Renewal of the machines currently in service
This is particularly applied to the client of the plan C above.
This plan suits to the ECO Benders of class 25 or large for the replacement by DDV hydraulic servo pump.
- Thanks to minimized rise of the hydraulic temperature by DDV, machining stability is increased comparing to that with servo valve.
- Electricity consumption is reduced less than a half of that with pro-renewal machine. (Down-sizing of original hydraulic pump is needed.)
- Simplified hydraulic circuitry reduces troubles with oil-leakage for smaller maintenance cost at the end.
- Thanks to down-sizing of original hydraulic pump, operation noise and fluid requirement eventually go lower.
-
By replacing old DC servo motor by new AC servo motor, decreasing machine fault and 5% increase of machining speed are expected.
-
Upon replacing with the latest NC (new TIF operator's box) and software, life extension of another 10 years span and machining speed increase by 5% are expected.
-
Upon replacing with the latest AC servo motor, NC and software, another 10 years life extention and 10% speed increase are expected.
