Key to our servo press : Closed loop control with own developed sensor and algorithm.
Introduction of Servo Press System
The precision CNC servo electronic press, commonly referred to as a servo press, servo pressing machine, servo press lathe, electronic press lathe, or electronic pressure machine, operates based on the principle of driving a high-precision ball screw with a servo motor to perform precise pressing and assembly tasks. It enables full closed-loop control of pressing force and insertion depth during the pressing process, thereby achieving precision pressing with online quality management.

Servo presses primarily operate in two modes: pressure mode and position mode.
Pressure Mode: In this mode, motion control is achieved through software programming. The instructions are transmitted to a CNC application module, which drives the servo motor via a servo driver. The motion of the output end is controlled through a transmission mechanism. After the press stroke, the pressure sensor provides an analog signal feedback based on the strain. This signal is amplified, converted from analog to digital, and output to the control system/PLC for real-time pressure monitoring. The servo motor encoder provides position feedback signals, ensuring precise position monitoring.
Position Mode: Here, the servo motor drives a high-precision ball screw. By controlling the motor’s rotation angle, the position of the press head is accurately managed. A high-sensitivity pressure sensor mounted at the presshead collects real-time pressure data, achieving closed-loop control of the pressure. High-speed data collection of position and pressure during the pressing process enables precision pressing, online quality evaluation, and digital management of process data.
