What is CNC Machining and How Does it Work?
CNC machining is an automated manufacturing process that transforms a solid block or rod of material into a part using end mills. The end mills are controlled by software (G-code) which references a 3D CAD model to reduce the stock material into a desired geometry. Parts can be manufactured relatively quickly due to the level of automation.
There are many types of CNC machines, which include CNC milling and CNC turning. CNC machining is a suitable manufacturing process for one-off prototypes or custom components as well as mid-volume production quantities.
Advantages of CNC Machining
The subtractive process of CNC machining provides multiple benefits for both prototyping and production parts.
- Precision and repeatability
- Tight tolerances
- Production-grade materials
- Quick-turn parts within 1 day

CNC Machining FAQs
How much does CNC machining cost?
The expense associated with our CNC machining service is variable and directly influenced by the distinct attributes of your project, including its design and tolerance specifications. The machining duration for the chosen material is another key determinant of the cost. To illustrate, should you require a part where the combined machining and material expense is $2, with an additional setup charge of $200, the total cost for a singular part would amount to $202. Contrastingly, should you commission the production of 200 identical parts, the cost per unit would be just $3!Learn more about the CNC machining costs.
What's the difference between 3D printing and CNC machining?
Manufacturing Process: 3D printing is an additive process, building parts layer by layer from materials like plastic or metal. In contrast, CNC machining is subtractive, cutting away material from a solid block to shape the final product.
Material Efficiency: 3D printing minimizes waste by using only the material needed to form the part, whereas CNC machining can produce more waste due to its subtractive nature.
Speed and Cost: For small batches and complex geometries, 3D printing can be faster and more cost-effective. CNC machining is preferable for larger volumes and materials requiring high precision and strength.
Surface Finish and Tolerances: CNC machining typically achieves better surface finishes and tighter tolerances compared to 3D printing.
What are the applications of CNC machining?
CNC machining has a wide range of applications across industries.
In the automotive and aerospace sectors, it is used to fabricate precise engine components, structural parts, and other intricate elements.
The medical industry leverages CNC for manufacturing devices, implants, and surgical instruments.
CNC is also crucial in electronics, enabling the production of electronic housings, circuit boards, and connectors.
Machine tool makers rely on CNC to create complex molds, dies, and machine components. Additionally,
CNC is valuable for general custom part production, prototyping, woodworking, and more, allowing for consistent quality and high precision.
