Renewal of the machines currently in service
By replacing old DC servo motor by new AC servo motor, decreasing machine fault and 5% increase of machining speed are expected.
Traditional DC servo motors for 3-axes of POB are replaced by the latest AC servo motors.
- Traditional DC servo motors are replaced by the latest AC servo motors leads to power-increase thanks to sharp-starting and stable performance being built upon initial tuning.
- Higher machining speed resulted by AC motor. (Tact time 3 sec/bend →2.8 sec/bend (5% faster)
- AC servomotor causes fewer machine trouble.
Servo valve of the latest version is installed to eliminate negative influence by higher hydraulic temperature over the bending-axis servo valve for large-sized hydraulic-powered machines.
* Remodeling with a new AC servo motor in this plan can extend the motor life for another ten-year span. But it should be noted that the NC needs be also upgraded to enoy this advantage.
