CNC Milled Aluminum Plates

Detailed Description

CNC milled aluminum plates are precision-machined flat components designed for structural support, equipment mounting, fixture construction and mechanical assembly. Typical products include machine base plates, mounting panels, adapter plates, tooling plates and precision equipment platforms.

Common aluminum grades such as 6061-T6, 6082 and 7075 can be selected according to strength, weight, corrosion resistance and machining requirements. CNC milling allows pockets, slots, counterbores, threaded holes, locating holes and complex edge profiles to be machined into a single plate.

For assemblies requiring accurate positioning, critical hole patterns and datum surfaces can be controlled through multi-axis machining, probing and dimensional inspection. Surface treatments such as anodizing or hard anodizing can be added to improve corrosion resistance and surface durability.

Available Surface Finishes

• As-Machined: Visible machining marks with no additional surface treatment.
• Bead Blasting: Creates a uniform matte appearance.
• Clear Anodizing: Improves corrosion resistance while maintaining a metallic appearance.
• Black Anodizing: Provides a durable black technical finish.
• Hard Anodizing: Suitable for plates exposed to wear and repeated mechanical contact.
• Chemical Conversion Coating: Available for electrical and industrial applications.

Structural & Functional Breakdown

• Precision Hole Patterns: Drilled, reamed and threaded holes for accurate assembly.
• Pocketed Structure: Material can be removed to reduce weight while maintaining rigidity.
• Datum Surfaces: Controlled reference surfaces improve assembly positioning.
• Counterbore & Countersink Features: Allow fasteners to sit flush with the plate surface.
• Custom Edge Profiles: Chamfers, radii and contour machining support specialized installations.

Key Features

• High Dimensional Accuracy: Suitable for precision mechanical assemblies.
• Multiple Aluminum Grades: Supports 6061, 6082, 7075 and other machinable alloys.
• Complex Milling Capability: Pockets, slots, holes and threads can be combined in one component.
• Flatness Control: Machining strategies can be optimized for large plate components.
• Custom Thickness & Dimensions: Manufactured according to customer drawings.
• Prototype to Production: Suitable for prototypes, replacement parts and batch production.
