CNC turning of aluminum parts with a gray oxide surface

Product Overview

This precision aluminum part is manufactured through CNC numerical control turning technology and is coated with professional gray oxide surface treatment. It is specially designed for industrial and manufacturing applications that require high precision, durability, and an elegant appearance. The product boasts excellent dimensional stability and corrosion resistance, and is suitable for use in automated equipment, precision instruments, and customized projects.

Core feature

Precision turning process: Utilizing advanced CNC lathes for processing, ensuring a dimensional accuracy of ±0.01mm, meeting strict assembly requirements.

High-quality aluminum material: Lightweight yet with moderate strength, featuring excellent machinability and structural stability.

Gray oxide surface: Enhances surface hardness and wear resistance, forms a uniform matte gray protective layer, and increases corrosion resistance.

Process combination: After turning processing, direct oxidation treatment is carried out to ensure surface consistency and avoid secondary damage.

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.
