Screw-Cutting Lathe 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.).
