CNC machining uses span a wide range of industries and products. CNC machining is often one of the most viable solutions for companies that need to create small to medium-sized parts quickly and efficiently. Here are some of the most common CNC machining applications: but before that, a thing or two about CNC machining.

CNC Machining Technology

CNC machining technology is a form of computer-aided manufacturing (CAM). CAM software is used to prepare a model created in CAD for machining by determining the tool paths needed to produce the desired geometry. CNC machines are then used to follow these paths and create the required parts or products.

CNC machines typically create parts from metals, plastics, wood, composites, or even foam. They can create a wide variety of shapes and sizes, and they can be used to create both simple and complex parts. Below, we take a look at some of the CNC machining uses today.

CNC Machining Uses

The CNC machining industry is vast, with applications in virtually every manufacturing sector. Besides manufacturing, the technology is also popular in the jewelry, woodworking, and engraving industries. Here, we prepared a list of CNC machining uses and applications.

  1. CNC Machining for Medical Industry

The medical industry relies on CNC machining to create various parts and products. These parts must meet strict standards for quality and performance, which makes CNC machining a viable solution. Some common medical industry CNC machining applications include:

  • Creating implants
  •  Machining dental prosthetics
  •  Manufacturing surgical instruments
  •  Building medical devices

CNC machining for medical industry products will continue to grow as the demand for new and innovative medical treatments increases.

  1. CNC Machining for Automotive Industry

The automotive industry is another primary example of the most popular CNC machining uses. CNC machines are used to create a wide variety of parts for cars, trucks, and other vehicles. Some common CNC machining applications in the automotive world are:

  • Creating engine parts
  •  Machining transmission components
  •  Building suspension systems
  •  Constructing exhaust systems

CNC machining automotive parts offer a number of advantages, including the ability to create complex shapes and designs and the ability to mass produce parts quickly and efficiently.

  1. CNC Machining for Aerospace Parts

The aerospace industry also relies heavily on CNC machining technology. CNC machines are used to create both small and large parts for airplanes, helicopters, and other aircraft. With aerospace parts CNC machining, manufacturing is fast and highly precise, with higher. Some typical aerospace applications of CNC machining include:

  • Machining parts for aircraft engines
  •  Building fuselage components
  •  Constructing wings and flight surfaces
  •  Creating landing gear assemblies

CNC machining is a good solution for the aerospace industry because it allows for the creation of complex shapes. You can also mass-produce parts quickly and efficiently. Another major advantage of using CNC machining for aerospace parts is the tighter tolerances that can be achieved.

  1. CNC Machining for Electrical Parts

One of the major CNC machining uses is in the manufacture of electrical parts. Different CNC machining techniques are used, including milling and turning, to create a wide variety of electrical parts. CNC machining examples when it comes to electrical parts are listed below.

  • Machining parts for electrical motors
  •  Building generator components
  •  Creating switchgear assemblies
  •  Drilling PCBs and other machining processes

Using CNC machining for electrical parts manufacturing ensures not only a high degree of accuracy and repeatability but also a consistent level of quality. It’s also a fast method to produce parts in large quantities.

  1. CNC Machining for Wood Carving

In addition to the above CNC machining uses where metal and plastic are mostly the material of choice, this computer-controlled process can also be used for wood carving. Different types of bits and routers are used to create detailed wood carvings, sculptures, and other products. The following are examples of activities when using CNC machining for wood carving projects.

  • Carving architectural details
  •  Creating wood furniture
  •  Machining musical instruments
  •  Building wooden toys

CNC machining wood produces parts and products that are extremely accurate and have a very high level of detail. CNC machined wood will also be very consistent in quality, which is important for any woodworking project.

  1. CNC Machining for Oil and Gas Industry

The oil and gas industry is another sector that relies heavily on CNC machining. A wide variety of parts and components are required for the construction and maintenance of oil rigs, pipelines, and other energy infrastructure. Some common CNC machining applications in the oil and gas industry include:

  • Machining parts for oil rigs
  •  Building pipeline components
  •  Creating valve assemblies

The oil and gas industry is a demanding sector that requires parts and components that can fit and withstand a wide range of conditions. CNC machining, with its high degree of accuracy and repeatability, offers many benefits when used.

  1. CNC Machining for Home Use

The CNC machine isn’t just a commercial tool; it can also be used for a variety of home projects. If you’re a keen DIY-er or hobbyist, then you may be surprised at just how useful a CNC machine can be. Examples of CNC machining projects that you could do at home include:

  • Making custom furniture
  •  Carving woodwork details
  •  Creating metalwork sculptures
  •  Designing and making jewelry
  •  Making household items such as door handles and light fixtures

A wide range of CNC machining equipment is now available that is designed specifically for the home user. These range from small, desktop CNC machining devices for small projects to larger, more industrial machines that are capable of tackling bigger projects.

CNC Machining Services

Many companies (or individuals) looking to produce parts or prototypes using CNC technology may need help to invest in the expensive machinery required. This is where CNC machining services come in. So some businesses offer CNC machining as a way to outsource parts production.

With the many CNC machining uses, the advantages of using these services include:

Cost: Outsourcing parts production may be more cost-effective than investing in machinery, especially if you are not involved in bulk production.

Expertise: Machining service businesses may have the knowledge and experience to produce high-quality parts.

Access to Machinery: A CNC machining company will have a wide range of machines, which gives it the ability to produce parts quickly and efficiently.

Alternatively, and given the versatility of the technology, investing in a CNC machining business could be a lucrative opportunity. That could involve setting up a workshop and acquiring several CNC machines. Either way, CNC is a technology with many applications and benefits.


CNC machining uses cutting across different sectors for a reason. In essence, the versatility, accuracy, and other attributes make the CNC process an ideal solution for a wide variety of uses in many different industries. Whether used on its own or as part of a larger manufacturing process, CNC machining can provide parts and products that meet the highest standards of quality and performance.
