Detailed Description

When machining the valve block, the form and position tolerance must be strictly controlled to meet the use requirements. The reference value of form and position tolerance is as follows: the perpendicularity tolerance between the six surfaces of the valve block is 0.05mm; The parallelism tolerance of the opposite surface is 0.03mm; The flatness tolerance of each surface is 0.02mm; The perpendicularity tolerance between the thread and its mating surface is 0.05mm; The tolerance of perpendicularity between all holes and the end face is 0.05mm. In order to ensure the cleanliness of the hydraulic system, the hydraulic valve block must be deburred. At present, many manufacturers still use brush for manual deburring, but also use methane blasting method for deburring. After deburring the hydraulic valve block, it needs to pass the inspection of industrial endoscope to ensure that the deburring is completed.
