Originally, most manufacturing lathes featured threaded spindles. The spindle connects the rotating axle to the workpiece – but how? They can reach top spindle speeds up to twice as fast as belt-drive models and are correspondingly better for high-volume production runs. In extreme cases, it could take almost as long to spin up the lathe as it would to machine the workpiece.ĭirect-drive spindles are standard for modern lathes. Those cycle times become important when processing a high volume of parts, particularly smaller parts with shorter operation times. Belt-driven spindles are typical of older lathes they take longer to spin up to their top RPMs and longer to slow down. Machining spindles come in a number of varieties, but all spindles will either be direct-drive or belt-driven. ![]() The tailstock often has its own spindle, which allows a workpiece to be mounted between centers – two points of contact for better support, but still rotating cleanly. Most lathes consist of an engine housing, a headstock, a spindle or motor spindle that connects to the engine, the length of the bed, and then the lathe tailstock. Lathes are commonly used both for woodturning and metalworking. Lathes come in all shapes and sizes, from industrial CNC machines to mini lathes. Lathe tools are typically stationary cutters, though in some instances the cutting tool itself can be mounted to the spindle, giving it the same action as a traditional drill. This allows for cuts to be made along unusual geometries – cutting threads on a shaft, for instance. Unlike milling machines, lathes rotate the workpiece rather than the cutter. Lathes, or turning machines, are one of the oldest machine tools. In other words, the spindle works as a bridge – it connects the rotating motion of the axle to the workpiece and through to the tailstock, giving the lathe its unique range of cutting operations. ![]() The rotating part of the spindle connects back through the headstock to the axle. ![]() Some will have a shaft extending out over the bed of the lathe, while others will simply be flush with the headstock. The spindle itself is typically a metal plate or disc. It’s the part of the lathe that rotates – without the rotating spindle, a lathe isn’t a lathe at all. What is the lathe spindle? The spindle connects to the lathe engine’s axle through the headstock. Not necessarily a fascinating topic, but there’s no single part more important to the function of a lathe than the spindle.
