The Importance of CNC Machining in the Aerospace Field

Under the backdrop of innovative development, the global aerospace industry, which exceeds 100 billion dollars, continuously stands at the forefront of new manufacturing practices and cutting-edge technology. Aerospace CNC machining undoubtedly plays a crucial role within this sphere. Below, we will start with a definition of aerospace CNC machining, detailing the technology and common materials used, to highlight its importance in the aerospace field.

Definition of Aerospace CNC Machining

Aerospace CNC machining is a process that utilizes computer numerical control (CNC) technology to precisely manufacture and process components and parts within the aerospace sector. During this process, pre-written precise programs control the movement of the machine tools and the cutting paths of the tools, transforming raw materials into parts with specific shapes, dimensions, and precision requirements.

Aerospace CNC machining encompasses various machining methods such as milling, turning, drilling, and grinding, and can handle a range of high-performance materials, including but not limited to titanium alloys, superalloys, and high-strength aluminum alloys.

These components typically feature complex geometries, strict tolerance requirements, and high reliability standards to meet the performance and safety demands of aerospace vehicles in extreme environments.

For example, key components of aircraft engines and structural parts of spacecraft rely on aerospace CNC machining to achieve high quality and precision manufacturing. Ward Precision Technology strictly adheres to rigorous industry standards, continuously driving innovation and development in aerospace CNC machining processes. Utilizing aviation-grade metals or plastics, they can produce prototypes and parts for the aerospace industry through CNC machining.

Aerospace CNC Machining Technology

3-Axis CNC Machining

3-axis CNC machining can meet most of the requirements in the aerospace industry. It is a reliable workhorse for manufacturing components, capable of precisely machining aerospace parts with minimal dust and noise, and is generally easy to use. It can be used with various components and materials including carbon fiber, aluminum, and stainless steel. One of the significant advantages of 3-axis machining is its ability to produce parts at very high speeds, and it can machine parts on very flat planes.

5-Axis CNC Machining

5-axis CNC machining can produce complex aircraft components, allowing for milling, drilling, and movement along X, Y, Z, and rotational planes. These operations can be performed simultaneously without the need for fixture or reconfiguration. Parts with complex geometries or partially hollow structures are valuable in the aircraft industry because they help make products lighter without compromising their quality or performance.

Common Aerospace CNC Machining Materials

High-Performance Plastics

Although metal components have more uses in the functional structure of airplanes, many internal components are still made of polymer materials. Compared to metals, these polymer materials are much lighter and can be used to produce interior wall panels, wiring ducts, aircraft doors, bearings, and more. These are aviation-grade plastics that are strong, lightweight, and meet fire safety standards. CNC machining produces complex parts that are sturdy and lightweight, suitable for the aerospace industry. For example, PEEK and other high-performance polymers can be used to manufacture these components.

Light Metals

Materials used in aerospace CNC machining must have two specific characteristics: strength and weight. Although steel and other strong metals have significant power, they are not the best materials for most components due to their weight, which leads to higher fuel consumption and costs for airplanes. Therefore, the aerospace industry considers using strong and lightweight metals such as titanium and aluminum alloys. Titanium is about 50% lighter than steel and about 30% stronger, with excellent corrosion and high-temperature resistance properties, making titanium alloy CNC machining ideal for external and operational aircraft parts. Aluminum is lighter than titanium but only about half as durable. However, this highly machinable metal is less expensive than titanium, making it also suitable for various aerospace parts.

In summary, aerospace CNC machining technology has become a powerful driving force for continuous progress in the aerospace field due to its exceptional precision, efficiency, and reliability. Looking forward, with continuous technological innovation and increasing market demand, aerospace CNC machining will undoubtedly play a more critical and central role in the aerospace industry, helping humanity to explore and advance into broader cosmic space.
