Vertical mills are a type of milling machine that use a vertical spindle to hold and rotate the cutting tool. This design allows for precise machining of materials like metal and wood, making them ideal for tasks such as drilling, boring, and shaping. The workpiece is typically secured on a table that can move in multiple directions, providing flexibility in the machining process. These machines are commonly used in manufacturing and fabrication industries. Vertical mills can be operated manually or controlled by computer numerical control (CNC) systems, which enhance accuracy and efficiency. They are essential tools for producing parts and components in various applications, from automotive to aerospace.
