According to our CNC machining knowledge base, CNC machining is a computer-controlled subtractive manufacturing process that uses milling, turning, or drilling to shape materials with high precision. A sensor housing is more than a protective shell: it defines EMI shielding effectiveness, thermal dissipation, sealing integrity, and connector alignment. A mating face that is out of flatness by 0.02mm can break an IP67 seal; a connector bore off by 0.1mm can misalign a cable harness during assembly.
At CNC Works AI, we mill housings directly from solid billet, giving you complete design freedom for mounting bosses, internal standoffs, connector cutouts, and thermal features. Machining from solid aluminum also creates a natural Faraday cage for EMI/RFI shielding, protecting sensitive PCBs from electromagnetic interference.
Each enclosure is engineered for protection, signal integrity, and easy assembly.
Rugged aluminum enclosures for proximity, pressure, and temperature sensors in factory automation. Designed for DIN rail, bracket, or flush mounting.
Compact housings with integrated antenna windows, cable glands, and PCB standoffs machined directly into the floor for vibration-proof assembly.
Precision ports and diaphragm sealing surfaces machined to ±0.005mm. Compatible with NPT, BSPP, and metric process connections.
ADAS enclosures with precise lens bores, sealing grooves, and thermal interfaces. Machined to keep optics aligned under vibration and thermal cycling.
Prep for glass-to-metal or ceramic-to-metal seals. Tight dimensional control ensures reliable feedthrough installation and leak-free performance.
Biocompatible PEEK and 316L stainless housings with smooth finishes and minimal crevices for cleaning and sterilization compatibility.
Real-world sensor housings machined for OEMs and integrators.
Milled from solid 6061-T6 with EMI shielding walls.
316 SS with NPT ports and diaphragm seat.
Lid with M12 and cable gland cutouts.
High-temp insulating sensor sleeve.
7075-T6 housing with thermal pad pocket.
Stainless base prepared for glass feedthrough.
Every material balances shielding, weight, corrosion resistance, and insulation.
Lightweight, excellent machinability, natural EMI shielding, and good thermal conductivity for most industrial enclosures.
Higher strength for rugged field sensors and ADAS housings where impact resistance matters.
Superior corrosion resistance for pressure, chemical, and marine sensor applications.
High-temperature, chemically resistant polymer for insulating and medical sensor components.
A sensor-specific workflow from billet to sealed, shielded enclosure.
We review connector positions, wall thickness, sealing grooves, and thermal paths to prevent warping and tolerance stack-up.
High-speed dynamic milling removes material gently, minimizing chatter and distortion on delicate enclosure walls.
Connector cutouts, cable gland holes, and process threads are machined to exact position and thread class.
Anodize, passivate, or electropolish is applied, followed by CMM verification and seal-fit testing.

Verifications that protect signal integrity and sealing performance.
All sealing faces, bores, and connector positions verified to drawing with NIST-traceable CMM.
Sealing surfaces checked to Ra 0.4μm or finer to ensure gasket and O-ring compression.
IP67-rated housings are pressure-tested to verify seal integrity before shipment.
Every process thread and connector interface checked with go/no-go gauges.
We also machine sensor mounts, connector interfaces, hermetic lids, and cable gland adapters. Upload your drawing and our engineers will respond within 4 hours.
Submit Your DrawingFor most industrial and IoT sensor housings, we recommend 6061-T6 aluminum because it is lightweight, machines cleanly, and provides natural EMI/RFI shielding. For pressure, chemical, or marine sensors, 316 stainless steel offers superior corrosion resistance. PEEK is ideal for high-temperature or insulating medical sensor applications.
Yes. IP67 sealing depends on flat sealing faces, correctly sized O-ring grooves, and proper surface finish. We machine sealing faces to flatness within ±0.01mm and surface finish of Ra 0.4μm or better, then verify seal integrity with pressure testing. Every cutout must be sealed with matching cable glands or connectors to maintain the rating in the final assembly.
According to our research, machining a housing from a solid billet of aluminum creates a natural Faraday cage that shields internal PCBs from electromagnetic interference. We can also design shielding walls, grooves for conductive gaskets, and precise mating seams to maximize shielding effectiveness.
Our standard CNC machining tolerance is ±0.005mm. For critical features such as lens bores, sealing faces, and feedthrough holes, we hold ±0.005mm to ±0.002mm with surface finishes down to Ra 0.2μm. Every part is inspected on CMM before shipment.
Yes. We use high-speed dynamic milling strategies and sharp carbide tooling to remove material gently without warping thin walls. This approach is common for compact IoT and RF sensor enclosures where internal volume must be maximized while keeping exterior walls thin and light.
Yes. Milling standoffs directly into the housing floor guarantees perfect PCB alignment and a secure, vibration-proof mount. We also machine precise rectangular and circular connector cutouts for USB, M12, power jacks, cable glands, and custom I/O.
We offer Type II anodizing for aluminum enclosures, Type III hard coat for wear resistance, passivation and electropolishing for stainless steel, and laser marking for labeling. Finishes are selected based on environmental exposure, cosmetic, and functional requirements.
