Aerospace Aluminum Bracket CNC Machining
Control Focus:
ZH Precision ensures precise hole positions, surface flatness, and edge straightness for aerospace aluminum brackets. Strict tolerances on mounting surfaces and bolt patterns guarantee seamless assembly, structural integrity, and optimal load distribution in critical aerospace components.
Process Technology:
We utilize CNC milling and turning to produce the brackets with high precision. Key surfaces are machined first to establish datum references, followed by multi-axis milling for angled features and slots. All operations maintain a single coordinate system, ensuring consistent tolerances, minimal residual stress, and superior part performance under operational loads.
Custom Aluminum Gear Housing CNC Machining
Control Focus:
ZH Precision maintains tight control over bore concentricity, wall thickness uniformity, and assembly interfaces in custom aluminum gear housings. This ensures optimal gear alignment, smooth rotational motion, and long-term durability under high-torque conditions.
Process Technology:
The housings are machined using a combination of CNC turning and 5-axis milling. Boresholes are finished first with precise tolerances, then the outer contours and mounting features are milled in a single coordinate setup. This approach guarantees dimensional accuracy, consistent surface finish, and reliable performance for both prototyping and small-batch production.

Surface Finishing for CNC Machined Parts
ZH Precision provides tailored surface finishing for CNC machined parts, including anodizing, powder coating, plating, and polishing. All finishes are inspected for consistent quality and durability, ensuring both functional performance and aesthetic appeal.
As Machined
As machined finish leaves the surface straight from the CNC machine, providing a cost-effective option with tool marks.
Anodizing
Enhances corrosion resistance and surface hardness while adding color for improved durability and appearance.
Polishing
Polishing achieves a high gloss finish, reducing surface roughness and enhancing the aesthetic appeal of metals.
Sand Blasting
Sand blasting uses pressurized sand or other media to clean and texture the surface, creating a uniform, matte finish.
Tumbling
Tumbling smooths and polishes small parts by friction and abrasion in a barrel, offering a consistent but slightly textured finish.
Electropolish
Electropolish is a chemical process that smooths and brightens surfaces while improving corrosion resistance.
Alodine
Alodine coating provides corrosion protection and improves paint adhesion, mainly used on aluminum surfaces.
Electroplating
Electroplating bonds a thin metal layer onto parts, improving wear resistance, corrosion resistance, and surface conductivity.
What is aluminum CNC machining?
Aluminum CNC machining is a precision manufacturing process that uses computer-controlled tools to cut, shape, and finish aluminum parts according to exact specifications. CNC, or Computer Numerical Control, allows for highly accurate milling, turning, and multi-axis machining, making it possible to create complex geometries, tight tolerances, and consistent parts. This process is widely used for prototypes, low-volume production, and full-scale manufacturing in industries such as aerospace, automotive, electronics, and industrial equipment. Aluminum is especially suited for CNC machining due to its lightweight, strength, corrosion resistance, and excellent machinability, allowing for efficient production of both functional and aesthetic components.
Advantages of Aluminum CNC Machining
Lightweight: Aluminum has a low density of about 2.7 g/cm³, making it ideal for applications where weight reduction is critical, such as aerospace and automotive components.
Corrosion Resistance: Aluminum naturally resists corrosion, and combined with coatings or anodizing, ensures durable and long-lasting CNC parts.
Excellent Conductivity: Aluminum conducts heat and electricity efficiently, suitable for components requiring thermal or electrical performance.
High Machinability: Aluminum is easy to machine, drill, and shape, allowing for complex geometries and precise features.
Temperature Stability: Aluminum maintains its mechanical properties over a wide temperature range, providing flexibility in machining and end-use applications.
Cons of Aluminum CNC Machining
Lower Hardness: Pure aluminum is relatively soft, which can cause wear on tooling and reduce part durability, so alloys are often preferred.
Higher Material Cost: Aluminum requires extraction and processing from bauxite, making it more expensive than some other industrial materials.
Susceptible to Scratches and Dings: Aluminum’s softer surface can scratch or dent easily, especially on polished or glossy finishes.
Thermal Expansion: Aluminum expands more than steel at high temperatures, which can affect dimensional stability in precision assemblies.
Limited Load-Bearing Strength: Compared to steel or titanium, aluminum has lower yield strength, which may limit its use in heavy-load structural components.
