Automatic Die Reworking Machine


Product categories: Various machines and accessories 

Automatic Die Reworking Machine
Automatic Die Reworking Machine

Automatic machine for tungsten carbide dies reworking and calibration, with CNC technology to guarantee:

High positioning precision

Geometry precision (Cone, Meeting point, Cylindrical part length)

The line is composed by:

  • 20 pieces storage unit for dies to be reworked/rough dies
  • Electronic control panel with PLC and Touch Screen to set working parameters
  • Full automatic die transition along the working stations (cone grinding, cone polishing, cylinder calibrating)
  • Full automatic control system to select non-conforming dies
  • Automatic diamond paste feeding
  • Automatic system for diameter stamping
  • Switchboard

Station 1 – CONE GRINDING

The actuator picks one die from the storage unit and insert it in rotating pliers; the machine automatically sets the contact point and then starts grinding the die.

The control of die diameter is made by adjustable steps to get the highest precision level.

Station 2 - CONE FINISHING

The actuator picks the die which has been previously grinded, put it in the second station and automatically fasten it by rotating pliers. A small quantity of diamond paste is automatically applied, then the machine sets the contact point and starts the process.

The control of die diameter is made by adjustable steps to get the highest precision level.

Station 3 - CYLINDER CALIBRATION

The actuator picks the die from the Cone Finishing station and delivers it to the rotating pliers of the Cylinder Calibration. A small quantity of diamond paste is applied, then the machine sets the contact point and starts the process by vibration and position control.

Station 4 - DIE STAMPING
