CNC Milling Key Features
CNC milling parts are components produced using a CNC milling machine. These machines use rotary cutters to remove material from the workpiece, creating complex shapes, slots, holes, and other features with high precision. CNC milling is suitable for a wide range of materials, including metals (aluminum, steel, titanium), plastics (POM, ABS, nylon), and composites, making it highly versatile for various industries.
Types of CNC Milling Processes
- 2D Milling: Basic form of milling for flat surfaces, slots, and contours in two dimensions. Ideal for parts with simple geometry such as plates, brackets, and frames.
- 3D Milling: Involves cutting three-dimensional shapes and features into the workpiece. Used for complex parts with intricate curves, pockets, and cavities in aerospace, automotive, and medical industries.
- Multi-axis Milling: Uses machines with more than three axes for highly complex parts with difficult-to-reach areas or intricate shapes such as turbine blades, molds, and medical devices.
