Summary. Discover the advantages of CNC machining vs manual machining in the manufacturing industry. PT Engineers, experts in CNC machining services, explore the benefits of precision, speed, cost-effectiveness, flexibility, safety, and consistency offered by CNC technology.


Computer Numerical Control (CNC) machining is a modern approach to manufacturing that relies on computer software to control machinery. There are many advantages of CNC machining and as a result, this technology has revolutionised the manufacturing industry. PT Engineers are highly experienced CNC machining manufacturers, offering a range of CNC machining services to businesses across the West Midlands and beyond. In this blog, we will explore CNC machining vs manual machining, and how each method can affect the manufacturing process.

So what makes CNC machining better than manual machining?

Precision and Accuracy

Using advanced technology, CNC machines are incredibly precise and accurate, offering consistent results every time. With CNC machining, the cutting tools are guided by computer software. As a result, we can control the movement of the machinery to the micro-metre level. This means CNC machining can work with the most detailed and intricate projects. In contrast, manual machining relies on the skill and expertise of the operator, which can lead to human error, resulting in less accurate results. This limits the type of shapes and sizes that can be worked on through manual machining.

Faster Production

Another key advantage of CNC machining is that CNC machines can produce parts faster than manual machining. This is because they don’t require the same level of human intervention. Once the design is programmed into the computer software, the machine can operate continuously, producing parts without interruption. This allows for higher production volumes and shorter lead times. Therefore, making it easier for companies like PT Engineers to meet tight deadlines.

Reduced Labour Costs

CNC machining requires less labour than manual machining, making it more cost-effective for businesses. CNC machines can operate for extended periods without needing to take breaks, reducing the need for multiple operators. In contrast, manual machining requires skilled operators to work on the machines for extended periods, leading to higher labour costs. High labour costs often lead to higher prices overall, which is why CNC machining can often be the more cost-effective way to manufacture too.


CNC machines offer greater flexibility than manual machining because they can produce a wide range of parts with minimal retooling. With manual machining, each part requires specialised tooling, which can be time-consuming and expensive to set up. On the other hand, CNC machines can quickly change tools and adapt to new designs. This makes them ideal for prototyping and low-volume production runs.

Improved Safety

CNC machines are safer to operate than manual machines because they are fully automated and require less human intervention. This reduces the risk of accidents and injuries that can occur with manual machining, where operators are required to work in close proximity to moving machinery.


Alongside the accuracy advantages of CNC machining, CNC machining also provides consistency in parts production, making it easier to create identical parts. This level of consistency can be difficult to achieve with manual machining, where variations in operator technique can lead to slight variations in the final product.
