CNC Milling

For aluminum housings, brackets, plates, fixtures, heat sinks, pockets, and other prismatic components with machined surfaces and controlled features.

CNC Turning

For spacers, sleeves, shafts, threaded fittings, bushings, and other round parts with controlled OD, ID, threads, and concentric features.

5-Axis Aluminum Machining

For complex aluminum parts with features on multiple faces, angled holes, deep pockets, or critical datum relationships that benefit from fewer setups.

Common part types:
Aluminum housings · Electronic enclosures · Brackets · Heat sinks · Fixture plates · Mounting plates · Manifolds · Sensor housings · Robotic components · Spacers · Sleeves · Threaded fittings

Which Aluminum Alloy Should You Choose?

The right alloy depends on strength, weight, corrosion exposure, finishing requirements, cost, and part function.

Alloy	Typical Applications	What to Consider
6061	Housings · Brackets · Fixtures · Plates	Balanced machinability, strength, corrosion resistance, and anodizing compatibility
7075	High-strength brackets · Robotics · Structural parts	Higher strength where weight matters; finishing and corrosion protection should be reviewed
6063	Heat sinks · Appearance parts · Extrusion-related components	Useful where thermal performance or anodized appearance matters
2024	Strength- and fatigue-critical components	Good mechanical performance; corrosion protection requires more attention

What We Review Before Machining Aluminum Parts

Aluminum machines efficiently, but geometry, clamping, tolerances, and finishing can still affect part quality and cost.

Thin Walls

Thin housings and deep pockets are reviewed for wall thickness, clamping strategy, tool access, internal radii, and deformation risk.

Tolerances & Datums

Critical dimensions, mating features, flatness, and positional relationships should be identified on the drawing.

Threads

Thread depth, engagement, inserts, and repeated assembly requirements can be reviewed before machining.

Deep Pockets & Internal Corners

Practical corner radii and tool access can reduce machining time, tool deflection, and unnecessary cost.

Cosmetic Surfaces

Visible surfaces should be identified so machining marks, bead blasting, anodizing, masking, and packaging can be planned together.

Anodizing & Surface Finishing

Finishing should be considered before machining because it can affect appearance, edges, threads, fits, and critical dimensions.

As-Machined

For functional parts where machining marks are acceptable.

Bead Blasting

Creates a more uniform matte surface and is commonly used before anodizing.

Clear & Black Anodizing

For corrosion protection and customer-facing housings, brackets, and hardware.

Hard Anodizing

For parts requiring greater wear and surface protection.

Other Finishes

Powder coating, painting, plating, and other options can be reviewed according to material and functional requirements.

Masking areas, cosmetic surfaces, and critical fits should be identified on the drawing whenever possible.

Quality Control for Aluminum Machined Parts

Drawing-Based Inspection

Critical dimensions, hole positions, threads, and mating features are checked against the agreed drawing requirements.

Flatness & Functional Surfaces

Mounting faces, thermal interfaces, sealing surfaces, and other functional features can be included in the inspection plan.

CMM Inspection

CMM reports are available for complex geometry and datum-related features when required.

Cosmetic Inspection

Visible surfaces, anodizing condition, scratches, edge damage, and other agreed appearance requirements can be checked before shipment.

From CAD File to Aluminum Parts

01. Send Your Files

Upload your 3D CAD model, 2D drawing, alloy, quantity, finish, and critical requirements.

Parts are machined using the agreed process, finished as specified, and inspected against the defined requirements.

04. Validate & Repeat

Approve the initial parts before carrying confirmed machining, finishing, and inspection requirements into repeat orders.

Your questions answered

Aluminum CNC Machining FAQ

Is 6061 or 7075 better for my CNC part?

6061 is a practical choice for many general-purpose parts because it balances machinability, strength, corrosion resistance, finishing flexibility, and cost. 7075 is often selected when higher strength-to-weight performance is required.

Can anodizing affect critical dimensions?

Yes. Anodizing can affect surfaces, threads, fits, and edges. Critical features and masking requirements should be identified before machining and finishing.

Can you machine thin-wall aluminum housings?

Yes, subject to geometry review. Wall thickness, depth-to-width ratio, clamping strategy, internal radii, tolerances, and finishing requirements all affect deformation risk and the machining approach.

What should I send for an aluminum CNC quote?

Send your 3D CAD file, 2D drawing if available, alloy and temper, quantity, surface finish, critical tolerances, thread requirements, cosmetic surfaces, and inspection requirements.

Have an Aluminum Part to Manufacture?

Send us your CAD files and drawings with the aluminum grade, quantity, finish, and critical requirements.

Our engineers will review alloy selection, manufacturability, machining strategy, tolerances, anodizing impact, and inspection requirements before providing a quotation.
