Custom CNC Machined Flange

Product Overview

Our custom CNC machined flange is produced for machinery systems, industrial assemblies, and OEM equipment applications requiring secure connection, dimensional accuracy, and stable structural performance. As a professional CNC machined flange manufacturer and flange machining supplier, we utilize precision CNC machining to ensure accurate hole positions, flatness, and reliable fitting quality for every industrial flange.

We can manufacture flanges in stainless steel, aluminum, brass, and carbon steel according to customer drawings, outer diameter requirements, hole patterns, and thickness specifications. This allows the custom flange to meet different mechanical and assembly needs. As an experienced OEM flange machining provider, we support prototypes and volume production for global B2B buyers.

Technical Specifications

Materials and Manufacturing Process

This CNC machined flange is produced by turning, milling, drilling, and finishing according to drawing requirements. As a professional custom flange manufacturer, we operate advanced CNC machining centers and lathes to deliver consistent quality for every precision CNC flange order.

Material options include:

• Stainless Steel Flange – SS304 / SS316 for excellent corrosion resistance in harsh environments

• Aluminum Flange – 6061-T6 / 6063 / 7075 for lightweight applications with good strength

• Brass Flange – H59 / H62 / C3604 for decorative and electrical conductivity applications

• Carbon Steel Flange – high strength and durability for heavy-duty industrial machinery

Available surface treatments include:

• Polishing – smooth, reflective surface for aesthetic and functional applications

• Zinc Plating – enhanced corrosion protection for carbon steel flanges

• Anodizing – hard, protective coating for aluminum flanges with color options

• Passivation – chemical treatment to maximize stainless steel corrosion resistance

Applications

Our precision CNC machined flanges are widely used in:

• Machinery Systems – pump housings, motor mounts, gearbox connections, and bearing supports

• Industrial Assemblies – pipe connections, structural joints, and equipment mounting plates

• Equipment Structures – frame connections, support brackets, and load distribution components

• Connection Components – bolted joints, clamping interfaces, and alignment fixtures

• OEM Projects – custom machinery, prototypes, replacement parts, and specialized equipment

• Automotive and Transportation – exhaust systems, suspension components, and engine assemblies

Custom Manufacturing Support

We support custom flange production based on diameter, thickness, hole layout, material selection, and finishing requirements. Our engineering team reviews your drawings and specifications to develop optimal manufacturing solutions for every OEM flange machining project.

Custom capabilities include:

• Drawing-Based Production – manufacturing from CAD files, PDFs, or physical samples

• Custom Dimensions – outer diameter, inner diameter, thickness, and overall profile

• Hole Patterns – bolt circle diameter, number of holes, hole diameter, tapped threads, counterbores

• Material Selection – stainless steel, aluminum, brass, carbon steel, or custom alloys

• Surface Treatment – polishing, zinc plating, anodizing, passivation, or custom finishes

• Quality Documentation – inspection reports, material certificates, and dimensional verification
