Precision ground ball screw C3/C5 grade high-precision transmission screw
This ground ball screw employs precision cold rolling and full-stroke CNC grinding processes. Its surface roughness and geometric accuracy undergo rigorous testing, achieving ultra-high precision of C1–C5 levels. Positioning accuracy and repeatability are both at the micron level, meeting the demands of high-speed, high-precision, and heavy-duty transmission applications.
The screw undergoes precision grinding, resulting in high tooth profile accuracy and a smooth surface, effectively reducing friction loss and achieving a transmission efficiency exceeding 95%. This results in smoother, vibration-free, and noiseless operation. The integrated ground structure provides high rigidity and minimal backlash, preventing deformation over long-term use and effectively eliminating transmission backlash.
The product is compatible with high-end equipment such as CNC machine tools, automated equipment, precision instruments, and robots. It boasts advantages such as high precision, high rigidity, high stability, and long lifespan, significantly improving equipment positioning accuracy and operating efficiency, making it a preferred component for precision transmission systems.
