CNC Machining for Aerospace

Aerospace CNC Machining Services in Canada — AS9100D Certified, Built to Fly

Aerospace CNC Machining for Aerospace services are essential for the manufacturing and maintenance of aircraft and space vehicles. CNC machining for aerospace industry involves the use of computer numerical control (CNC) machines to create precise and accurate parts for aerospace applications. CNC machining is a process that involves the use of computer-controlled machines to cut, drill, and mill various materials such as metal, plastic, and composite materials.

The aerospace industry has stringent requirements for the quality and reliability of its parts, and CNC machining allows manufacturers to meet these high standards. CNC machines are highly precise and can produce parts with tight tolerances, making them ideal for aerospace applications. They are also capable of producing complex shapes and geometries, which is important for the design of modern aircraft and space vehicles.

Aerospace CNC Machining Services — Parts, Materials & Key Benefits

Aerospace CNC machining services can be used to manufacture a wide range of parts, including structural components, engine parts, and avionics components. They are also used for repair and maintenance of existing aircraft, allowing manufacturers to replace damaged or worn-out parts with precision-machined replacements.

One of the Benefits of CNC Machining for Aerospace is the ability to produce parts in large quantities quickly and efficiently. This is important in the aerospace industry where the demand for parts can be high, and the need for quick turnaround times is critical. CNC machining can also be done using various materials, including aluminum, titanium, and composite materials, allowing manufacturers to choose the best material for each application.

Why Aerospace CNC Machining Demands a Different Standard

Aerospace is not a normal manufacturing environment. The tolerances are tighter. The materials are harder. The documentation requirements are more extensive. And the consequences of a non-conforming part reaching an aircraft are severe — reputationally, financially, and in the worst case, physically.

Selecting a CNC machining supplier for aerospace work is not simply a price-per-part decision. It is a supply chain risk decision. Your machining partner’s quality system, certification status, material handling practices, inspection capability, and FAI processes all become part of your program’s risk profile.

Promark has been making that risk profile smaller for Canadian aerospace customers for over 50 years

Importance of Quality Control in Aerospace CNC Machining

In addition to the manufacturing of parts, aerospace CNC machining services also include quality control measures to ensure that each part meets the required specifications. This may include inspections and testing to ensure that the parts meet the necessary tolerances and performance standards.

Overall, aerospace CNC machining services are a critical component of the aerospace industry, enabling the production of high-quality, reliable parts for aircraft and space vehicles. With their precision and efficiency, CNC machines are essential for the continued advancement of the aerospace industry.

Our Aerospace CNC Machining Certifications

AS9100D Certified

AS9100D is the international quality management standard for the aviation, space, and defence industries. It builds on ISO 9001 and adds requirements specific to aerospace: risk management, configuration control, first article inspection, key characteristics, and counterfeit parts prevention, among others.

Promark holds current AS9100D certification. This means:

Our quality management system has been independently audited and verified against the most stringent aerospace manufacturing standard
Our processes for material control, non-conformance management, corrective action, and record retention meet aerospace program requirements
Your supplier qualification team can check off AS9100D compliance — and we can support your audit process with full documentation access

ISO 9001:2015 Certified

Our ISO 9001:2015 certification underpins the broader quality system that AS9100D builds on. Every machining process at Promark operates within a documented, controlled, and continuously audited quality framework.

Controlled Goods Program (CGP) Participant

Promark participates in Canada’s Controlled Goods Program, which governs the examination, possession, and transfer of controlled goods under the Defence Production Act. For defence and dual-use aerospace programs, this means Promark can handle designated controlled goods without triggering security screening barriers at your end.

Aerospace CNC Machining Capabilities

We machine a comprehensive range of aerospace structural, mechanical, and system components across multiple processes and materials:

Precision CNC Milling

Multi-axis milling for complex aerospace geometries – pockets, contours, compound angles, and thin-wall structures. Our machining centres handle everything from small precision brackets to larger structural frames with tight positional and profile tolerances.

CNC Turning & Turning-Milling

Precision turned components for actuation, fluid systems, and engine-adjacent applications. Turning-milling capability allows complex rotational parts with off-centre features to be completed in a single setup – reducing handling, fixturing errors, and lead time.

Drilling, Boring & Reaming

Precision hole-making for fastener interfaces, bearing bores, and hydraulic passages. We hold tight diameter, perpendicularity, and positional tolerances across multi-hole patterns that must align with mating assemblies.

EDM (Electrical Discharge Machining)

For features that conventional cutting tools cannot access – internal profiles, fine slots, and hard-material forms – EDM provides the precision required without inducing the mechanical stress of conventional machining.

Serving Canada’s Aerospace Supply Chain

Canada’s aerospace sector spans the full value chain — from OEMs and Tier 1 manufacturers to parts producers, MRO providers, and emerging UAV innovators — with major clusters in Ontario and Quebec. Promark is strategically located in Toronto to serve this supply chain directly.

Promark is part of this ecosystem, with the certifications and capabilities to qualify for Tier 1 and Tier 2 supplier programs.

We machine components for programs and platforms across:

Business jets — Structural brackets, interior hardware, system components for business aviation programs
Regional and commercial aircraft — Airframe brackets, control system hardware, structural inserts
Helicopter & rotorcraft — Precision components for rotor systems, drivetrains, and airframe structures
Defence & military aviation — Components for fixed-wing and rotary-wing military platforms under Controlled Goods Program compliance
Space and satellite systems — Tight-tolerance structural and mechanical components for space applications
Ground support equipment (GSE) — Tooling, jigs, fixtures, and support equipment for aerospace MRO operations

Your Aerospace CNC Machining Partner in Canada

The Canadian aerospace supply chain demands machining partners with the right certifications, the right equipment, and the right culture of quality. Promark Tool and Manufacturing has been meeting that standard for over 50 years from our Toronto, Ontario facility – AS9100D certified, CGP registered, and ready to support your program from first article through production.
