Back angle gouging is therefore drastically reduced, allowing for less head wear and longer punch service life.
