Aerospace Jigs & Fixtures

Engineering Aerospace Assembly Jigs for Zero-Compromise Alignment

Aerospace assembly jigs and fixtures represent the structural backbone of airframe manufacturing. At Metro Precision Engineering Works, we design and fabricate high-stability holding and alignment tools that maintain absolute dimensional integrity across drilling, riveting, bonding, and sub-assembly operations. Every jig we deliver is engineered to resist deflection under load, accommodate thermal expansion differentials, and provide repeatable datum references that satisfy tier-1 audit protocols for Boeing, Airbus, and defense OEM supply chains.

Our jigs span monolithic frame structures for fuselage sections, wing box alignment tools, engine pylon holding fixtures, and modular drill jigs for sheet metal sub-assemblies. We work from client-supplied CATIA, NX, or SolidWorks datasets, or develop tooling layouts collaboratively through our in-house design consultancy. Material selection prioritizes aerospace-grade aluminium alloys, precision-ground steel components, and hardened locators where wear resistance is critical.

Design Methodology

Each project begins with a tolerance stack analysis that maps critical features to manufacturing sequence constraints. We evaluate clamping forces, accessibility for operators and automated drilling systems, and interchangeability for multi-variant aircraft programs. Finite attention is paid to datum scheme definition — primary, secondary, and tertiary references are physically embodied in hardened bushings, precision pins, and CNC-machined locating surfaces that are inspected against calibrated metrology equipment before release.

For developmental programs with evolving geometry, we incorporate adjustable shims, replaceable wear plates, and modular sub-fixture interfaces that reduce re-tooling cost when engineering changes arrive late in the design cycle. This agility has proven essential for space launch vehicle integrators and defense platforms where design maturity trails production demand.

Manufacturing & Validation

Fabrication occurs within our ISO 9001:2015 certified 140 sq.m production cell using 3-axis CNC machining (bed capacity 1000×500×500mm), conventional milling with digital readout, turning, surface grinding, and certified structural welding. Large sub-assemblies are stress-relieved when weld distortion risk is identified. We maintain full material traceability from mill certificates through final inspection reports.

Validation includes in-house dimensional layout against CAD nominal, with outsourced CMM inspection available for first-article and periodic re-certification requirements. Every jig ships with an identification plate, datum map documentation, and maintenance guidance for bushings and wear components. Our quality team coordinates directly with client QA representatives to close non-conformance reports within aerospace-standard timelines.

Applications & Industries

• Commercial aviation airframe and engine program tooling
• Defense aircraft structural assembly and MRO support fixtures
• Space launch vehicle stage integration and payload adapter jigs
• Sheet metal drill and route template integration into master jigs

Whether you require a single prototype jig for design validation or a family of serial-production fixtures for high-volume lines, Metro Precision Engineering Works delivers tooling that integrates seamlessly into your production cell — with the engineering responsiveness and ISO discipline that tier-1 procurement teams demand.

Engagement Model

Programs typically progress through technical feasibility review, formal quotation against released drawings, first-article manufacture with joint inspection, and serial release with agreed delivery schedules. Metro Precision assigns a single engineering point of contact for each program to streamline communication through design changes, expedite requests, and quality closures — a model proven across Safran, Honeywell, Tata, and space launch supply chains operating from Hyderabad.
