Custom CNC Machined Aluminum Alloy Large Diameter Flange Disc Precision Milled Rotary Plate

Product Overview

This custom CNC machined large aluminum flange disc is processed by precision CNC turning and milling. It is a large round rotary plate with multi mounting holes and lightening cutouts. Made of aluminum alloy, it features lightweight, high rigidity and good heat dissipation. Strict control of flatness, concentricity and dimensional tolerance ensures stable rotary operation and accurate assembly. Widely used in rotary machinery, automation equipment, test platforms, transmission modules and aerospace related assemblies. OEM & ODM custom service is available based on your 2D/3D drawings or physical samples.

Key Features

1.    High Grade Aluminum Alloy Material Light weight, high structural rigidity, excellent thermal conductivity and oxidation resistance. Lightening cutouts reduce overall weight while maintaining structural strength.
2.    Precision CNC Turning & Milling Accurate hole positions, smooth machined surface without burrs. Tight tolerance control for flatness and concentricity to meet high-precision rotation requirements.
3.    Optimized Lightweight Round Structure Integrally machined large diameter disc with distributed mounting holes and lightening slots. Balanced design for stable high-speed rotation.
4.    Fully Customizable Specifications Outer diameter, central bore, hole layout, cutout shape and plate thickness can be customized according to your technical drawings.
5.    Multiple Surface Treatment Options Available with natural finish, sandblasting, anodizing, hard anodizing to enhance wear resistance and corrosion resistance.

FAQ

Q1: Can you produce this large aluminum flange disc according to my CAD drawings?

A: Yes, OEM & ODM are supported. Please send your 2D/3D drawings with tolerance requirements for quotation. Physical samples are also acceptable.

Q2: What aluminum alloys can you offer?

A: 6061 aluminum alloy is commonly used for general rotary components with good anodizing performance. 7075 aluminum alloy is available for projects requiring higher strength.

Q3: What is your MOQ?

A: MOQ is flexible. We accept prototype small batch orders as well as mass production orders. Please contact us for specific quotation.

Q4: Can you do anodizing or hard anodizing for this aluminum disc?

A: Sure. We can provide sandblasting, ordinary anodizing, hard anodizing and other surface treatments upon your request.

Q5: What is your normal production lead time?

A: Normally 10–20 working days for large diameter aluminum disc, depends on product complexity and order quantity. We will confirm the exact lead time before order confirmation.

Q6: What tolerance can you achieve for flatness and concentricity?

A: Standard machining tolerance ±0.02mm. Higher precision flatness and concentricity can be realized for high-precision rotary projects.

Q7: How do you control product quality?

A: We carry out full inspection for dimension, flatness and concentricity after CNC machining. Inspection reports can be provided if required.
