CNC Precision Engineering an All-Inclusive Guide

Manufacturers of precision components and parts need to know the basics about CNC Precision Engineering. If you are one, this article is for you!

An Introduction to CNC Precision Engineering

The history of CNC precision engineering can be traced back to the 1940s when it was popularly known as “precision machine tools”. It is an automated machining technology used in manufacturing. The name changed around 1960 due to technological advancements which made computer numerical control (CNC) possible. The components and parts produced by this technology are very precise and accurate.

CNC Precision Engineering Process

The process involves the three major steps of programming, machining, and inspection. The programming is done by a software engineer who designs computer programs for manufacturing machines to produce specific components or parts with utmost precision. CNC milling, turning, wire-cutting are some common examples in this process. The next step involves the actual machining in which a machine tool is used to produce components with accuracy and precision through computer numerical control (CNC). Lastly, an inspection of parts at every stage of development plays an important role in achieving optimum quality output for this type of manufacturing technology.

Types of Machinery Used

The equipment used for this type of manufacturing is expensive. However, they are highly efficient and time saving in the long run. Some common equipment used include lathes, milling machines, wire-cut EDM (Electrical Discharge Machines), surface grinders among others.

Who Uses CNC Precision Engineering Technology?

Various industries use this type of manufacturing technology to produce components and parts with high accuracy, precision, and efficiency. Industries such as the defense industry require highly accurate machine tools for production of airplane propellers which are vital in aircraft. The automobile industry is another major user especially when it comes to high-performance vehicles. Precision turning, milling and lathe cutting are some of the common machining processes involved in this industry.

Why CNC Precision Engineering Technology?

Companies using CNC precision engineering technology have increased their production capacity by 30-40% due to high manual labor costs which make it difficult for them to compete with other global companies that are producing at cheaper rates. The equipment used in this technology are efficient, accurate and very precise which makes the products produced much better than other alternatives that use manual labor or automation technologies.

Some benefits associated with this technology include shorter lead time, better accuracy and precision of parts, reduced manufacturing cost among others. These machines are used in mass production because they help save a lot of time as compared to traditional machining equipment. This is also an environmental-friendly technology due to its efficient nature.

What Are the Challenges of CNC Precision Engineering?

Although CNC precision engineering technology is beneficial, it comes with a downside. It requires high initial cost to buy equipment and set up the manufacturing plant. In addition, operators of this machinery must be highly skilled as they deal with complex machine tools.

What Are the Applications of CNC Precision Engineering?

This technology has been applied in various industries such as automotive, defense, aerospace, mechanics among others. It is also used in the production of high precision components and parts which are mostly exported to other countries for manufacturing purposes.


CNC Precision Engineering has revolutionized machining technology over the years due to its efficient nature and precise outcomes. Manufacturers have greatly benefited from this innovation because it reduces their cost, time and also increases productivity.
