High-precision semi-hard copper-made CNC processed parts

Product Overview

Our semi-hard copper CNC machined parts are precisely manufactured using advanced CNC turning technology, and are suitable for various high-demand industrial applications. Each part undergoes strict quality control to ensure a tolerance of ±0.01 millimeters, guaranteeing excellent precision and performance.

Processing techniques and surface treatment

This product adopts the turning process. Firstly, the basic shape is precisely processed. Then, it undergoes anodic oxidation treatment, which enhances the surface corrosion resistance and aesthetic appeal. The surface color after anodic oxidation treatment is uniform, durable, and suitable for use in harsh environments. Furthermore, the surface of the parts has also been polished, presenting a smooth and shiny surface effect, which greatly improves the appearance quality of the product.

To enhance the protective capability of the product, a three-layer electroplating process was carried out on the surface: copper plating, nickel plating and chromium plating. This series of surface treatments not only increased the corrosion resistance of the parts, but also enhanced their wear resistance and prolonged their service life. The copper plating layer provides excellent conductivity, the nickel plating layer enhances corrosion resistance, and the chromium plating layer effectively improves the antioxidant capacity and surface hardness of the parts.

Application Areas and Advantages

These high-precision semi-hard copper parts are widely used in the fields of electronics, automobiles, machinery and other industries. Their precise processing technology and high-quality surface treatment enable them to perform exceptionally well in demanding applications. Whether it is a need for high conductivity or a requirement for surface wear resistance, this product can meet the needs of customers.

The CNC machining services we offer can customize the size and processing method of each part according to the specific requirements of the customers, ensuring a perfect match with their technical specifications. Whether it is single-piece or small-batch production or large-scale demand, we can provide a fast delivery period to ensure that customers can obtain the required products in a timely manner.

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.
