Machining
for Aerospace

Machining for aerospace demands a higher level of precision, consistency, and documentation than most industries. Twin City EDM & Manufacturing supports aerospace OEMs and Tier 1 suppliers with precision-machined components that meet critical specifications for flight, defense, and control systems.

We work with hardened alloys, tight tolerances, and complex geometries—and deliver parts that perform under pressure.

Precision Machining for Aerospace Components

Aerospace parts require precision at every level, from the first prototype to full production. Many of the components we produce have minimal features, strict tolerance stacks, or unusual materials that require a multi-process approach.

We support machining for:

Fuel system components
Sensor bodies and electrical connectors
Structural support parts and brackets
Landing gear interfaces
Custom fastening systems

Our multi-axis mills, Swiss machines, and EDM equipment enable us to deliver accurate, burr-free parts in a range of materials. Common metals include aluminum, titanium, high-strength steels, and Inconel.

Aerospace Manufacturing That Goes Beyond Machining

Many aerospace components require multiple machining processes, and we tailor our plan for each part based on its performance requirements and geometry.

We routinely combine:

Swiss turning for long, slender profiles
5-axis milling for complex curves and pockets
Sinker and wire EDM for features that must hold shape after heat treatment
Laser welding to join tight assemblies without distortion
Laser marking for traceability and compliance
Passivation, plating, and electropolishing as final finishing steps

By keeping these capabilities in-house, we help reduce total lead time and ensure that quality remains controlled from start to finish.

Built for Complexity and Collaboration

Twin City EDM is known for taking on jobs that other shops won’t touch. This includes thin-wall housings, blind internal cavities, tight-tolerance pin holes, and parts that require multiple complex features—especially after hardening or surface treatments.

We support:

Design for Manufacturability (DFM) input during early stages
Rapid prototyping for test builds and functional validation
Fixture design and process planning for complex geometries
Short runs and low-to-mid volume production for specialized platforms
