In the field of precision manufacturing, metal housing parts for optical applications are widely used in optical instruments, medical devices, and communication systems. These components require exceptionally high standards for surface quality, dimensional accuracy, and tight tolerance control. With the maturation of Malaysia 5 Axis CNC Machining technology, Malaysia has increasingly become a top destination for international clients seeking low-cost, high-precision CNC machining services (Malaysia Low Cost CNC Machining).

1. Requirements for Optical Metal Housing Parts

Metal housing parts for optical applications are typically made from stainless steel, aluminum alloys, or titanium, and must meet the following requirements:

  • Scratch-free and deformation-free surfaces

  • Tight tolerances within ±0.005mm to ±0.01mm

  • High concentricity and perpendicularity

  • Excellent corrosion resistance and thermal stability

2. Advantages of 5 Axis CNC Machining

Traditional 3-axis machining cannot meet the demands of complex multi-surface geometries. In this context, 5 Axis CNC Machining in Malaysia emerges as a key solution for complex structural parts. Combined with local engineering talent and lower operating costs, Malaysia offers several core advantages:

Advantage Description
One-time setup from multiple angles Reduces clamping times, improves precision
High efficiency & repeatability More cost-effective for batch production
Excellent for complex contours Ideal for optical housings and aerospace parts
Strong inspection capability Equipped with CMMs, optical measurement tools, etc.


3. CNC Materials and Tolerance Capabilities

In metalworking, different materials require tailored machining strategies. Here are some commonly used materials and their machining characteristics from our case studies:

Material Type Application Machining Difficulty Recommended Process
CNC Stainless Steel (e.g., SUS304, SUS316) Medical instruments, optical bases High Low-speed, rigid tooling
Aluminum Alloys (Al6061, Al7075) Camera housings, heat sinks Medium CNC Turning + Anodizing
Titanium Alloys (Ti6Al4V) High-end optical housings High 5 Axis machining + titanium tools

Tolerance control we offer:

  • Roundness / Concentricity: ≤0.01mm

  • Straightness / Perpendicularity: ≤0.02mm

  • Thread Accuracy: Class 6H

  • Surface Roughness: Ra 0.4μm to Ra 1.6μm

4. Professional CNC Machining Process Control

A complete CNC machining process from raw material selection to final surface finish is tightly controlled to ensure product stability and consistent quality:

  1. Design Review (DFM analysis + process planning)

  2. CAM Programming & Strategy Definition (optimized toolpaths, avoidance planning, sequence breakdown)

  3. 5 Axis / 3 Axis CNC Machining (Turning, Milling, Drilling included)

  4. Surface Treatment (Anodizing, Plating, Sandblasting)

  5. Inspection Process (CMM, Roughness tester, Optical comparator)
