Screw Thread Accuracy Services

A�screw-cutting lathe�is a machine (specifically, a�lathe) capable of cutting very accurate�screw threads�via�single-point screw-cutting, which is the process of guiding the�linear�motion of the�tool bit�in a precisely known ratio to the�rotating�motion of the workpiece. This is accomplished by�gearing�the�leadscrew�(which drives the tool bit�s movement) to the�spindle�with a certain gear ratio for each thread pitch. Every�degree�of spindle rotation is matched by a certain distance of linear tool travel, depending on the desired thread pitch (English or metric, fine or coarse, etc.).
