This precision engineering CNC turning part is purpose-built as a dimensional-critical housing for modern automotive sensing systems. Produced on multi-axis Swiss-type turning centers, each unit holds tolerances down to ±0.01mm, guaranteeing that every sensor seats perfectly inside its mounting bore without shimming, reaming or rework. The housing geometry is generated directly from your CAD model, so wall thickness, thread depth and sealing grooves match the drawing the first time and every time after that.

Because automotive electronics demand interference-free fits, we machine the internal bores and the outer locating diameters in a single setup, which eliminates repositioning error between operations. Controlled cutting parameters keep the material cool, preventing thermal growth that could otherwise distort a finished bore. The result is a repeatable, fully interchangeable component that drops straight into your assembly line and performs exactly as specified, batch after batch, year after year.

• Sub-Micron Repeatability: Machines fitted with thermal compensation hold dimensional drift below 0.005mm across an entire production run.
• Single-Setup Swiss Machining: Turning, drilling, threading and slotting complete in one operation, removing stacked tolerance errors.
• 100% CMM Inspection: A coordinate measuring machine report accompanies each shipment for complete dimensional traceability of every bore.
• Fine Surface Finish: Controlled feeds and sharp tooling deliver Ra0.4-Ra1.6 finishes that seal reliably against O-rings and gaskets.
• Material Versatility: Available in 303 and 304 stainless steel, 6061 aluminium and brass to match weight and corrosion targets.
• Rapid Tooling Changeover: Standard quick-change collets shorten lead time for a new part number to as little as seven working days.

These turned housings are widely used in crankshaft position sensors, ABS wheel-speed sensors, throttle position sensors and pressure transducers, where a stable air gap and a consistent fit directly affect measurement accuracy and service life.

Beyond automotive, the same precision approach suits flow meters, proximity switches and industrial temperature probes that require a sealed, dimensionally stable enclosure to protect delicate internal electronics from dust and moisture.

Parts are individually wrapped in anti-static foam, layered inside moisture-barrier bags and packed into export-grade corrugated cartons. Custom labelling, barcoding and kitting are available for automated pick-to-light assembly lines.

Every order ships with an ISO 9001:2015 certificate of conformance and a first-article inspection report. We stand behind each batch with a twelve-month quality guarantee against manufacturing defects and material non-conformance.
