5 Reasons Why CNC Machining is Preferred to Traditional Machining


Over the years, the low-volume manufacturing industry has experienced steady and consistent growth. As most processes continue to become more sophisticated and demand more automation, CNC machining has been steadily replacing the use of conventional machining in the industry for a number of reasons.

Today, we take a look at 5 advantages that the CNC machining process holds over the traditional machining approach. Let’s get right into it!

What is CNC machining?

CNC machining refers to “Computer Numerical Control”. In the simplest way possible, it is a process employed in the manufacturing sector involving the use of computers to control machine tools. The process is almost 100 percent automated and can be used with tools such as grinders, routers, lathes, mills and more.

Why is CNC machining preferred to traditional machining?

Due to the technique, volume and sophistication of most manufacturing processes, there has always been a growing need for the adoption of methods that make manufacturing faster, better and more accurate. Both CNC and traditional machining have the same goal of producing quality machined parts, however, one does it better. Here are 5 reasons why CNC machining is preferred to traditional machining.

1. Lower labour costs

Arguably the major differences between CNC and conventional machining approaches, CNC machining methods boasts of 90 percent automation which can significantly reduce your overheads.

When it comes to traditional machining, every machine requires that you have a dedicated expert with in-depth knowledge of how the machine operates. With CNC however, the machining is majorly controlled by a program that requires significantly lesser human input after it has been set up and data-fed. Also, CNC does not require advanced training and reduces the chances of errors and workplace causalities significantly.

2. Higher quality output

Whether being utilized to make a dozen of products or engaged for hundreds of thousands of parts, CNC machining are able to produce high quality over larger quantities of machined parts. Since they are fairly resistant to wear, tear and fatigue, CNC machining processes can run all through the day, requiring minimal maintenance from time to time.

CNC machines are also accompanied by automated cooling systems that reduce the tendency of heat damage and ensure that both small and large quantities are produced with the highest-possible quality.

3. Excellent replication performance

When running replicative processes or producing the same machined parts in bulk, traditional machining will usually require a skilled operator. The operator will be saddled with the responsibility of manually placing the tool at various steps of the machining process. This would take time and effort. Even more, due to the inconsistency that can be expected from human input, variations in the output are to be expected. CNC machining on the other hand is designed to master key factors such as velocity and positioning. Thus, CNC machines can produce thousands of parts, all 100 percent identical while taking considerably lesser time.

4. No prototypes required

Prototyping is very important in both high and low volume manufacturing processes. This is because manufacturers need to simulate their designs and evaluate feasibility and functionality before embarking on large scale production. In the case of traditional machining, manufacturers will need to develop prototypes and test-run them to ensure that they work properly. When these processes are done manually, it could take weeks or even months to get results. With CNC machining on the other hand, manufacturers can use software to input their designs and see a realistic view of what the output would look like, thus eliminating the need and time taken for prototypes to be perfected.

5. Diverse application

The diversity of the CNC machining method is also one of the biggest advantages that it holds over conventional machining. CNC machining can be used for a wide array of materials including metals, steel, foam, plastics or wood. Traditional machining on the other hand may encounter difficulties when dealing with certain types of materials.

Bottom line

CNC machining holds a plethora of advantages over traditional machining in both high and low-volume manufacturing.
