A CNC lathe is a computer-controlled machine tool used for shaping materials like metal or plastic. It rotates the workpiece against a cutting tool, allowing for precise shaping and finishing. The term "CNC" stands for Computer Numerical Control, which means the machine operates based on programmed instructions, ensuring high accuracy and repeatability. CNC lathes are commonly used in manufacturing industries to create cylindrical parts, such as shafts, bolts, and fittings. They can perform various operations, including turning, drilling, and threading, making them versatile tools in modern production processes.
