Aerospace precision parts CNC machining can take on complex tasks that demand accuracy. Working with GN Corporations ensures your aerospace parts are of the highest quality and ready to work.

Benefits of Using CNC Machining for Aerospace Parts

  • Superior Performance: Failure in aerospace components can be devastating, which is why the industry is highly regulated and scrutinized. Parts must meet stringent performance, tolerance, and dimensional requirements. CNC machining makes these attributes possible without increasing costs.


  • Lightweight: Aerospace parts must be light so the aircraft can take off and reduce fuel consumption while in flight. CNC aerospace machining can produce thin-walled components and work with necessary alloys to produce strong yet lightweight components ready for flight.


  • High Efficiency: CNC machining leverages automation to achieve higher per-part speeds and shorten overall production cycles. GN’s Industry 4.0 processes leverage machine learning and automation throughout our workflows to save time without sacrificing quality.


  • Reliable Precision: One primary reason why CNC machining aerospace parts has become so popular is because of the need for precision while tackling complex designs. CNC provides better accuracy and control to minimize defects and produce high-quality components.



  • Affordability: Per-part costs can be decreased when CNC machining is leveraged for rapid production. Manufacturers can reduce waste, labour hours, and rework due to the combination of automation and precision. Reducing defects creates significant savings for the entire batch.

Aerospace CNC Machining Applications in Aviation and Spaceflight

CNC machining is widely used throughout aviation, aerospace, and spaceflight to manufacture components that demand precision and durability. Common use cases include valve components, electrical connectors, filter bodies, and oxygen generation components. Any faults in these areas can be devastating, leading companies to use CNC precision machining.

Materials for Aerospace Machined Parts

  • Aluminum Alloy Series 2xxx: This series of alloys is combined with copper to create a high-strength and workable alloy. Precision aerospace CNC machining parts manufacturers use this alloy for machined parts such as fuselage structures and airplane wings.
  • Aluminum Alloy Series 6xxx: By using magnesium and silicon, this alloy series is one of the most versatile aluminum alloys. The material provides better corrosion resistance, formability, and strength compared to some other options. Series 6xxx is widely utilized throughout many industries.
  • Aluminum Alloy Series 7xxx: Series 7xxx focuses on using zinc as the primary alloying element and can also include magnesium, copper, or chromium. The resulting alloy is strong and durable, making it widely used in defense and aerospace.

Our CNC Machining Capabilities

Unique CNC machining capabilities are why aerospace parts CNC machining manufacturing is one of the top methods in the industry. Multi-axis machines are at the core of this method.

Some of the most common CNC machines are:

5-Axis CNC Milling

The cornerstone of CNC machining is the 5-Axis milling machine.  Our 5 axis CNC machine is capable of manufacturing polyhedrons and complex structural parts in a single operation.

9-Axis CNC Mill and Turn

Choosing the 9-Axis milling machine allows your CNC partner to manufacture more complex shapes, which is often necessary for the highly specialized components in the aerospace industry.

5 Axis Water Jet Cutters

5-Axis Water Jet Cutters & Wire EDM

Similar to the standard 5-Axis milling machine, this version uses water jet cutters or wires to take on different materials without jeopardizing integrity with cuts.
