1. The servo motor controls its speed and torque through the control system to achieve precise control of the hydraulic system.

2. The hydraulic system pumps hydraulic oil from the oil tank to the hydraulic cylinder through the hydraulic pump to form hydraulic energy.

3. The hydraulic oil in the hydraulic cylinder is transmitted to the piston through the oil pipe, causing the piston to move, thereby realizing the processing of the workpiece.

4. The control system detects the position and pressure information of the hydraulic cylinder through the sensor, and adjusts the working state of the servo motor in real time according to the set parameters, thereby accurately controlling the processing process of the hydraulic press.

5. When the processing is completed, the control system stops the servo motor, turns off the hydraulic pump, and releases the hydraulic energy of the hydraulic system to complete the processing process of the workpiece.
