Hydraulic Component Machining
Core Processing Services

Hydraulic Component Machining

Specializing in precision machining of hydraulic valve bodies, manifolds, and flow channel components with expertise in complex bore processing and high-precision mating surfaces.

Processing Capability

Years of deep expertise in the hydraulic industry, with extensive experience in hydraulic component manufacturing.

Complex channel machining

Precision machining of multi-channel internal flow passages in hydraulic valve bodies to ensure unobstructed fluid pathways.

Precision fit

The clearance between the valve core and the valve body should be controlled within 0.005-0.02 mm to ensure sealing performance.

Seal surface machining

Precision-machined sealing surfaces with surface roughness up to Ra0.4, meeting high-pressure sealing requirements.

Cleanliness Control

Strict cleanliness control during processing ensures no iron shavings remain inside the hydraulic system.
