High-Precision Linear Motion for CNC Systems
CNC machines require highly accurate and wear-resistant lead screws to ensure precise positioning. We have been manufacturing precision transmission components since 2011 and have supplied drive screw systems for Sany Heavy Industry. Their machine tools and automated systems require stable, repeatable positioning under continuous operation.
This Heavy Duty Lead Screw is used in CNC lathes, machining centers, grinding machines, and precision automation equipment. It is designed for high-load transmission, accurate positioning, and long service life under repetitive motion conditions.
Materials include GCr15 bearing steel, 40Cr, and 42CrMo alloy steel, selected for wear resistance, strength, and dimensional stability.
Precision Performance Data for High-Accuracy Motion
Heat treatment hardness is maintained at HRC 58–62 to ensure high surface wear resistance and long operational life.
Lead accuracy reaches IT3–IT5 grade, supporting ultra-precise positioning in CNC applications.
Radial runout is controlled within ≤0.005 mm to ensure stable rotation and smooth motion.
Straightness is controlled within ≤0.01 mm per 100 mm, ensuring consistent linear travel accuracy.
Surface roughness is maintained at Ra ≤ 0.4–0.8 μm to reduce friction and improve efficiency.
Applicable speed is up to 3000 r/min, suitable for high-speed feed systems.
Operating temperature range is -20°C to 80°C, suitable for standard industrial environments.
Precision Transmission Solution for Machine Tools
We do not only supply mechanical components-we deliver high-precision motion control solutions.
This Heavy Duty Lead Screw is widely used in CNC lathes, machining centers, precision slides, automatic positioning systems, and CNC cutting equipment.
It is designed for applications requiring extremely accurate linear motion, stable load transmission, and long-term dimensional consistency.
With over a decade of manufacturing experience since 2011, we focus on producing lead screws that maintain precision under heavy-duty industrial use.
