CNC milling is a highly accurate machining process that uses multi-point cutting tools to create parts. This manufacturing process is compatible with almost any material and offers high standards regarding surface finish.
​
It's also an efficient technology, offering short lead times and serial production capabilities.
How CNC milling works
Milling represents one of the most used machining processes in subtractive manufacturing.
This process uses a rotary cutting tool with a geometrically determined edge. Milling can be subdivided into face milling and peripheral milling. Face milling uses a vertical cutting axis to process frontal areas and cavities. Peripheral milling, on the other hand, is used for deep slots and threads, given its horizontal cutting axis. 

CNC milling use cases
CNC milling is a flexible manufacturing process, from prototyping to series production. That's because the process is highly accurate with excellent surface finishes, resulting in high repeatably and short lead times. It's an especially advantageous technology for parts requiring many features, e.g., drilled holes.

Available Finishes
Anodizing
This electrochemical process increases the thickness and toughness of the natural oxide layer on the surface of metal parts. Anodizing provides a protective, corrosion-resistant, and decorative finish.
Black Oxidizing
Also known as blackening, this process creates a black oxide coating on the surface of metal parts. Black oxidizing provides a durable and corrosion-resistant finish.
Hardening
A heat treatment process that improves the strength and durability of metal parts by heating them to a specific temperature and then rapidly cooling them. Hardening increases the parts' wear resistance and fatigue strength, making them more durable.
Painted
Additional color is applied to the printed part, often by a professional spray painting system. The part is properly prepared through accurate cleaning and a clearcoat to get the desired output.
Sandblasting
Abrasive sand is applied to the component under high pressure. This provides functional benefits (achieving a certain surface roughness) and optical advantages (polishing the surface).
Tempering
The metal part is heated to a specific temperature and then slowly cooled to achieve the desired level of hardness and toughness. Tempering improves the strength and toughness of the metal parts, making them more resistant to impact and wear.
