5 Main Industries that Use CNC Machines - Avanti Engineering

CNC, or computer numerical control, machining creates high volume precision turned parts and other parts for dozens of industries. CNC machining is ideal for companies looking for parts that are accurately designed and created using computers. Thanks to advancements of both the machines and computers, the process allows for intricate designs that can be consistently recreated with minimal variance.

Industries that Use CNC Machines

Many industries utilize CNC machines to create high volume precision turned parts and other parts. Let’s take a look at some of the most common applications these parts are required for:

Electronics
There is a trend of miniaturization within the consumer electronics industry. Components are continually becoming smaller, yet more powerful than before. The parts need to be compact and lightweight as well. Small scale CNC machining is perfect for handling the specialized materials that are needed for this. Examples of products created for electronics through CNC machines are:

  • Electrical Insulation
  • Housings for amplifiers
  • Heat sinks
  • Shielding against radio frequency interference

Medical
The medical field utilizes customized products that fit the needs of patients. Since most devices used in medical practices are disposable, these businesses need both high volume and precision. There are many types of CNC machines that work well for creating parts in this industry. Products made for medical businesses using CNC machines include:

  • Research equipment
  • Orthotic devices
  • Various types of implants
  • MRI machines

Aerospace
The aerospace industry has a vast need for repeatability and high accuracy. To ensure safety and compliance of critical parts, tolerances of just ±0. are required. CNC machines are the perfect choice for this, as they are extremely precise. CNC machining services are great for creating everything from complicated bearing housings to high tolerance spacers. Here are some other aerospace parts made with CNC machines:

  • Antennae
  • Airfoils
  • Bushings
  • Parts for landing gear

Oil & Gas
Drilling rigs and refineries use large machines made with machined parts to ensure they fit perfectly together. If the fit isn’t precise, cylinders may not fill, pistons won’t create the right amount of pressure, and valves may leak. Hence, petrochemical companies use parts that have been CNC machined to ensure they fit exactly as needed. The oil and gas industry use parts created by CNC machines for rigs, refineries, and pipelines. Some examples are these components are:

  • Drill bits
  • Rods
  • Pistons
  • Valves

Marine
The marine industry is another example of businesses that rely heavily on parts created by CNC machining services. Just like airplanes, watercraft rely on highly-precise parts to keep them running and afloat. Not to mention all of the marine equipment that goes along with watercraft, such as underwater sensors, communication equipment, and more. Hence, CNC companies create many parts for boats, including:

  • Propellers
  • Components for the engine
  • Insulating cases
  • Prototype molds

Importance of CNC Parts in the Manufacturing Industry

The manufacturing industry has come a long way from its traditional manual machining techniques. CNC technology has greatly improved production efficiency, accuracy, and consistency in the industry. This blog will cover the importance of CNC parts in the manufacturing industry.

CNC machines are computer-controlled machines that use a program to produce parts with high precision and repeatability. It means that production time gets reduced and the cost of production is lowered, resulting in a higher-quality end product. 

The accuracy and consistency of CNC machining also mean less room for human error, making the production process much more reliable.

CNC machine market value rose from $70 billion in to a projected $111 billion by , reflecting 6.8% growth.

The parts outperform traditional ones, as failure in critical components can have severe consequences.

CNC machines are the same as traditional ones but have the added benefit of computer control and multi-axis capabilities. Depending on the operations required, different types of CNC machines get used in the industry. For example, a CNC lathe can perform machining operations involving cuts in the circular direction. 

Reasons Why CNC Part Machining is Gaining Popularity 

CNC machines provide greater accuracy for manufacturers. It allows the manufacturers to produce identical components with the highest precision levels. CNC components have better tolerances overall, and the repeatability is at the next level. The performance of the human operator is affected due to external factors, which in the long term comprise the quality. 

CNC parts are popular in aerospace and defense due to improved tolerances and precision in machined parts.
