CNC Machined Black Flange Connector

As a critical transition node in fluid control or mechanical transmission systems, this component, featuring a square mounting flange and a cylindrical journal, is primarily used to achieve rigid connections for pipelines, valve bodies, or actuators. One end is equipped with a standard four-hole flange plate, bolted to the equipment base to provide stable support; the other end extends into a cylindrical section with multi-directional threaded holes on the side, facilitating the connection of air or oil pipes, or radial locking of auxiliary components. It is commonly found in pneumatic circuits of automated production lines, hydraulic stations, or precision fixture connections.

The core of the manufacturing process lies in ensuring the perpendicularity of the flange mounting surface relative to the central axis, as well as precise control over the position of the side threaded holes, to prevent stress concentration or seal failure during assembly. Since the part involves multiple processes such as square head milling, outer circle turning, and deep hole tapping, it requires high-rigidity CNC machining centers and CNC lathes working in coordination, with a focus on monitoring coaxiality and positional tolerances between features. The surface undergoes black oxide or powder coating treatment, which not only enhances aesthetic quality but also improves corrosion and wear resistance in industrial environments.
