ISO 9001:2015 Certified Precision CNC Machining for Aerospace Components in India
Multi-axis CNC capability, GD&T-controlled tolerances, and documented traceability for flight-critical parts—built for program managers who need zero surprises at qualification.
Why ISO 9001:2015 Certification Matters for Aerospace Machining
ISO 9001:2015 is the baseline requirement for any aerospace machining source—not a point of differentiation. What matters is what the certification actually controls in a CNC environment.
The standard mandates documented process control, material traceability, and corrective action discipline. For flight-critical components, this is non-negotiable: a supplier without these systems cannot demonstrate repeatability, and repeatability is what an aerospace buyer is qualifying for.
Certification proves a third-party auditor has reviewed your inspection systems, tooling maintenance schedules, and first-article acceptance procedures—and found them compliant, not just claimed.
Soleil Technological Solutions is ISO 9001:2015 certified, with documented procedures covering CNC setup verification, tool offset validation, and in-process dimensional inspection. These procedures are auditable on request, not internal claims.
Multi-Axis CNC Capability for Aerospace Tolerances
Multi-axis CNC machining—3-axis through 5-axis—covers the aerospace part classes that carry the most qualification risk: structural brackets, engine mounts, and hydraulic valve bodies, typically held to positional tolerances of ±0.05 mm.
Soleil executes GD&T-controlled geometry, including perpendicularity, runout, and concentricity on critical datums, verified by CMM inspection rather than manual gauging alone.
Aerospace parts frequently carry material certification requirements—heat lot traceability and hardness verification among them. These are integrated directly into job travellers and final inspection records, so the paperwork ships with the part, not as an afterthought.
From CAD to Flight-Ready: Process Control Checkpoints
Intake: Drawing Review
Technical drawing review—GD&T validation, material spec, heat treat requirements—happens before quoting or scheduling. This catches design ambiguities before machining starts, not after scrap is generated.
Tooling & Setup Verification
CNC program verification runs on witness parts, with documented tool offsets. A capability study (Cpk ≥1.33 minimum) is required on critical dimensions before the full production run is released.
First-Article & In-Process Inspection
First-article inspection (FAI) is performed to the aerospace buyer's specification, followed by in-process sampling and 100% dimensional and visual verification on critical features at final inspection.
Documentation & Traceability
Inspection records, CMM reports, and material certificates ship with every delivery, giving your program the audit trail required for flight-critical acceptance.
Materials and Special Requirements
Aerospace-grade alloys—titanium, stainless steel, and aluminium alloys machined to AS9102 or equivalent specification—require certified material certs, hardness testing, and coordinated heat treat cycles. This burden does not sit with the buyer; it sits with the supplier.
Soleil sources certified material and manages certs as part of the job, integrating third-party testing—hardness, ultrasonic, radiography—as the drawing calls for it.
Non-metallic components, including machinable plastics for avionics enclosures, are supported with the same dimensional and material compliance documentation as metallic parts.
Quality Metrics and Accountability
Aerospace programs do not tolerate handoff risk. Here is how the accountability model is structured.
Single-Point Accountability
Soleil holds accountability for design review, tooling, inspection, and delivery within the machining scope—no sub-tier handoffs that dilute responsibility when something goes wrong.
Zero-Surprise Delivery
Schedule adherence, defect-free delivery, and documented traceability are treated as non-negotiable, not aspirational targets, on every flight-critical order.
Built-In Audit Access
First-Article Inspection (FAI) and ongoing supplier-customer audits are part of the engagement model from the first order, not something negotiated later.

How to Qualify Soleil as Your Aerospace CNC Supplier
A supplier qualification file should not require multiple rounds of follow-up. Here is what is available on request:
If your qualification checklist matches this list, the evaluation can move directly to FAI on a pilot order.
