Closing device for axial rolling head
Download Rolling system news (958 KB)
  The FETTE axial rolling heads generate the thread or required form and then open automatically after rolling. For the next thread, the thread rollers have to be returned to the working position, i.e. the rolling head has to be closed.

To make this procedure simpler and easier on turret lathes, FETTE has developed a closing device which closes the head using the machine’s coolant connection.

The closing device consists of two parts:

  • The actual closing device, fitted to the rolling head
  • The coolant transfer station, fitted to the adjacent station of the turret

To change the tool, only the adjacent station is brought into the working position and the coolant is switched on briefly: this already closes the rolling head.

Advantages of the FETTE closing device:

  • Coolant is available at every turret lathe.
  • The standard rolling head can be used, it is merely mounted on a closing bracket.
  • The closing device only needs to be pushed on the round shank of the rolling head and clamped in position.
  • Closing by means of the coolant can be integrated in the machine program by a simple function.
  • The coolant of the station where the rolling head is fitted can be used for cooling during the rolling process.
  • By dividing into two components, many rolling heads and machines can be operated at short notice by making corresponding combinations.
