ISO 9001
Quality-system documentation for supplier review
Quality and Compliance
Gearbox Quality Controls Built for Supplier Qualification
Manufacturing, inspection, documentation, and export packing controls for robotized gearbox, RV reducer, harmonic reducer, and heavy industrial gearbox programs.
CE Support
Compliance file review when gearbox scope applies
7 Stages
Drawing, machining, inspection, run-in, and OQA
FOB / CIF / DAP
Transparent export terms and packing records
Process Control
7-Stage Gearbox Quality Workflow
The workflow is designed for procurement teams that need evidence before approving a replacement supplier, not only a catalog torque rating.
Requirement and Drawing Review
Nameplate, 2D/3D drawing, interface dimensions, service factor, and application assumptions are checked before quotation lock.
Material and Blank Verification
Steel grade, forged blank condition, incoming dimensions, and material certificate requirements are aligned with project scope.
CNC Machining Control
Gear profiles, shafts, bores, pilots, mounting faces, and housing datum features are controlled by drawing revision.
Heat Treatment and Hardness Check
Case depth, HRC target, distortion risk, and post-treatment dimensional stability are reviewed for critical gears and shafts.
Metrology and Interface Inspection
CMM, runout, concentricity, pitch, lead, backlash, and shaft/bore dimensions are inspected against agreed CTQ points.
Assembly, Run-In, and NVH Review
Bearing preload, lubrication, sealing, temperature rise, vibration, and noise are checked before outgoing release.
Outgoing Audit and Export Packing
Nameplate, paint, rust prevention, packing photos, shipping marks, commercial documents, and final inspection records are prepared.
Supplier Qualification
Certification and Inspection Document Matrix
| Document | When It Matters | Buyer Value |
|---|---|---|
| ISO 9001 quality system file | Supplier onboarding and annual vendor review | Shows the manufacturing process is managed through documented procedures and traceable records. |
| CE declaration or compliance file | EU machinery programs where gearbox scope requires CE support | Helps procurement and engineering align machine safety documentation before import or installation. |
| Material certificate | Critical gears, shafts, housings, and heat-treated components | Connects the finished gearbox to steel grade, heat number, and material specification controls. |
| Dimensional inspection report | Drop-in replacement, custom shaft, custom bore, or pilot fit | Reduces installation risk by proving controlled dimensions before shipment. |
| Run-in and performance record | High-duty automation, robot axes, heavy gear units, or sample approval | Documents temperature, noise, vibration, leakage, and assembly behavior before buyer validation. |
| Packing and shipping file | Export orders, heavy gear units, urgent MRO replacement, or DAP delivery | Makes receiving inspection easier and reduces freight damage disputes. |
Export Terms and Packing Controls
- FOB review for buyer-appointed forwarders and port loading.
- CIF review for ocean freight and marine insurance planning.
- DAP review for destination-side delivery coordination.
- Packing photos, shipping marks, rust prevention, and receiving notes can be prepared for heavy gear units.
RFQ Inputs for Quality Planning
- Target gearbox model, drawing, and existing nameplate photo.
- Critical dimensions, backlash target, duty cycle, and load case.
- Required inspection reports, certificates, and acceptance tests.
- Destination country, Incoterm preference, and packing constraints.

Quality FAQ
Can you provide certificates before we place an order?
We can share available quality and compliance files during supplier screening. Final project documentation depends on gearbox family, factory scope, destination market, and agreed inspection requirements.
Do all gearbox orders include CMM and run-in reports?
Not automatically. Standard outgoing checks are included, while detailed CMM, material, run-in, noise, or heat-rise reports should be specified in the RFQ so they can be priced and scheduled correctly.
How do you handle drop-in replacement quality risk?
We start with drawing and nameplate review, then freeze CTQ dimensions such as shaft height, pilot, bore, bolt circle, backlash, shaft direction, and mounting position before sample release.
Which Incoterms can you support?
Typical export projects can be reviewed under FOB, CIF, or DAP depending on buyer forwarder preference, destination, shipment size, and required insurance or door delivery support.
