CNC Milling –
Precisie en veelzijdigheid
in verspaningstechniek 

As a pioneer in the European manufacturing industry, VRT has been offering professional CNC milling and turning services for nearly 28 years. We distinguish ourselves by working with advanced 3-axis and 5-axis CNC milling machines that enable us to produce precision parts from high-quality plastics and metals.

What is CNC milling?  

CNC milling is a subtractive manufacturing process where material is precisely removed using computer-controlled rotating cutting tools. This technique is one of the most versatile machining methods for creating complex components from plastic or metal. CNC milling stands out for its ability to produce accurate products with excellent surface quality and tolerances.

How does CNC milling work? 

In the CNC milling process, cutting tools are controlled with high precision by a computer. The process works according to the following principle:
 

1. A digital 3D model or 2D drawing is converted to G-code through CAM software 
2. The base material (plastic or metal) is securely fixed in the milling machine 
3. Computer-controlled milling heads selectively remove material according to the programmed path 
4. Different tools are automatically exchanged for various operations 
5. The workpiece undergoes multiple processing steps, from rough to fine 
6. Any complex contours are achieved through 3D, 4D, or 5D movements
   
   With modern 5-axis milling machines, we can create complex shapes with undercuts that would be impossible with conventional 3-axis machines. This offers unprecedented design freedom for your project.

Benefits of CNC milling    

CNC milling offers an excellent balance between accuracy, flexibility, and material choice freedom. The technique is known for precision and quality. 

The main benefits include: 

• Exceptional accuracy – Tolerances down to 0.01 mm possible for critical components

• Wide range of materials – From various plastics (PC, Nylon, PP, POM, ABS) to metals (aluminium, steel)

• No mold costs – Direct from CAD model to end product without expensive tooling

Additionally, CNC milling offers excellent surface quality, possibilities for complex undercuts, and the freedom to quickly adapt designs without high costs. This combination makes the technique ideal for prototypes, small series, and complex components. 

What are the applications of CNC milling?       

CNC milling is particularly versatile and can be applied for various purposes: 

• Prototyping – Rapid realization of functional prototypes in the final material

• Small to medium batches – Economically viable production without mold investments

• Complex components – Realization of parts with complex geometries

• Precision parts – Products with high dimensional accuracy for critical applications

• Custom components – Bespoke parts for specific projects

CNC milling versus other techniques       

CNC milling versus 3D printing   

Where 3D printing excels in creating complex internal structures and lightweight components, CNC milling offers superior surface quality and accuracy. CNC milled parts have consistent material properties without the anisotropy that often occurs in printed objects. Furthermore, a wider range of high-quality materials is available for CNC milling. For precision components where dimensional stability and surface quality are crucial, CNC milling is often the better choice.

CNC milling versus injection moulding   

CNC milling distinguishes itself from injection moulding by the absence of mold costs and the flexibility to implement rapid design changes. While injection moulding becomes economically advantageous for larger series, CNC milling remains the preferred technique for small series, prototypes, and complex geometries. CNC milling is also immediately available with typical lead times of 2 weeks, while injection moulding has a longer lead time for mold development. For small series or components with frequent design changes, CNC milling offers clear advantages.
