±5 μm drive shafts, CV joints, and gear hubs — IATF 16949 certified, shipped to 18 markets.
You eliminate downstream balancing rework because PrecisionAxis grinds drive-shaft journals to ±5 μm true position with 0.4 Ra surface finish — verified at 100% inspection on Zeiss CONTURA G2 CMM, traceable to ISO 17025 calibration.
You compress new-part qualification because every PA-series component ships with full PPAP Level 3 — control plan, FMEA, MSA, dimensional layout, and capability study Cpk ≥ 1.67 — aligned to AIAG and IATF 16949 protocol.
You deliver fatigue life beyond OEM warranty thresholds because journal surfaces are induction hardened to 58–62 HRC at controlled case depth, then stress-relieved — eliminating the spalling failure modes seen in flame-hardened competition.
You shorten lead time by integrating turning, milling, drilling, and cylindrical grinding within a single closed-loop cell — reducing setup variability and eliminating the inter-process logistics that fragment most Korean parts shops.
You meet IATF 16949 traceability without proprietary ERP dependence because every billet carries a 2D matrix code linked to heat lot, machining log, hardness data, and CMM dimensional report — exportable in AIAG-compatible format.
You receive DFMA review from in-house engineers within 5 business days of drawing submission — including tolerance optimization, hardening profile recommendation, and material substitution analysis — before quotation.
PrecisionAxis Korea manufactures three driveline component families covering passenger, commercial, and electrified powertrains — drive shafts, constant-velocity (CV) joints, and integrated gear hubs. All families share a single IATF 16949-certified production stream, PPAP Level 3 documentation, and the same Zeiss-verified ±5 μm geometric tolerance baseline.
Every PA-series part is measured on a Zeiss CONTURA G2 coordinate measuring machine before packaging, with calibration traceable to ISO 17025. Inspection reports export in AIAG-compatible format for direct import into customer SPC systems.
New-part introduction follows the full APQP roadmap with PPAP Level 3 deliverables: control plan, dimensional results, MSA, capability studies, FMEA, and qualified tooling records — submitted within 6 weeks of drawing release.
In-line induction hardening with closed-loop temperature feedback maintains 58–62 HRC at the journal with case depth 1.5–2.5 mm, eliminating the case-soft and surface-burn failure modes typical of open-loop flame hardening.
Each billet receives a 2D Data Matrix at incoming inspection, linked to heat lot, machining program, hardening log, CMM report, and balance data. Customers retrieve full part history through standard AIAG XML export — no proprietary dashboard required.
Submit a 3D drawing and PrecisionAxis engineering returns a DFMA review within 5 business days: tolerance stack-up assessment, hardening profile recommendation, alternate material analysis, and machining cost driver breakdown — before quotation.
Most parts pass dimensional inspection on the supplier floor and fail at the assembly line. PrecisionAxis was built to close that gap — verifying ±5 μm geometric tolerance at 100% inspection so customer goods-receiving never doubles the work.
Founded in 2009 by a senior driveline engineering team from a Hyundai-Mobis Tier-1 supplier, PrecisionAxis inherited the discipline of IATF 16949, AIAG, and APQP from day one — without inheriting the legacy ERP and proprietary documentation that slows new-part introduction.
Every PA-series part ships under standard PPAP Level 3 documentation at no additional engineering charge. Capability study results are reported with raw data attached. AIAG XML export is included by default — no proprietary dashboard subscription, no per-API call fee.
By 2030, EV drive units will operate at twice the rotational speed of legacy ICE shafts. PrecisionAxis is investing in 5-axis grinding, MQL coolant, and digital twin process control — to remain the verified-quality backbone of the next-generation driveline supply chain.
Korean precision parts manufacturers hold 11% of the global automotive driveline component supply.
Global driveline component supply is restructuring along two converging axes: powertrain electrification and accelerated supplier qualification timelines. EV drive units operate at higher rotational speeds (15,000–20,000 rpm continuous) and demand tighter geometric tolerance, tighter balance grade (G2.5 or better), and revised material selection — phasing out the slack-tolerance practices that legacy ICE shafts could absorb. Simultaneously, OEM and Tier-1 buyers are compressing new-part qualification cycles from 26 weeks toward 12 weeks, raising the bar for PPAP Level 3 readiness, APQP discipline, and AIAG-format traceability. Korean precision parts manufacturers operating IATF 16949-certified streams with Zeiss-verified dimensional inspection are positioned to absorb the volume migrating from cost-only Tier-3 sources — particularly for the German, US, and Mexican plants serving the EU and North American EV programs.
PA-DS shafts qualified to ±5 μm true position and G2.5 balance feed direct line-side, eliminating the inspection rework that previous Tier-3 sources required at goods-receiving.
PA-CV joints ship under PPAP Level 3 with closed-loop traceability and AIAG XML export, supporting Hyundai-Mobis's 8-week new-part qualification target across Korean, US, and Czech assembly plants.
PA-GH gear hubs through-hardened to HRC 28–32 and dimensionally inspected at 100% deliver the warranty fatigue life that commercial driveline programs require, validated under SAE J2452 fatigue protocol.
PA-DS Series shafts rated for 18,000 rpm continuous with G2.0 dynamic balance and 0.4 Ra journal finish meet the noise-vibration-harshness (NVH) targets of premium EV drive units without secondary balance correction.
PA-CV joints ship under distributor private label with EU-regional consolidation through the Antwerp logistics partner, holding 12-week safety stock for top-50 SKU coverage.

On purchase order, PrecisionAxis tools the part, machines a first-article batch of 500 pieces, and submits a PPAP Level 3 package — including control plan, capability study, MSA, and dimensional report — within 6 weeks.
Customer reviews the PPAP submission and issues a Part Submission Warrant (PSW). PrecisionAxis incorporates any required corrective actions and reissues PPAP within 2 weeks of customer feedback.
Serial production begins on PSW approval. Each shipment includes a certificate of conformity, full dimensional report sample (1 in 50 pieces), heat-lot traceability log, and AIAG-compliant labels — ready for direct line-side feed.
Yes. PrecisionAxis Korea is certified under IATF 16949:2016 by DEKRA Certification (audit cycle current through 2026), with ISO 9001:2015 and ISO 14001:2015 integrated. The certification covers all driveline product families and all production cells at the Hwaseong facility.
PrecisionAxis ships PPAP Level 3 by default — including control plan, FMEA, MSA, dimensional results, capability study (Cpk ≥ 1.67 on critical characteristics), qualified tooling records, and material certifications. Levels 4 and 5 are available on customer request without additional engineering fee.
PrecisionAxis Korea exports to 18 countries. Primary markets are Germany, the United States, Mexico, Japan, India, and the Czech Republic (VW Mladá Boleslav and Stellantis Trnava plants). Additional markets include Slovakia, Hungary, Thailand, Vietnam, Brazil, and Turkey.
Sample runs start at 500 pieces, intended for first-article qualification and customer PPAP review. Production MOQ is 5,000 pieces per part number per release; OEM and Tier-1 supply contracts negotiate dedicated tooling and lower per-release minimums based on annual volume.
From drawing release: tooling and first-article qualification within 8 weeks, PPAP Level 3 submission within 6 weeks, serial production within 10–12 weeks of PSW approval. Expedited PPAP timelines are available for design-frozen programs without geometry change.
