Hydraulic cylinders are controlled by inverter motor. It is good reaction,and realized energy safe and stabled ram control.
The invertor motor controls pump speed, and the servo valve controls oil flow at most appropriate level. The machine has excellent energy saving property. And it can process a wide range of works, from thin to thick plates.
COMPOSITE SYNERGY DRIVE
Servo valve is fixed on the hydraulic cylinder. Time for ram stop in an emergency is extremely shortened. Safety is also improved. Ram movement can be controlled strictly because of the monitoring system for servo valve spool position
