Custom CNC Machined Flanges | Precision Metal Rings

Custom CNC Precision Flange Rings and Metal Parts with Black Surface Finish

Product Overview

Hongsinn Precision provides custom CNC machining services for precision flange rings, ring-shaped connectors, and complex metal structural components. The product shown features a circular main body with a central through-hole, stepped inner and outer diameters, and multiple sets of circumferentially arranged mounting and threaded holes. Hole layouts, fit dimensions, and connection configurations can be tailored to meet specific equipment design requirements.

These precision flange components are typically used for connecting, positioning, securing, and assembling mechanical components. Through processes such as CNC turning, CNC milling, drilling, tapping, and precision boring, we ensure strict adherence to customer specifications regarding hole positional accuracy, surface flatness, concentricity, and assembly fit.

The parts feature a black metallic finish; the specific surface treatment process can be selected based on the material used and the intended operating environment. Hongsinn Precision offers OEM/ODM services, manufacturing parts according to client drawings. We provide comprehensive precision machining solutions—from prototype development to mass production—for overseas equipment manufacturers, industrial component procurers, and mechanical engineering firms.

Technical Specifications

Product Features

1. Multi-Hole Flange Design

Mounting holes, threaded holes, and locating holes can be arranged on the inner and outer rings of the flange according to engineering drawings, facilitating bolted connections and structural assembly with mating components.

2. Precision Annular Machining

Features such as central through-holes, internal steps, annular grooves, and mating surfaces can be machined to specifications, meeting the positioning and assembly requirements of various components.

3. Precision CNC Machining

Processes including CNC turning, CNC milling, drilling, tapping, and other relevant techniques are employed based on the part's geometry to ensure precise control over critical dimensions and hole positioning.

4. Optional Black Surface Finishes

Depending on the base material, required wear and corrosion resistance, aesthetic preferences, and the operating environment, options such as black oxide, chemical blackening, black anodizing, or other suitable surface treatments can be applied. The specific process must be determined in conjunction with the material type; selection cannot be based on color alone.

5. OEM/ODM Customization

Custom production is available based on 2D engineering drawings, 3D CAD models, or physical samples. Parameters such as outer diameter, inner diameter, thickness, step height, hole configuration, and thread specifications can be tailored to your requirements.
