An engine lathe is a versatile machine tool used for shaping and machining metal and other materials. It operates by rotating the workpiece against a stationary cutting tool, allowing for precise shaping, drilling, and threading. Engine lathes are commonly used in manufacturing and repair shops for producing cylindrical parts. These lathes come in various sizes and configurations, making them suitable for both small and large projects. Key features include adjustable speeds, various tool holders, and the ability to perform multiple operations, such as turning and facing. This flexibility makes engine lathes essential in many industrial applications.
