CNC Machined Aluminum Flange Adapter

Dimensional drawings are required to define the precise bore diameter, flange thickness, and thread specifications for these circular adapter plates. The parts feature a robust cylindrical body with a central through-hole and a perimeter ring of threaded mounting points, designed to interface with rotating shafts or secure mechanical sub-assemblies in automated equipment.

Machining these components demands strict concentricity between the central axis and the outer mounting pattern to prevent vibration during operation. The visible side features counterbored or countersunk holes arranged in a uniform circle, requiring accurate positional tolerance to ensure seamless alignment with mating fixtures. Surface finish on the face and OD is critical for aesthetic consistency and proper fit within tight enclosures.

Our Shenzhen facility utilizes high-precision CNC machining centers from brands like Beijing Jingdiao and Mazak to achieve the tight tolerances necessary for these structural interfaces. We support materials including aluminum alloys and stainless steel, offering secondary processes such as anodizing or passivation to enhance corrosion resistance. Quality verification is conducted using Hexagon and Zeiss CMMs to validate hole patterns and flatness before shipment.

Cost and lead time estimates depend on the specified material grade, batch volume, and any special surface treatment requirements. Please provide STEP files or PDF drawings indicating key datums and tolerance bands so we can align our programming strategy with your assembly needs. We accommodate both low-volume prototyping and higher-volume production runs for industrial machinery and semiconductor equipment sectors.
