Metrology & Process Precision
Precision Turned Parts Engineering Standards: Micron-Level Fidelity
Turned rotational components are defined by more than outer diameter dimensions; concentricity, roundness, runout, cylindricity, and surface topography determine operational life in demanding kinematic assemblies.
Multi-Spindle Swiss Turning (7-Axis / 9-Axis)
Our sliding-head Swiss machines utilize synchronous guide bushings to eliminate bar stock deflection, enabling length-to-diameter aspect ratios up to 25:1 without center distortion. Dual opposing spindles execute simultaneous back-machining, tapping, cross-drilling, and micro-broaching in a single cycle setup.
Exacting GD&T & CMM Coordinate Metrology
Every critical batch destined for San Francisco OEMs undergoes automated verification on Carl Zeiss 3D Coordinate Measuring Machines (CMM) and Mitutoyo roundness testers. Total Radial Runout (TRRO) is tracked at ±0.003 mm, and cylindrical thread geometry conforms with MIL-S-8879 and ANSI/ASME standards.
Advanced Metallurgical Spectrum
We process standard free-machining alloys as well as exotic materials: 17-4PH H900/H1150, Inconel 718/625, Hastelloy C-276, Titanium Grade 5 & Grade 23 (ELI), OFHC Copper (C10100), Beryllium Copper (C17200), and engineering plastics including PEEK, Torlon, Vespel, and Delrin.

Technical Sourcing Intelligence
Frequently Asked Questions by San Francisco Engineering & Sourcing Teams
Comprehensive engineering clarity regarding design guidelines, lead times, export protocols, and quality assurance standards.
What are your true dimensional tolerance limits on micro-turned components?
On high-precision Swiss-type turning centers (such as Citizen and Star lathes), critical diameters on materials like 303/304/316 stainless steel, brass, and aluminum can be maintained within ±0.005 mm (0.0002 inches) with CpK values ≥ 1.33. For turned micro-shafts and capillary components, runout and concentricity are held within 0.005 mm depending on the length-to-diameter ratio. During the preliminary DFM stage, our engineering group evaluates GD&T callouts to establish stable cutting parameters before tooling commitment.
How do you handle IP protection and NDA execution for early-stage Silicon Valley startups?
We sign bilateral Non-Disclosure Agreements governed under California or international commercial law prior to receiving 2D PDF drawings or 3D STEP/IGES models. Because Sunmy Hardware is an integrated owner-operated manufacturing facility—not a broker or trading house—your CAD data is stored on secure internal servers and accessed solely by assigned CAM programmers and metrologists. Your technical designs are never outsourced to third-party sub-contractors.
What is the standard turnaround time for rapid prototypes versus mass production runs into California?
For urgent DVT/EVT functional prototypes (10 to 500 units), standard production cycle time is 3 to 7 working days. Utilizing international priority air express direct to SFO or Oakland, parts arrive on your test bench in under 10 business days total. For scalable volume orders (10,000 to 500,000+ units), lead times run between 2 to 4 weeks depending on required surface post-treatments (electroless nickel, hard-coat anodizing, gold plating, passivating). Blanket order releases and localized inventory stocking programs are also supported.
What quality control paperwork and material traceability reports accompany shipments?
Every shipment arrives with full documentation: Certified Mill Test Reports (MTRs) validating chemical and mechanical properties of raw bar stock; First Article Inspection (FAI) reports conforming to AS9102 or ISO standards; Carl Zeiss CMM coordinate measurement data; surface roughness profilometer readouts; and Certificate of Conformance (CoC) verifying compliance with RoHS, REACH, and California Proposition 65 requirements.
How does your engineering team support Design for Manufacturability (DFM) to reduce unit costs?
Upon CAD submission, our manufacturing engineers perform an automated and manual DFM screening within 24 hours. We evaluate wall thicknesses, tool relief grooves, thread entry chamfers, undercut depths, and deburring challenges. By recommending standard tool radii, standard bar stock sizing, and eliminating secondary setups through live-tooling Swiss turn-mill operations, we regularly reduce per-unit machining cycle time by 20% to 35% without altering mating functional geometry.
Can you support surface treatments and cleanroom packaging for sensitive medical and optical hardware?
Yes. We manage a full suite of precision surface treatments: MIL-A-8625 Type II & Type III hard anodizing (with zero optical bounce black finishes), ASTM A967 citric and nitric acid passivation for medical stainless steels, ASTM B488 electrolytic gold plating, chemical electroless nickel (ENP), and electropolishing. Clean-sensitive parts undergo ultrasonic deionized aqueous degreasing and vacuum heat-sealed nitrogen-flushed poly packaging to prevent surface contamination during transpacific transit.
