What Is Aerospace CNC Machining?

The global CNC market was worth nearly $82 billion in 2020 and is expected to grow to $128 billion by 2028. As more and more industries realize the multiple benefits of this production method, aerospace companies continue to be among the largest buyers. Salco Global is one of the leading players in the market of aerospace components manufacturers. In this article, we provide a comprehensive guide to aerospace machining.


The assembly, repair, and maintenance of aircraft and space shuttles are done with the help of CNC machining. Several aerospace companies use CNC machining in aerospace for kits, components, and assemblies needed for their end products and services.


CNC machining uses machine-powered cutting tools to produce products using subtractive machining techniques. By removing parts of the workpiece, complex designs can be created on a large scale and with high precision. Computer-aided design software controls all inputs and machine-driven processes, reducing human error to zero.


All aircraft parts, such as bushings, hinges, brackets, and other custom parts, must be made from high-quality materials. This is the only way to ensure that aircraft parts will function properly without posing a hazard. In the aerospace industry, titanium and Kovar are the most commonly used metals. However, materials such as aluminum, stainless steel, copper, bronze, and some plastics can also be used.

What are the benefits of aerospace machined components?


  • The technology is highly accurate and precise
  • Due to automation processes, there is no chance for human error
  • Possibility of constructing complex geometric shapes
  • In addition to high precision, aerospace parts CNC machining enables fast prototyping and quick production in large numbers.


Several aspects must be considered when manufacturing aerospace parts and structures, whether for everyday aviation, space flight, or defense. For spacecraft, in particular, longevity must be considered in addition to precision – aircraft are often in service for long periods, even years. 


Aircraft are assembled on an international scale, for example, more than 6 million parts of Boeing’s largest aircraft (747-8) come from countries such as China, Germany, and Australia. In other words, every single part must be extremely precise and clean, and this is where aerospace machining companies play a crucial role.
