Precision CNC milling of aluminum parts

Product Overview

Core advantage

This product is manufactured using high-precision CNC milling technology, which directly converts aluminum alloy sheets into complex three-dimensional structural components. Compared to traditional processing methods, it can precisely form multiple surfaces, curved surfaces, slots, holes, and threads in one setup, ensuring that the components have excellent geometric consistency and assembly compatibility.

Highlights of Technology and Materials

Multi-axis CNC milling technology: Utilizing high-performance machining centers, we achieve integrated precision processing of the front, side, and inclined surfaces, with the minimum detail accuracy reaching ±0.02mm.

High-quality aluminum base material: Utilizes 6061 or 7075 series aluminum, achieving a balance between strength, lightweight, and machining performance, without internal stress concentration.

Smooth processing surface: Optimized tool path and cutting parameters ensure a fine and uniform surface finish. This surface can be directly used for assembly or further surface treatment.

Flexible adaptive design: Particularly suitable for processing parts with irregular contours, stepped structures, deep cavities or thin-walled features.

Technical Specifications

Processing range: Maximum 300mm × 200mm × 150mm (customizable)

Standard tolerance: ±0.02mm (Negotiable at the fine feature locations)

Surface roughness: Ra ≤ 3.2 μm (after milling)

Delivery form: Provide standard deburring and sharp edge chamfering treatment

Quality Control

The entire process adopts a digital processing flow, equipped with a three-coordinate measuring instrument and a projector for key dimension inspection, ensuring that each batch of parts complies with the drawing specifications.

Customized Support

Q:How fast can I receive a CNC prototype?

A:Lead times vary depending on part complexity, material availability, and finishing requirements, but generally:

• Simple prototypes: 1–3 business days

• Complex or multi-part projects: 5–10 business days

Expedited service is often available.

Q:What design files do I need to provide?

A：To get started, you should submit:

• 3D CAD files (preferably in STEP, IGES, or STL format)

• 2D drawings (PDF or DWG) if specific tolerances, threads, or surface finishes are required

Q:Can you handle tight tolerances?

A:Yes. CNC machining is ideal for achieving tight tolerances, typically within:

• ±0.005" (±0.127 mm) standard

• Tighter tolerances available upon request (e.g., ±0.001" or better)

Q:Is CNC prototyping suitable for functional testing?

A:Yes. CNC prototypes are made from real engineering-grade materials, making them ideal for functional testing, fit checks, and mechanical evaluations.

Q:Do you offer low-volume production in addition to prototypes?

A:Yes. Many CNC services provide bridge production or low-volume manufacturing, ideal for quantities from 1 to several hundred units.

Q:Is my design confidential?

A:Yes. Reputable CNC prototype services always sign Non-Disclosure Agreements (NDAs) and treat your files and intellectual property with full confidentiality.
