Core Viewpoint - The production and processing of lead screws is a complex multi-step process that includes various machining techniques and benefits from cold heading technology [1] Group 1: Production Process - The lead screw production process involves several stages: raw material forming, rough machining (turning, milling, drilling), thread rolling for spiral grooves, heat treatment, grinding, and assembly into lead screw components [1] - Cold heading technology is currently utilized only for the initial forming of raw parts, providing a certain shape for subsequent processing [1] Group 2: Advantages of Cold Heading - Cold heading offers several advantages, including minimal cutting, the ability to replace some turning/milling processes, material savings, and production efficiency that is several times higher than traditional cutting methods [1]
