Precision Flange Cover Assembly

This disc-shaped component features a large central hole and evenly distributed threaded holes, typically serving as an end seal cap and connection flange for hydraulic, pneumatic systems, or fluid pipelines. The top surface exhibits a high-gloss mirror finish, while the sides retain multiple concentric turning marks. These visual characteristics indicate precise surface treatment and fine turning processes, designed to meet stringent assembly flatness requirements and aesthetic standards.

The core of machining this part lies in ensuring the flatness of the top mounting surface and the positional accuracy of the four threaded holes relative to the central hole. During manufacturing, high-precision CNC lathes or turn-mill composite centers are used for single-setup machining to eliminate cumulative errors from multiple clamping operations. This ensures that the coaxiality and perpendicularity of all holes strictly comply with drawing tolerances. The stepped transitions and rounded chamfers on the sides not only enhance structural strength but also prevent sharp edges, facilitating safer and easier subsequent assembly.
