Product Overview
This 5-axis CNC machined 6061 aluminum circular cavity device housing is a one-piece precision enclosure designed for optical modules, detection sensors, automation instruments and compact electronic assemblies. The hollow cylindrical cavity carries internal threaded mounting posts and locating holes, while the outer wall is stepped with multi-stage sealing grooves so the unit seals reliably against end caps, covers or mating flanges.
Every housing is milled from a solid 6061 aluminum billet on 5-axis simultaneous CNC machining centers in a single clamping, keeping the cavity, thread posts, locating holes and sealing steps concentric and square to each other. Critical features are held to ±0.01mm and verified on a CMM before anodizing.
Manufacturing Process
- Certified 6061 aluminum billet selection with material certificate and traceability.
- 3-axis roughing of the outer profile and cavity to hold uniform finishing allowance.
- 5-axis simultaneous finishing of the cavity wall, sealing steps and peripheral mounting ears in a single clamping.
- Drilling and tapping of internal threaded posts and locating holes with thread-gauge and position checks.
- Deburr, ultrasonic clean, then anodizing (clear, black or hard) for protection.
- CMM (Zeiss) full-dimension check, protective packing and photo confirmation before shipment.
Precision & Sealing Control
Dimensional Tolerance
±0.01mm
Cavity Concentricity
≤0.02mm
Sealing Surface
Ra 0.4–0.8μm
Wall Thickness Control
±0.05mm
The circular cavity is bored and finished concentric with the outer sealing steps so that end caps and O-rings seat evenly all round, avoiding the leak paths that come from mismatched machining. Internal threads are verified with thread gauges for proper component engagement, and the sealing groove profile is controlled for consistent O-ring compression. Air-leak testing can be added on request for IP-rated assemblies.
Material & Finish
6061-T6 aluminum gives the housing a high strength-to-weight ratio, stable machining and good thermal conductivity, keeping optical and electronic modules cool and light. 6063, 7075 and 2A12 aviation aluminum are available for specific needs. Clear, black and hard anodizing protect the surface against corrosion and handling wear while keeping the finish clean and professional.

Frequently Asked Questions
Q: Can you machine a housing to my cavity and thread layout?
A: Yes. Send your STEP, IGES, STP or DWG drawing; we machine the exact cavity, thread-post and sealing-groove layout and return a DFM review within 24–48 hours.
Q: What tolerance can you hold on the cavity and sealing steps?
A: ±0.01mm on critical dimensions with cavity concentricity within ≤0.02mm, checked on a CMM before anodizing.
Q: Can you add a leak/IP test?
A: Yes. Air-leak testing can be added on request for IP-rated sealed assemblies, with results documented in the inspection report.
Q: What is the minimum order quantity?
A: We accept orders from 1 piece for prototypes and scale to thousands per month for series production.
Q: How do you ensure stable delivery?
A: Multi-machine capacity of 20,000 pcs per month, reserved production slots and in-process CMM checks keep lead times predictable: samples 7–12 days, small batch 12–18 days, mass production 15–25 days.
Q: What surface finishes are available?
A: Clear, black and hard anodize, plus bead blast and laser marking, chosen to match your application and appearance requirements.
