Problems solved by technology

[0003] At present, the damage of burrs to the hydraulic valve body is mainly manifested as: 1) causing internal and external leakage
When assembling the hydraulic valve, the burrs at the place where the seal is installed or where the seal is assembled may easily cause the edge of the seal to be trimmed or even broken, and then cause internal and external leakage of the hydraulic valve; 2) Block the oil circuit and cause system failure
There are many feedback oil circuits and control oil circuits in the existing hydraulic valve body structure. These oil circuits are generally composed of small deep holes, and the burrs that have not been cleaned are washed away by high-pressure oil, which is easy to block the control oil circuit, and then Cause hydraulic system failure; 3) Contaminate oil, cause failure of other hydraulic components
The burrs are washed away by the liquid flow, contaminate the working oil, and have adverse effects on precision components such as pumps, motors, and oil cylinders, resulting in failures such as pump plunger sticking and oil cylinder scuffing.
4) It affects the positioning accuracy of subsequent processes during processing, resulting in low processing accuracy
