As a transmission component that efficiently converts rotational motion into linear motion, the lead screw has become a cornerstone in precision drive applications across automation systems. Its advantages of simple structure, cost-effectiveness, precise positioning, and high load capacity make it indispensable. The following case studies demonstrate its practical applications in industrial automation:
Application area | Specific equipment | Function of lead screw |
Numerical control machine | Vertical/longitudinal feed systems for lathes and milling machines | The rotary motion is converted to linear motion to achieve accurate feed |
Numerical control machine | Z-axis lifting system of CNC milling machine | Provide high rigidity support to suppress the cutting reaction force |
Automated assembly line | Jigs for automotive parts assembly lines | Drive the fixture to accurately grasp and place parts |
Logistics automation sorting line | Crossbar sorter | Drive the car to move in a straight line |
Heavy machinery and engineering equipment | Port gantry crane | Used for fixture positioning |
Numerical Control (NC) Machine Tools: In the longitudinal and transverse feed systems of CNC equipment such as lathes and milling machines, lead screws enhance feed speed to over 15 meters per minute while maintaining 0.01mm repeat positioning accuracy, meeting precision machining requirements. Additionally, lead screws are commonly employed in the Z-axis lifting systems of CNC milling machines. Their high-stiffness design effectively suppresses cutting reaction forces, ensuring optimal surface finish quality.
Automated Assembly Line: lead screws can be used to control the lifting and movement of fixtures in automated assembly lines, enabling automated assembly and processing of workpieces. For example, in automotive component assembly lines, these screws drive fixtures to accurately pick up and place parts, significantly improving both assembly efficiency and precision.
Logistics Automation Sorting Line: In the cross-belt sorter, a high-speed lead screw drives the cart to achieve linear motion at 1.5m/s. Combined with dynamic weighing and scanning systems, it processes over 20,000 packages per hour, tripling the efficiency of traditional belt conveyors. A logistics equipment manufacturer adopted hollow high-speed lead screws, achieving stable continuous operation temperatures below 60℃°C and reducing the failure rate by 40%.
In summary, lead screws have demonstrated strong applicability across various automation scenarios through their simple structure, precise positioning, and stable load-bearing performance. As critical transmission components, they serve as the core mechanism for converting rotational motion into linear motion, providing fundamental support for the stable operation and precise control of automated equipment. This makes them a widely adopted and practical transmission solution in automation systems.
