Manufacturing and Quality System

A buyer-facing view of process capability: machine envelope, quality checkpoints, CMM control, and lot-level traceability.

This page is structured for sourcing and engineering reviews before PO release, with measurable control points rather than generic claims.

Equipment Capability Matrix

Cell TypeCore CapabilityOutput RoleBuyer Value
CNC turning/millingPrecision shaft, housing, flange, and interface machiningCritical geometry and interface consistencyReduces assembly mismatch and revision churn.
Reducer assembly cellControlled reducer assembly and preload consistencyBacklash and stiffness stabilityImproves repeatability between sample and MP lots.
Motor winding/testElectrical checks for winding and insulation integrityTorque constant and thermal baseline assuranceLowers early-life failure and rework exposure.
Final integrationFunctional, noise, and motion-profile verificationOutgoing lot acceptance readinessDelivers decision-ready inspection evidence.

Quality Process Flow

  1. Incoming validation: material cert review, dimensional sampling, supplier-lot identity capture.
  2. In-process checks: CTQ-based patrol inspections, assembly parameter records, abnormal escalation.
  3. Final inspection: functional checks, key metric logging, outgoing release gates by lot.
  4. Shipment release: packing checklist, label consistency, and document-package verification.

CMM and Tolerance Control

  • CTQ dimensions are measured with a defined sampling frequency and recorded by lot.
  • Interface geometry (shaft, flange, housing datum) uses pass/fail thresholds agreed during sample stage.
  • Trend checks are used to flag drift before mass-production impact.

Batch Consistency Narrative

  • Sample-to-MP transfer keeps the same revision baseline and CTQ acceptance criteria.
  • Outgoing records are indexed by lot for buyer-side audit and field issue triage.
  • Process changes follow revision notice and effective-lot governance.
