Milling is crucial for shaping complex geometries. It can create pockets, slots, and contoured surfaces on robot parts. For example, when machining the base of an industrial robot, milling precisely removes material to form mounting holes and leveling surfaces. Multi-axis milling machines enable intricate 3D designs, ensuring perfect fit and functionality.
