CNC Turning
Stable turning for sleeves, shafts, fittings, threads, and concentric features.
Finishing Services
Anodizing, conversion coating, blasting, polishing, and coating planned around final dimensions.
Aluminum Machining Tolerance Standards
Tolerance capability depends on alloy, feature size, wall thickness, setup access, finish, and inspection method.
Drawing Defined
Critical fits and datums are reviewed from the drawing.
Feature Specific
Capability changes with size, depth, wall, and tool access.
Finish Aware
Coating build and masking are included in final dimensions.
Inspection Matched
Measurement method is selected around the requirement.
Comparison of Common Aluminum Alloys
Compare strength, machinability, finishing response, and application fit before selecting stock.
Final selection should be confirmed against the drawing, service environment, stock condition, finish, and documentation requirements.

Best Practices for Aluminum CNC Machining
Geometry, stress, fixturing, and tool access have a direct effect on stability and finish.
Geometry Fundamentals
Use practical internal radii, reachable pockets, and consistent wall sections.
Stress Management
Plan stock removal and datum strategy to limit movement in plates and thin walls.
Fixturing Strategy
Support cosmetic and flexible features without marking or over-constraining the part.
Tooling Selection
Match cutter geometry, reach, coolant, and engagement to the alloy and feature.
CNC Machined Aluminum Applications
Lightweight, corrosion-resistant parts for performance-focused products.
Aerospace structures
Lightweight brackets, housings, and structural components.
Robotics
Frames, end-effectors, covers, and motion-system parts.
Electronics
Heat sinks, enclosures, and precision mounting plates.
Electronics and Thermal
Precision components planned around the actual load, environment, assembly, and documentation needs.
DFM for Aluminum CNC Machining
Small design decisions can reduce setup count, tool reach, distortion, and total machining time.
Optimize Internal Radii
Use radii compatible with standard cutters and avoid sharp internal corners.
Maintain Rigid Wall Thickness
Keep walls consistent and support tall or thin features where possible.
Limit Cavity Depth
Reduce deep narrow pockets that require long, flexible tools.
Smart Tolerancing
Reserve tight tolerances for functional datums, fits, and interfaces.
Thread Depth Control
Specify useful engagement without unnecessary full-depth threading.
Surface Finishes for CNC Machined Aluminum Parts
Finish selection should include coating build, masking, color range, cosmetic class, and protected features.

Got Questions about Aluminum Machining?
Useful points to resolve before requesting production.
Which aluminum alloy is easiest to machine?
6061-T6 is a common starting point because it machines consistently, is widely available, and accepts several finishes.
When should I choose 7075?
Choose 7075 when higher strength and stiffness are more important than weldability or cost.
Can tight fits be anodized?
Yes, but the expected coating thickness should be included in the tolerance and masking plan.
What information should I send for a quote?
Send a 3D CAD file, dimensioned drawing, material or grade, quantity, finish, critical features, and target schedule.
