CNC Applications and Industries Examples

CNC machining in prototype production is not confined to a specific sector; its applications are diverse and widespread. From crafting aircraft components to surgical instruments, CNC applications finds utility across various industries. Below are some CNC applications that benefit from the purposes of CNC machining:

Aerospace Industry

With a longstanding association, the aerospace industry relies on CNC machining for the precision machining of metal aircraft components. This precision is crucial for safety-critical applications, and the versatility of engineering metals compatible with CNC provides ample choices. Notable CNC applications include engine mounts, fuel flow components, landing gear components, and fuel access panels.

Automotive Industry

The automotive sector regularly employs CNC milling machines for prototyping and production. CNC machining transforms extruded metal into components such as cylinder blocks, gearboxes, valves, axles, and more. Additionally, plastics can be CNC machined for items like dashboard panels and gas gauges. The speed of CNC processes enables the creation of custom and replacement parts with minimal turnaround times.

Consumer Electronics

CNC machining plays a pivotal role in prototyping and producing consumer electronics, including laptops and smartphones. For instance, the chassis of an Apple MacBook is crafted through CNC machining of extruded aluminum, followed by anodization. In the electronics industry, CNC machining is instrumental in creating PCBs, housings, jigs, fixtures, and various CNC applications components.

Defense Industry

The military sector turns to CNC machining for prototyping durable and reliable parts designed to withstand wear and tear with minimal upkeep. CNC machining in the defense industry is beneficial for creating on-demand replacement parts and upgraded components, particularly in areas overlapping with aerospace and electronics. This capability proves valuable for parts requiring constant innovation and security.

Healthcare Sector

CNC machining is applied to medically safe materials in the healthcare industry, finding use in the production of one-off custom parts. The tight tolerances provided by CNC machining are essential for achieving high-performance machined medical components, including surgical instruments, electronic enclosures, orthotics, and implants and other CNC applications.

Oil & Gas Industry

The oil and gas industry, known for safety-critical applications, relies on CNC lathe machining for precise and reliable parts like pistons, cylinders, rods, pins, and valves. These components, essential for pipelines and refineries, often necessitate corrosion-resistant machinable metals such as Aluminum 5052 and may be required in specific quantities tailored to the industry’s needs.


Manufacturability of CNC Machining

Another approach to categorizing the CNC applications is by exploring its manufacturing possibilities and uses. CNC machining proves highly beneficial in various areas:

Rapid Prototyping

The autonomy and efficiency of CNC machines contribute to fast turnarounds. Once a digital design is finalized, machinists can promptly transmit it to the CNC machine, resulting in the rapid fabrication of prototypes. CNC machining, particularly with the application of CNC lathe, remains robust regardless of the chosen method for machining the final component. Machined prototypes meet high standards and closely resemble the end-use parts.

Volume Production

The precision of CNC machining extends to creating high-quality components for end-use applications. The material versatility inherent in this process allows for the fabrication of a diverse range of parts. Overall, CNC machining emerges as a cost-effective manufacturing process suitable for various projects. Irrespective of size or complexity, numerous industries employ this manufacturing method to produce functional final parts.


Beyond its role as a direct manufacturing process, CNC machining serves as an indirect manufacturing process that aids procedures like injection molding. It excels in machining various steels and robust aluminum, producing parts such as metal molds that can be filled with other materials to generate products in large quantities.

Hybrid Manufacturing

CNC machining need not operate independently of other manufacturing processes. Combining it with methods like 3D printing or metal casting can yield superior parts and products. For instance, CNC machining can be employed to add features such as holes and threads to a printed or cast part.

Electrical Discharge Machining (EDM)

CNC automation facilitates electrical discharge machining (EDM) in two distinct ways. Vertical EDM, which requires electrodes with a similar shape and size as the cavity to be carved out, is made possible by CNC. Another type, Wire EDM, aids in creating punch and die combinations for different die sets used in metal and plastic fabrication.
