Detailed description

Custom CNC Turned Hollow Housing with Blue Anodizing

Our Custom CNC Turned Hollow Housing with Blue Anodizing is a precision curved hollow aluminum casing manufactured by multi-axis CNC turning. As a professional CNC machining manufacturer in Dongguan, we produce irregular contour hollow housings with smooth curved surfaces and customizable dimensions. Blue matte anodizing provides excellent wear resistance and decorative appearance. These housings are widely used as outer casings for consumer electronics, handheld devices, instrument equipment and mechanical decorative parts. We accept drawing-based OEM customization with flexible color and structural adjustment.

Introduction to CNC Lathe Turning Technology

CNC lathe turning is one of the most precise and efficient manufacturing methods for rotational metal components used in industrial automation and precision equipment. Using programmable multi-axis turning centers, solid metal bars are shaped through continuous cutting, facing, grooving, threading and boring operations with computer-controlled accuracy.
Compared with manual machining and traditional milling, precision CNC turning delivers consistent dimensional tolerances down to ±0.01mm, smooth surface finishes and excellent repeatability across high-volume production runs. It is widely used to produce pins, shafts, bushings, connectors and threaded components for mold tooling, electronic devices, medical equipment, automotive systems and industrial automation machinery.
With advanced multi-axis turning capabilities and secondary milling support, CNC lathe technology supports custom geometries including stepped diameters, ball heads, hex bodies and precision slots, which perfectly meets the diversified demands of precision locating components for industrial equipment.

What Is CNC Turned Hollow Housing & Its Industrial Role

CNC turned hollow housing is a tubular hollow enclosure formed by turning processing, which can be designed with symmetrical curved contours such as hourglass shape. It acts as a protective outer shell for internal components and takes into account structural performance and aesthetic appearance at the same time.
Common flat machined housings cannot achieve seamless smooth curved surfaces. Multi-axis CNC turning realizes continuous arc profiling, ensuring uniform wall thickness and streamline appearance. After anodizing treatment, aluminum housing obtains scratch-resistant, anti-corrosion colored surface, which is ideal for consumer electronics, portable instruments and customized hardware accessories.

Custom Hollow Housing with Blue Anodizing – Precision CNC Turning Service

We provide one-stop CNC turning customization service for hollow housings. Besides hourglass curved housings, we process straight tubular housings, tapered hollow shells, stepped hollow enclosures and other rotary-shaped casings.
All parts are processed by multi-axis CNC lathes to guarantee smooth arc transition and stable wall thickness. We complete turning, deburring and surface anodizing in-house. Customers can choose different anodizing colors, surface roughness and wall thickness according to assembly requirements. We support small batch prototype sampling and continuous mass production.

Key Advantages of Our CNC Turned Hollow Housing

Smooth seamless curved contour machining

Multi-axis turning realizes continuous arc forming without obvious splicing traces, uniform surface texture for high-grade appearance requirements.

Rich optional anodized colors

Supports blue, black, silver, red, champagne gold and other anodizing options; matte or glossy surface available to meet different design styles.

Highly stable dimensional accuracy

Strictly controlled ±0.01mm tolerance, consistent wall thickness, effectively avoiding deformation during assembly and usage.

Lightweight and durable aluminum options

6061/7075 aluminum alloy features low weight, good machinability. Anodized layer enhances hardness, scratch resistance and anti-corrosion performance.

Flexible drawing-based customization

We modify shape, size, inner cavity structure and openings strictly according to your engineering drawings or physical samples.

Frequently Asked Questions

FAQ 1

Q: Can you produce custom CNC turned parts according to my drawings or samples?
A: Yes, we mainly focus on OEM & ODM customized precision turning services. We accept 2D files like PDF/DWG and 3D files such as STEP, IGES. You can also send physical samples for us to reverse-engineer and optimize the structure. Our engineering team will review your design and offer professional suggestions on cost saving and manufacturability (DFM) for free.

FAQ 2

Q: What kinds of metal materials can you use for CNC turning processing?
A: We support a full range of common precision machining metals, including SUS304/SUS316 stainless steel, 1018/1045 carbon steel, 6061/7075 aluminum alloy, C36000 brass, copper and titanium. We can select suitable raw materials based on your product usage, working environment, strength requirements and budget.

FAQ 3

Q: Can I get trial samples before mass production? How long is the sample lead time?
A: Trial samples are available for all customized turning orders. The sample production cycle is 3–7 working days after drawing confirmation. After you test and confirm the sample quality and dimensions, we will arrange mass production. Small batch trial orders are also acceptable if you do not need large volume at first.

FAQ 4

Q: What surface finishing options do you provide for CNC turned metal parts?
A: We offer multiple surface treatments to meet anti-rust, anti-corrosion, wear resistance and appearance demands: passivation, electropolishing, zinc plating, nickel plating, black oxide, powder coating, anodizing for aluminum, sandblasting and polishing. If your products are exported to Europe, we can provide surface treatment that complies with RoHS and REACH standards.

FAQ 5

Q: How do you control the dimensional tolerance of precision CNC turned parts?
A: Our standard tolerance for general turned parts is ±0.01mm, and ultra-precision components can achieve ±0.005mm with grinding processes. We carry out strict three-step quality inspection: IQC for raw material incoming check, IPQC for in-process production monitoring, and FQC full dimension testing before shipment. We provide inspection reports and accept third-party quality inspection as requested.
