High Accuracy ±0.01mm for Semiconductor, Medical & Industrial Automation

Precision symmetrical aluminum fixture, 5-axis CNC machined from 6061-T6 aluminum. High accuracy ±0.01mm, custom surface treatments (anodizing, nickel plating) for semiconductor, medical, and automation industries.

Material: 6061-T6 Aluminum Alloy

Key Advantages:

Low density, moderate strength, and minimal post-machining deformation

Excellent machinability for high-speed precision cutting

Enhanced wear and corrosion resistance after anodization

Superior thermal conductivity to dissipate heat and prevent thermal distortion

Surface Treatment Options

Treatment	Benefits & Aesthetics	Ideal Use Case
Clear Anodizing	5–20μm protective film, retains metallic appearance, improves wear resistance	General-purpose precision fixtures
Hard Anodizing	HV300–500 hardness, exceptional durability for high-load applications	Heavy-use industrial clamping
Bead Blasting + Anodizing	Matte, non-reflective finish with enhanced visual appeal	High-end equipment and medical devices
Electroless Nickel Plating	High hardness, corrosion resistance, and non-magnetic properties	Electronic and semiconductor components

Machining Process

Primary Technology: 5-axis CNC Machining Center

Auxiliary Processes: Surface grinding, jig boring, deburring, and ultrasonic cleaning

Rough Machining: Remove excess material, leaving a 0.5–1mm allowance for finishing

Semi-Finishing: Machine primary locating surfaces and mounting holes to establish geometric tolerances

Finishing: Complete multi-surface machining in a single setup to ensure dimensional accuracy and surface finish

Stress Relief: Low-temperature aging to eliminate internal machining stresses

Deburring & Cleaning: Remove sharp edges and contaminants for a clean, precision-ready surface

Difficulty Level: Medium-High (precision symmetrical structure)

Key Challenges:

Strict left-right symmetry control (≤0.01mm)

Tight coaxiality and positional tolerances for multiple mounting/locating holes

Thin-wall structure prone to deformation, requiring optimized fixturing and cutting parameters

Precision Specifications:

Dimensional tolerance: ±0.01mm

Geometric tolerance: Flatness 0.005mm, parallelism 0.01mm

Surface roughness: Ra 0.8–1.6μm (critical locating surfaces: Ra 0.4μm)
