UK Premium Lighting Designer × Honscn High-Precision CNC-Machined Aluminum Connectors for Linear Lighting Systems

Product Overview: CNC Aluminum Connector Component

• Material: Aluminum 6061-T6

• Manufacturing Process: 3-axis and 4-axis CNC milling

• Surface Finish: Off-white powder coating

• Application: Linear lighting system connection and structural support

The component plays a critical role in aligning multiple optical modules and extruded aluminum profiles, ensuring seamless assembly and a refined final appearance.

Key Manufacturing Challenges

1. Ultra-Tight Tolerances for Seamless Assembly

To ensure perfect alignment with optical elements and extruded aluminum housings, the customer specified a fit tolerance of ±0.02 mm.

Maintaining this level of accuracy in aluminum machining required precise control of:

• Heat generation during cutting

• Machine stability

• Fixturing and repeatability

Any deviation could result in visible gaps or misalignment during installation.

2. Complex Internal Geometry

The internal structure of the connector included:

• Intersecting reinforcing ribs

• Dense threaded hole patterns

• Internal chamfers and side features

Conventional 3-axis machining alone could not complete all features in a single setup. Multiple re-clamping operations would have introduced cumulative errors, compromising dimensional accuracy.

3. High-End Surface Requirements for Visible Parts

The off-white powder coating chosen by the customer delivers a clean, modern aesthetic—but it also exposes even the smallest surface imperfections.

As a visible component, the part had to be:

• Free from tool marks and chatter

• Completely burr-free

• Uniform across all units

Any surface flaw would be amplified after coating and negatively affect the perceived product quality.

Our CNC Manufacturing Solution

4-Axis CNC Machining and Process Optimization

To achieve one-time forming of complex geometries, we utilized high-precision imported 4-axis CNC machines.

By leveraging the rotary axis for accurate positioning, we:

• Reduced the number of setups

• Eliminated tolerance stacking

• Maintained dimensional stability across all critical features

This approach ensured consistent accuracy throughout the production run.

High-Precision Cutting Tools for Superior Surface Finish

Based on the machining characteristics of 6061-T6 aluminum, we selected custom diamond-coated and high-polish finishing tools sourced from Japan and Germany.

These tools allowed us to:

• Achieve precise internal dimensions

• Produce smooth, near-mirror metal surfaces

• Create an ideal substrate for powder coating

The result was a flawless surface that required minimal post-processing.

Strict Quality Control and Measurement

Throughout production, key dimensions were monitored using Coordinate Measuring Machines (CMM).

This real-time inspection ensured that every batch of connectors met assembly requirements and allowed the customer to achieve repeatable, zero-adjustment installation.

Project Results & Delivery Performance

The final components exceeded customer expectations:

• Measured accuracy: ±0.015 mm

• Surface quality: Uniform off-white powder coating with no visible substrate marks

• Production efficiency: Machining cycle time reduced by 15% through 4-axis optimization

These improvements helped the customer accelerate their product launch while maintaining a premium brand image.
