What is the primary function of a milling machine?

The primary function of a milling machine is to remove material using rotary cutters for surface creation. Milling machines are designed to shape and fabricate components by removing material from a workpiece, typically metal, using a rotating cutting tool. This process allows for precise control of the depth and angle of the cut, enabling the creation of complex shapes, deep grooves, and intricate profiles.

Milling machines can perform various operations, including face milling, where the surface of the workpiece is flattened, and end milling, where edgings or detailing are added. These abilities make them essential tools in the machining industry, known for their versatility and accuracy in producing components that meet tight tolerances.

The other functions listed, such as rotating workpieces at high speeds, performing welding on components, and bending materials, do not align with the fundamental purpose of a milling machine. Instead, these tasks are suited to other types of machinery or processes, such as lathes for rotating workpieces, welding machines for joining materials, and presses or rollers for bending operations.
