Step 1
Machine the functional geometry
The part combines a cylindrical exterior with internal pockets, mounting features, and machined openings. The functional geometry needs to be established before cosmetic finishing begins.

The Project
A Decorative 6061 Aluminum Part That Still Has To Assemble Correctly
This real component set was made for a premium coffee machine application. The customer information, dimensions, quantity, and performance requirements remain confidential; the photographs document the actual 6061 aluminum parts and their mirror chrome appearance.
Unlike a hidden structural part, this component is seen up close. Its reflective exterior amplifies small scratches, polishing variation, burrs, and edge defects. At the same time, the internal pockets and holes must remain practical for downstream mounting and assembly.
The project demonstrates why aluminum CNC machining for consumer equipment should be planned as one route: CNC geometry, cosmetic edge control, polishing, chrome finishing, inspection, and packing all influence the delivered result.
Manufacturing Route
Machining And Chrome Finishing Need One Shared Plan
For visible aluminum components, a dimensionally correct part is only the starting point. The production route must protect the finished appearance without losing control of functional interfaces.
Step 2
Control visible edges and transitions
Rounded rims, opening edges, and the transition from the top face to the outer wall remain highly visible after a reflective finish. Tool marks, burrs, and edge inconsistency must be addressed before polishing.
Step 3
Prepare the surface for reflectivity
Mirror chrome does not conceal base-surface defects. Surface preparation and polishing are therefore part of the manufacturing route, rather than a final visual touch.
Step 4
Plan finishing around assembly interfaces
Threads, close fits, contact locations, and protected functional surfaces must be identified on the drawing so the finish plan supports the final coffee-machine assembly.
Design Review Focus
What We Would Review Before Production
- Which surfaces are cosmetic A-surfaces and which are functional or hidden.
- Where a finishing contact point or masked area can be placed without affecting the product appearance.
- Whether close bores, threads, or mating faces need a pre-finish dimensional allowance.
- How polishing and final packing can protect the surface through assembly and shipment.
RFQ Checklist
What To Send For A Similar Part
- A STEP, X_T, or IGES model plus a drawing for critical dimensions and datums.
- The specified 6061 grade or required aluminum equivalent, along with order quantity.
- A cosmetic standard: reference sample, accepted surface zone, and allowable rack or masking locations.
- Any thread, bore, grounding, or mating surface that needs dimensional review before finishing.
