銑床, or "milling machine," is a versatile tool used in manufacturing to shape and cut materials, primarily metals. It operates by rotating a cutting tool against the workpiece, allowing for precise removal of material. This process is essential in creating complex shapes and features in various components. Milling machines come in different types, including vertical and horizontal configurations, each suited for specific tasks. They are commonly used in industries such as automotive and aerospace, where accuracy and efficiency are crucial. The ability to automate processes with CNC (Computer Numerical Control) technology further enhances their capabilities.
