CNC Turned Aluminum 6061-T6 Camera Housing Tube 40mm OD IP66 Sealed Anodized Black

This camera housing tube is machined from Aluminum 6061-T6 (6061-T6) to ±0.02mm in the critical dimensions, then finished by Type II black anodized sealed grooves. It is produced on CNC turning centres that are dedicated to small and medium volume precision work, so every dimension on the drawing is generated by the machine rather than by hand fitting. Typical users are engineers who have already been let down by a supplier that quoted a tolerance it could not hold, and who need the part to fit the first time without sorting or rework on the assembly line.

• Sealed Groove Geometry: O-ring grooves are cut to 2.5 by 1.5mm with a controlled surface finish so the seal compresses evenly to reach IP66
• Bore Concentric To OD: 0.02mm concentricity keeps the lens axis aligned with the sensor mount inside the tube
• Anodized Inside And Out: Anodize inside the bore prevents galvanic corrosion where the lens mount seats
• Threaded End For Lens Mount: Internal thread is cut in the same setup as the bore, avoiding the tilt that comes from second operation threading
• Machined Vent Port: Optional M5 vent port is drilled and tapped for a breathable membrane gland

The process route is fixed before metal is cut. Bar stock is verified against the purchase specification and the heat number is logged, then a first article is turned and measured in full. Only after the first article is signed off does the lot run. Critical features on this camera housing tube are controlled to ±0.02mm with a process capability target of Cpk 1.33 or better, and the operator checks the feature at a defined frequency with the gauge stated on the control plan. Where the drawing calls for Type II black anodized sealed grooves, the finishing step is carried out in house and the result is measured, not assumed. Sample parts go to the CMM for full dimensional verification, and the recorded results ship with the lot as a first article inspection report in PPAP level 3 format when a customer program requires it.

Questions are handled by engineers rather than by sales staff. Our team reviews each drawing for manufacturability, flags features that would drive cost without adding function, and proposes the tolerance band that actually matters for the assembly. That review is free and is returned within 24 hours together with a quotation. When a part fails in the field, we ask for the sample back, section it if needed and report what the failure mechanism was, because a supplier that cannot explain a failure cannot prevent the next one.

Parts are degreased, dried and packed so that the surface finish specified above arrives intact. Standard packing is VCI paper or individual PE bag, a partitioned foam tray for form features, and an export grade corrugated carton on a pallet, with the lot number and heat number marked on the outside. Parts are warranted against material and workmanship defects for 12 months from delivery. If a part is found outside the drawing, we replace it at our cost and we pay the return freight for the defective lot. Third party inspection by SGS, BV or TUV can be arranged before shipment at your request, and we work under NDA where drawings are confidential.

Q: Can you confirm the housing will actually reach IP66? A: We machine the seal grooves and supply the O-rings as a kit. We test sample assemblies in a pressure and spray rig, and can run an immersion test on request.

Q: Is the anodize layer safe inside the bore for a lens mount? A: Yes, the anodize is thin and does not affect the bore tolerance because we cut with a pre-anodize allowance and re-check after coating.

Q: What wall thickness do you recommend for a deep water version? A: For more than 10m depth we step up to 4mm wall and specify 6061-T651 with a hydrostatic test. Send the depth target and we will advise.

Q: Do you supply the end caps and O-rings? A: We machine the tube, caps and retaining rings as a kit and can source standard O-rings in NBR or silicone.

Q: How do you confirm the Aluminum 6061-T6 material before it is machined? A: Every bar is checked against its mill certificate with an optical emission spectrometer before it goes to a machine. If the chemistry does not match the grade, the bar is rejected and returned. The certificate for your lot is filed under the heat number and can be sent with the shipment or on request.

Q: What happens if a delivered part measures outside the ±0.02mm tolerance? A: Send the measurement and the lot number. We check the recorded values for that lot, replace the parts at our cost and cover the return freight. Because each critical feature is recorded during production, we can trace the deviation to a tool wear step, a fixture shift or a gauge issue and correct the process before the next lot runs.

Send a 2D drawing, a STEP file or a sample and you will have a manufacturability review and a firm quotation within 24 hours. Trial orders from a single piece are accepted, so the tolerance claim can be checked on your own assembly before a production order is placed.
