Approved suppliers.
Verified on the factory floor before you procure.
The purpose of PROQRA is straightforward: we audit Indian precision engineering facilities in person, verify CapEx, machine condition, lead times, and materials, and oversee initial production so UK manufacturers can approve and procure from them with complete confidence.
Our 4-pillar on-site audit framework.
Certificates on a wall do not guarantee precision. We audit what is happening at the spindle, on the surface table, and on the shop floor.
CapEx & Machine Infrastructure
We inspect capital equipment investment, machine age, spindle runout, and true repeatable tolerances.
On-Site Inspection Checks:
- CNC axis condition, backlash, and controller capabilities
- Spindle runout, toolholder condition, and machine age verification
- Preventative maintenance schedules and OEM service records
- Tool wear management and insert replacement protocols
Supplier Production Lead Time & Capacity
We audit active machine loading, shift capacity, and material lead times to ensure dependable delivery.
On-Site Inspection Checks:
- Active machine shop loading schedules and available spindle hours
- Raw material procurement cycles and certified mill lead times
- Cycle time validation against UK batch volume requirements
- Buffer planning and committed dispatch milestone tracking
Quality Systems & Traceability
Ensuring shop-floor operating discipline matches UK drawing requirements.
On-Site Inspection Checks:
- ISO 9001 systems actively practiced on the machine floor
- Digital metrology, CMM, and gauge calibration records
- Raw material test certificates (MTC 3.1) tied to heat numbers
- Strict quarantine segregation of non-conforming parts
Workplace Safety & Discipline
A factory with poor safety culture cannot consistently deliver precision quality.
On-Site Inspection Checks:
- Machine interlocking, emergency stops, and electrical safety
- Mandatory PPE compliance across all operational bays
- Clear gangways, 5S floor discipline, and safe handling of workpieces
- Fair, compliant, and dignified working conditions
Processes & capabilities we qualify.
We focus our supplier approvals on precision mid-volume manufacturing where capital investment, machine tool stability, and raw material certification matter most.
Precision CNC Machining

Supplier Relationship
Direct Procurement
No ongoing broker margin
The approval dossier handed to your team.
When a supplier is approved, you receive the full technical proof before approving commercial production.
On-Site Factory Audit Scorecard
Machine registry, physical condition scores, operator skill evaluation, and verified capability limits.
First Article Inspection Report (FAIR)
100% measured values of all critical and nominal dimensions against your approved engineering drawings.
Material Mill Test Certificates (MTC 3.1)
EN 10204 3.1 certificates directly matched to the batch heat numbers of the raw metal.
Initial Production Setup Log
Recorded feeds, speeds, tool paths, cycle times, and dimensional stability across the first batch.
Direct Supplier Handover Pack
Direct factory leadership contacts, escalation hierarchy, and agreed production protocols for ongoing supply.
Zero blind procurement. You approve the supplier based on physical data.
Every measurement in the dossier is collected directly from the machine shop floor. We ensure spindle runout, material heat numbers, production lead times, and dimensional tolerances are verified in person before you authorize volume production.
