Gravure Chrome Polishing Machine for the Rotogravure Cylinder

HJ-GPJ Chrome polishing machine, used to polish the chrome-plated gravure cylinder, is the new full automatic numerical control model that developed by the rich experiences of designers and modern numerical control technique. Their features are rigorous structure, stable, high efficiency, easy operation, etc.

FEATURES

1. Easy operation

Centralized operation panel, pressure display, roller rotating speed display, polishing head reciprocal times display. Operator can set up and regulate parameter.

2. Effectual polishing

To meet the challenge of different technical vibration, polishing head adopts constant torque electron electrode less variable-speed, pneumatic control, cylinder push, panel governor valve regulate. High accuracy spindle and bearing ensure stationary spindle rotation, high rotary precision, frequency conversion electrode less variable-speed.

3. Save shaft material

Tape feed motor adopts constant torque electrode less variable-speed motor and reduction ratio motor, ensure polishing belt speed can inherent regulation between 2mm/min to 30mm/min.

4. High automatic complete appliance

complete appliance adopts Mitsubishi PLC control, to achieve complete appliance automatic control. Transducer adopts Fuji transducer, increase the service life of complete appliance.
