TECNOFIL Spa: Automatic reworking machine for tungsten carbide dies
Tecnofil S.p.A. has been designing and manufacturing wire-working machinery since 1994, offering cost-effective solutions in the wire industry.
The latest developed machine is the ADR-4.
Tecnofil ADR-4 is a machine for full automatic reworking of Tungsten Carbide dies, using CNC technology to grant highest productivity, reliability and die geometry precision.
The line is composed by:
- Input die magazine holding up to 20 pieces
- Electronic control panel with PLC and Touch Screen to set working parameters
- Full automatic die shifting along the 3 working stations (cone grinding, cone polishing, cylinder calibration)
- Full automatic identification and selection of input/output dies
- Automatic diamond paste feeding
ADR-4 line is working as follows:
1st station – CONE GRINDING
The line picks one die from the magazine and insert in the rotating pliers; the machine automatically sets the contact point and then starts grinding the dies.
The control of die diameter is made by adjustable steps to get highest precision level.
2nd station - CONE POLISHING
Die is picked from Grinding Station and is delivered to the rotating pliers of the polishing station. Diamond paste is automatically inserted in the die, then the machine sets the contact point and starts polishing the die.
Polishing pin can be automatically regrinded after the desired number of cycles.
The control of die diameter is made by adjustable steps to get the highest precision level.
3rd station - CYLINDER CALIBRATION
Die is picked from Cone Finishing station and is delivered to the rotating pliers of the Cylinder Calibration.
Diamond paste is automatically inserted in the die, then the machine sets the contact point and starts polishing the cone by vibration and position control.
The re-worked die is placed in the finished dies magazine.
Technical Features:
Die diameter range: from 0,40 to 6,00 mm
Production speed: 50 dies/hour
Dimensions: Height 180cm – Width 70cm – Length 250cm
Electrical Power: 220 V Monophase.
Tecnofil ADR-4 line is completely automatic and user-friendly, it achieves highest efficiency with lowest personnel intervention at very competitive conditions.
