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.
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 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.

Annealing involves heating metal parts to a specific temperature and slowly cooling them. This process reduces hardness, increases ductility, and relieves internal stresses, making the material easier to work with.
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.
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.
A layer of zinc is electrically deposited onto metal parts. Electrogalvanization provides excellent corrosion resistance and a smooth finish and can serve as a base for further painting or coating.
This electroplating process deposits a layer of nickel onto the surface of metal parts. Nickel plating enhances corrosion resistance, adds wear protection, and provides an attractive finish.
