CNC Milling Services

Precision 3-Axis to 5-Axis CNC Milling for Custom Parts & Prototypes

What is CNC Milling?

CNC milling is a precision subtractive manufacturing process that uses computer-controlled tools to create custom parts from solid materials.

At Hengshuo Precision, we offer high-quality CNC milling services for aluminum, steel, and plastics, with tight tolerances down to ±0.005mm. From prototypes to mass production, we ensure accuracy and on-time delivery for your projects.

Materials We Machine

1. High-Quality Brass Machining

Our brass CNC machining delivers parts with exceptional machinability, thermal conductivity, and rust resistance. From complex geometries to simple fittings, we ensure consistent precision, clean edges, and a premium finish that meets industrial, commercial, and decorative requirements.

2. Aluminum CNC Machined Components

Precision CNC milled aluminum parts, such as this custom adjustment plate, are crafted from high-grade aluminum alloy. Lightweight yet strong, with excellent machinability and corrosion resistance, they feature tight tolerance holes, precision slots, and smooth finishes. Ideal for automation equipment, aerospace, and consumer electronics applications.

3. Stainless Steel CNC Machined Fittings

These precision stainless steel elbow fittings are manufactured using combined CNC turning and milling processes. Turning creates the threaded ends and cylindrical features, while milling forms the 90° body structure. Designed for fluid connections, sensor housings, and mechanical assemblies, they deliver excellent corrosion resistance, tight tolerances, and reliable performance in demanding environments.

4. PEEK / Engineering Plastic Machined Fittings

These precision CNC-turned plastic fittings are made from high-performance engineering plastics such as PEEK, POM, or ABS. With excellent chemical resistance, low friction, and dimensional stability, they feature tight tolerance bores and internal threads, making them ideal for fluid systems, medical equipment, and semiconductor applications. Lightweight and corrosion-free, they offer a reliable alternative to metal components in demanding environments.
