Problems solved by technology

[0002] Electro-hydraulic servo valves have been widely used in hydraulic servo systems. The spool of the servo valve is mainly ground by a precision cylindrical grinder. Then manual deburring, this traditional process has problems such as low processing efficiency of the working edge, easy damage to the integrity of the working edge during the manual deburring process, and high scrap rate of the workpiece.

At the same time, there are currently some other related new technologies for workpiece deburring, such as numerical control deburring systems, robot-based deburring workstations, etc. Most of them use new automation equipment to replace traditional grinding machine equipment and replace manual completion of the entire process of workpiece deburring. To a certain extent, the efficiency of the deburring process is improved; however, for the deburring process of the servo valve core, it fails to combine the detection and feedback of the performance indicators of the workpiece product at the same time, so it is not suitable for the industrial batch processing of high-precision servo valve products production line, there are large application limitations
