Custom Shafts, Bushings & Complex Round Parts

What is CNC Turning?

CNC turning is a subtractive manufacturing process where a cutting tool moves linearly while the workpiece rotates, creating cylindrical or contoured parts.

At Hengshuo Precision, we offer high-precision CNC turning for aluminum, steel, stainless steel, brass, and engineering plastics. From simple shafts to complex parts with live tooling, we ensure accuracy and fast lead times.

Materials We Machine

1. High-Precision CNC Turning

Precision CNC-turned copper parts, made from high-purity copper for excellent thermal and electrical conductivity. With mirror-finished internal surfaces and tight dimensional tolerances, these components are ideal for heat sinks, electrodes, vacuum system parts, and high-performance industrial applications.

2. Aluminum CNC Machined Heat Sink / Connector

These precision aluminum components are manufactured using combined CNC turning and milling processes. Turning creates the cylindrical body and ring-shaped fins for efficient heat dissipation, while milling produces the end slots and mounting holes. Made from lightweight, high-conductivity aluminum alloy, they offer excellent thermal performance, corrosion resistance, and dimensional stability, ideal for automation equipment, motor assemblies, and industrial cooling applications.

3. Stainless Steel CNC Turned Shaft & Connector

Precision CNC-turned stainless steel shaft components, featuring stepped diameters, flanges, and integrated ring features. Machined from high-grade stainless steel for excellent strength, corrosion resistance, and dimensional stability. With mirror-finished surfaces and tight tolerances, these parts are ideal for industrial equipment, fluid systems, and mechanical assemblies requiring 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.
