A milling machine is a versatile tool used in manufacturing and machining processes to remove material from a workpiece. It operates by rotating a cutting tool (known as a mill) against a stationary object, shaping it into the desired form. Milling machines can perform a variety of functions such as cutting, drilling, and contouring, making them essential in metalworking, woodworking, and even plastic fabrication. These machines come in different types, including vertical and horizontal mills, and can be manually operated or CNC (computer numerical control) driven for precision and automation. Ideal for creating complex parts, milling machines are crucial for producing components in industries like automotive, aerospace, and industrial machinery.
