Using computerized controls and rotating spindle head, CNC milling removes material from the workpiece to create a part that meets the required specifications. A variety of substrates can be machined in this process, including plastic, metal, wood, and glass.
Several different processes can be used in CNC machining, including mechanical, chemical, electrical, and thermal processes. CNC milling falls under the category of a mechanical process since cutting and drilling are powered mechanically without any manual operation.
The CNC milling process follows the same steps many other machining types do. It can mainly be divided into the following steps: 1. Designing a CAD model and export it to a CNC file format. 2. Converting the CAD model into a CNC program using CAM software. 3. Setting up the CNC milling machine by setting up the worktable and the workholding device, and attaching the milling tools and machine spindle. 4. Executing the milling operation. Depending on the type of part, we can use horizontal or vertical milling machines. When the milling process starts, the cutting tool will rotate at incredibly high speeds — up to thousands of revolutions per minute! It can create many different shapes, holes and any other impression the part requires.

As MachinedThis is the standard finish option. Burrs and sharp edges are removed after machining.
AnodizedParts are anodized (Type II or III coating) to the surface, ideal to improve corrosion and wear resistance of components. Parts can be anodized in different colors, clear, black, red and gold are the most common.
ElectropolishedElectropolishing is a process that removes a thin layer of material from the surface of a metal part. This process can improve the surface finish, remove burrs, and enhance the corrosion resistance of the part.
BrushedBrushed finish is a surface treatment that creates a uniform, linear pattern on the surface of the metal. This finish is often used for decorative purposes and can help hide surface imperfections.
Powder CoatPowder coating is a dry finishing process that creates a hard, durable finish. The powder is applied electrostatically and then cured under heat to form a protective layer.
Laser EngravingLaser engraving is a process that uses a laser beam to create permanent marks on the surface of a material. This process is precise and can create detailed designs.
Screen PrintingScreen printing is a printing technique that uses a mesh-based stencil to apply ink onto a substrate. This process can be used to create detailed designs and logos on parts.
