Precision manufacturing for critical part production

Highly skilled in machining and manufacturing of fracture-critical components, ARCH provides aerospace and defense, space, and commercial aerospace OEMs a unique breadth and depth of precision-machining capabilities. We are a proven supplier of complex, precision-machined components in aluminum, plus hard metals ranging from high-nickel-based alloys to titanium. Our advanced multi-axis CNC machining, CNC tube bending, and comprehensive secondary and finishing operations produce intricate, difficult-to-manufacture, and tight-tolerance critical parts for customers who require capabilities that support the next-generation needs and demands for future design. Multi-axis, multi-spindle, long-bed machines allow us to efficiently produce parts from micro to massive.

Experienced in critical part applications

Our teams possess the knowledge and skills to provide high-quality precision-machined solutions—from micro to large envelope—for aerospace and defense manufacturers. Our expertise encompasses a wide range of demanding applications. ARCH has produced fracture-critical components and complex subassemblies for rockets, missile systems, satellites, Navy fleet, and state-of-the-art fighter jets. We are capable of machining tight-tolerance components in titanium, steel, or stainless steel in a heat-treated condition or high-nickel alloy.

One of our core competencies is the machining of very large, complex hard-metal structural components. High-torque, high-power, and multi-spindle machines are the winning combination for removing hard metal efficiently and quickly. We offer extensive capacity and multi-axis capability to produce very tight-tolerance shapes in hard metals as well as aluminum. With long-bed capabilities up to 120 feet and smaller support equipment, no job is too large or too small to support.

Multi-spindle, long-bed gantry machines enable high-precision parts up to 120 feet long.

Prototype-through-production capabilities

What starts out as a brilliant idea becomes reality with our prototype design, development, performance testing, and 3D-printing processes where necessary. Our customers can hold an advanced concept in their hand and follow it all the way through to production.

Our design-for-manufacturability process means the concurrent engineering of the product and its manufacturing process ensure quicker time-to-market by shortening product development, containing development costs, and ensuring smoother transitions throughout the production life cycle.

Validation and inspection
Inspection of part and validation

We adhere to stringent processes that monitor all aspects of production. ARCH employs the latest inspection technologies for the validation and inspection of manufactured parts and assemblies. We utilize laser trackers, portable 3D measuring arms, and coordinate measuring machines (CMMs) to ensure every feature meets or exceeds customer specifications. Inspection software is used to prepare first article inspection (FAI) documentation, collect FAI data, and prepare FAI reports.

Assemblies and vertical integration
Structural assembly

We offer extensive complementary capabilities that enable us to be a vertically integrated, one-stop choice for your complex structural component manufacturing needs. ARCH is fully equipped to provide a wide array of structural assemblies for aerospace and defense OEMs, from benchtop subassemblies to large aircraft structural assemblies. Our sheet metal capabilities allow us to manufacture and support major complex structural assemblies.

ARCH provides advanced supply chain management services, including raw materials, parts cleaning, identification, kitting, and packaging needs. We can add value to your parts outsourcing by performing additional processes, including assembly of precision components, microscopic deburring, plus installation of components such as bearings, snap-rings, thread inserts, and more.
