3D CNC engravings are precise millings and engravings that are created using CNC machines. These machines can create complex designs in various materials such as aluminium, copper, brass, bronze, non-ferrous metals and plastics.

CNC engraving offers high precision and repeatability. They enable complex and detailed designs that would be difficult or impossible to achieve using traditional methods. CNC machines are also faster and more efficient, which reduces production costs.

3D CNC engraving is used in many areas, including

Industry: labelling of control cabinets and machines.
Art and jewellery: production of decorative elements and pieces of jewellery.
Advertising technology: Creation of signs and logos.
Medical technology: engraving of precise instrument parts

Various machines and technologies are used for CNC engraving, including

CNC milling machines: For complex 3D engravings and reliefs.
Laser engraving machines: For precise and non-contact engraving, particularly suitable for sensitive materials.
Scribe engraving: For particularly fine lines and contours, often with diamond-coated engraving styli

Each material has specific requirements:

Aluminium: Easy to mill, but requires sharp tools and suitable coolants to avoid material build-up.
Copper and brass: Softer than many other metals, so they tend to deform and require careful handling.
Bronze: Harder than copper and brass, good for detailed engraving.
Plastics: Can melt easily, so a controlled milling speed and temperature is important.

The choice of material has a significant influence on the engraving technique. Harder materials such as bronze require more robust tools and possibly special milling techniques. Softer materials such as plastic require slower milling speeds and careful management of heat generation to ensure a clean engraving.

Companies offer a variety of services, including:

Cutting and sawing: Preparation of raw material.
CNC machining: Milling and engraving to specific requirements.
Surface treatment: Polishing, grinding and coating to improve the final quality of the product.
Laser marking: High-precision labelling for various applications.

CAD/CAM software solutions such as Fusion 360 or similar programmes are often used for the design and programming of CNC engravings. These enable the creation of detailed designs and the direct programming of CNC machines.
