CNC Custom Aluminum Parts Precision Milling Anodizing

Product Overview

This product is a high-precision CNC machine-cut aluminum part. It is formed in one step through CNC milling technology, featuring a symmetrical structure and smooth contours. It combines functionality with industrial aesthetics, and is suitable for various application scenarios such as the enclosures of automated equipment, mechanical structural components, guiding and installation parts, etc. The product design focuses on assembly stability and space utilization, making it suitable for overseas OEM/ODM customers who have high requirements for dimensional consistency and appearance quality.

After processing, the surface of the part undergoes 120-mesh sandblasting treatment, which effectively eliminates the machining marks and gives the surface a uniform and fine matte texture. Then, a black hard anodizing treatment is carried out with a film thickness of 25–40 μm. This significantly enhances the product's wear resistance, corrosion resistance and oxidation resistance, making it suitable for long-term operation or complex industrial environments. The hard anodizing layer has strong adhesion, is not prone to peeling off, and also has good appearance consistency.

In terms of materials, 6061, 6063, 7075 and other aluminum alloys can be selected according to customer requirements, taking into account strength, weight and processing performance. The key dimensions can be strictly controlled according to the drawings, with a tolerance of ±0.01mm, meeting the requirements for precise assembly and functional verification.

Minimum order quantity (MOQ) is 1 piece (1 PCS). This is ideal for sample production, small batch trial production and project verification stages. The delivery time is flexible and usually within 5-25 days. We can provide surface treatment, structural optimization and process suggestions based on customer needs, helping buyers reduce overall procurement and trial-and-error costs. It is a reliable choice for CNC customized processing cooperation.

We are proud to hold several production certificates for our CNC machining services,which demonstrates our commitment to quality and customer satisfaction.

1、ISO13485:MEDICAL DEVICES QUALITYMANAGEMENT SYSTEM CERTIFICATE

2、ISO9001:QUALITY MANAGEMENT SYSTEMCERTIFICATE

3、IATF16949、AS9100、SGS、CE、CQC、RoHS

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.
