A servo electric cylinder converts the rotational motion of a servo motor into linear thrust via a reduction gearbox and a ball screw; it serves as the actuator for a servo press. However, a press is not merely an electric cylinder: the rigidity of the frame, pressure sensors, displacement feedback, and evaluation software collectively determine the quality of the press fit.

The standard cycle of a servo press is as follows: workpiece positioning and verification, rapid advance, contact detection, press-fitting phase, pressure holding, return stroke, curve evaluation, and data archiving. The key to operation lies not in the sequence of button presses, but in the coordination of speed, target positions, and target pressures during each phase…
Read MoreTo understand a servo electric cylinder specification sheet, you just need to focus on three key factors: maximum thrust determines what can be pressed; effective stroke determines how deep the press can go; and repeatability determines how accurately the press operates. These three factors are interdependent, so you cannot simply select the highest value for each one individually.
Read MoreMulti-stage pressing breaks a cycle into several segments, with each segment having its own independently set control method, target value, speed, and decision criteria, allowing a single machine to perform different operations such as pressing, forming, and holding pressure.
Read MoreThis is because servo presses have transformed the assembly process from one based on empirical pressure application into a programmable, measurable, and verifiable process: position, speed, and pressure are controlled in a closed-loop system throughout the entire process, and a force-displacement curve is recorded for each part.
Read MoreThe core of this replacement is not simply switching the power source from pneumatic or hydraulic to electric, but rather transforming an uncontrollable open-loop pressing process into a fully closed-loop, deterministic process, while simultaneously eliminating the on-site burdens associated with hydraulic fluid and compressed air.
