Aluminum CNC Machining

Aluminum is the default choice for robotics, automation, and portable equipment because it combines a high strength-to-weight ratio, good corrosion resistance, and excellent machinability. Bedelo supplies custom aluminum components machined from bar stock, plate, and near-net forgings, covering single prototypes through repeat production. We confirm material grade, temper, and surface finish before cutting metal, so the part you receive matches the functional requirement — not just the nominal dimensions on the drawing.

Grades We Machine

Common grades include 6061-T6 for general structural parts and fixtures, 7075-T6 for high-strength applications such as robot links and loaded brackets, 5083 for welded frames and marine environments, 2024 for fatigue-critical components, and 6082 where European drawing standards apply. Grade and temper affect machinability, distortion, and anodizing response, so we review them together with your tolerances rather than substituting whatever stock is on the shelf.

Milling, Turning, and Multi-Axis Work

Aluminum parts are machined on three-axis and multi-axis milling centers, CNC lathes, and mill-turn equipment depending on geometry. Thin walls, deep pockets, and large plate work require light-pass strategies and stable fixturing to control deflection. Where a part carries features on several faces, multi-axis machining reduces setups and keeps datums consistent — which matters for assemblies that have to fit on the first try.

Surface Finishes

We coordinate anodizing (Type II and hard Type III), bead blasting, chromate conversion coating, and powder coating through qualified finishing partners. Finish choice affects dimensional allowance, thread fit, and masking requirements, so it should be specified on the drawing or agreed during review rather than decided after machining.

Where Aluminum Parts Are Used

Typical applications include robot arm segments, end effectors, joint housings, automation fixtures, heat sinks, optical instrument bodies, and equipment enclosures. If your part is weight-sensitive or has thin features, send the drawing and we will flag the areas most likely to distort during machining. Where a design calls for hard anodizing on thin walls, we discuss allowance and masking before cutting, so the finished part still meets the drawing after coating.
