Precision CNC Turning Aluminum with Bright Black Oxidation

Product Overview

This high-precision aluminum component is made of high-quality aluminum and is precisely manufactured through advanced CNC processing technology. It is specially designed for industrial equipment, precision instruments and high-end mechanical components. The product has a simple and elegant appearance, with precise dimensions, ensuring excellent stability and reliability during assembly and use.

In terms of processing technology, this part was machined by CNC turning, achieving high-precision shaping of cylindrical shapes and complex internal holes, and ensuring that the dimensional tolerance is strictly controlled within ±0.01 millimeters. The surface was treated with bright black anodizing, with the surface roughness controlled between Ra0.8μm and Ra1.6μm. This not only enhances the surface smoothness and touch feel, but also provides excellent wear resistance and corrosion resistance, thereby extending the service life of the part.

This part is applicable to a variety of high-precision applications, such as mechanical connection shafts, positioning pins, and fastening support components, etc. The bright black oxidation treatment not only offers excellent protective functions but also gives the part a high-end metallic texture, meeting the dual requirements of industrial aesthetics and functionality.

Whether it is for single-piece customization, prototype trial production, or small-batch mass production, this CNC aluminum part can provide stable dimensional accuracy and excellent surface performance, helping customers improve product assembly accuracy and overall mechanical performance. It is an ideal choice for engineering projects that aim for high precision and high reliability.

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.
