CNC machining is a subtractive manufacturing method. It features a wide range of processes like CNC milling, drilling, and lathing. The process can also be done using a wide range of CNC machines. Regardless, the characteristics of CNC machined parts remain constant in each case. This post will be looking into the various machined part characteristics.

Characteristics of CNC machined parts

Below are some basic elements of all CNC machined parts:

1. Adaptability and flexibility

One of the primary characteristics of CNC machined parts is that they are highly flexible and adaptable. This is because the manufacturing technique can be used to manufacture a wide range of products in various industries. The quality of the products also makes them highly adaptable.

2. High precision and impeccable quality

CNC machined products also boast high precision and quality. This is because CNC machining tools work using CAM instructions. These instructions eliminate the chances of errors that manual interventions would trigger. Additionally, during the CAD model design phase of the process, multiple measurements are taken. This is done to ensure high precision and rigidity. It also ensures the dimensional precision of the CNC machined parts.

Additionally, compensation technology can be applied to enhance the precision of the process. This is especially the case with 5-axis CNC machines. They allow you to achieve intricate design elements with high precision.

3. Good surface quality

CNC machined parts also boast impeccable surface qualities. Below are some of these qualities;

  • Wear resistance– the parts are resistant to wear since they are perfectly manufactured. There aren’t any flaws or errors in the manufacturing process that could result in issues in the long run. However, it is worth mentioning that the wear resistance of the product can be influenced by the type of material used. It also depends on the type of CNC machining technique and machine applied.
  • Corrosion resistance– the corrosion resistance of material usually depends on the quality of the surface finish. Therefore, the higher the surface finish quality, the better the corrosion resistance of the part. CNC machining, especially 5-axis CNC machining, helps ensure high surface finish quality.

However, it is worth noting that the corrosion resistance also depends on the type of metal used in the process. The parts can also be subjected to finishing techniques to enhance their resistance to corrosion and rust. Additionally, the manufacturing quality influences the ability of the part to take the finishing product.

  • No surface interruptions– CNC machining prevents issues like cracks, scratches, and ridges, which are known as surface interruptions. This is because the process is mainly computer-controlled and less prone to human error.

4. Durability

Another characteristic of CNC machined parts is durability. These products are designed with quality and precision in mind. The materials used in the manufacturing process are also high-quality. For this reason, CNC machined parts are highly durable.

Conclusion

Various industries use CNC machined parts. Their numerous applications can be attributed to the characteristics mentioned above. The process is also great for making large parts that would otherwise be impossible to manufacture using other techniques.
