CNC Machined Black Multi-Hole Mounting Flange Base

As a critical transition component connecting pipelines to equipment bodies, this part features a central through-hole for media flow or shaft passage. Six evenly distributed countersunk mounting holes around the perimeter provide secure bolt locking force. This ring-shaped structure with lugs is commonly used in hydraulic system interfaces, pneumatic component bases, or sensor mounting brackets for automation equipment, requiring high concentricity and sealing capability after assembly.

The part surface presents a uniform matte black finish, likely achieved through anodizing or powder coating to enhance corrosion and wear resistance. Structurally, there is a distinct step between the outer flange and the inner hole, and the mounting lugs have sufficient thickness to withstand locking torque. This imposes high requirements on the consistency of multi-face clamping references during machining, ensuring that the positional tolerance of each mounting hole relative to the center hole is controlled within precise limits.

Leveraging our factory's existing 3-axis and 5-axis vertical CNC machining centers, we efficiently complete milling, drilling, and tapping processes for such disc-shaped parts. We strictly inspect hole distribution and flatness using fully automatic composite image measuring instruments. For such non-standard custom requirements, please provide 2D drawings including material specifications (e.g., aluminum alloy or stainless steel), surface treatment standards, and key dimensional tolerances to facilitate rapid feasibility assessment and quotation.
