Deburring and heat treatment residue removal of hydraulic valve block. Another major problem of auxiliary processing of hydraulic valve block is deburring and heat treatment residue removal. The existence of burr will cause adverse effects on hydraulic parts, such as stem clamping and damping hole blocking. It is grinding in the balance groove of chromium plated stem. Burr moves into the gap between stem and valve hole with the action of oil radial hydrodynamic force, which can not eliminate the hydrodynamic force, but will lead to stem clamping, increased operating force or unstable system pressure, The fretting performance and pressure modulation performance decrease.
