screw-cutting lathe
Quick Summary
A screw-cutting lathe is a specialized type of lathe designed for cutting threads on a workpiece. A lathe is a fundamental machine tool that removes material from a rotating workpiece using a cutting tool.12
In a screw-cutting lathe, a lead screw precisely controls the movement of the cutting tool. This mechanism ensures that the tool's motion is accurately synchronized with the workpiece's rotation, allowing for the creation of precise threads. This is a key distinction from other types of lathes, such as speed lathes or engine lathes, where tool manipulation or simpler power drives are used.2
