High-Strength Carbon Steel Coupling | Industrial Hydraulic System Solutions

European-style hydraulic fittings serve as connection interfaces in hydraulic systems, ensuring reliable flow of high-pressure hydraulic fluid. Widely used in machine tools, industrial machinery, and agricultural equipment requiring precise hydraulic control.

The manufacturing challenge of hydraulic connectors lies in maintaining dimensional accuracy and sealing reliability throughout mass production. This product presents three major process challenges:
First, turning accuracy for eccentric geometric features. The main body and radial offset section must be machined in a single setup to eliminate runout caused by re-fixturing. This demands both machine rigidity and sophisticated toolpath programming.
Second, control of multiple geometric tolerances. From threaded sections to sealing surfaces, each mating interface requires strict positional and perpendicularity tolerances, necessitating precision measurement equipment and real-time process monitoring.
Third, dimensional stability after heat treatment. When medium carbon steel undergoes quenching and tempering to achieve specified hardness, critical dimensions are susceptible to distortion. This requires either machining allowances for distortion compensation or post-heat-treatment finishing operations.
Our turn-mill machining capabilities enable complex geometry production. Combined with SPC process control and long-standing collaboration with heat treatment partners, we consistently deliver these high-precision hydraulic components.
