High-precision ball screws tend to lose accuracy over time. Green Valley Transmission Times provides a professional solution through full-chain control covering raw materials, heat treatment, precision machining, and final inspection, ensuring long-lasting screw accuracy. The screws adopt optimized heat treatment processes to enhance thread surface hardness and reduce accuracy loss caused by long-term friction and wear. Precision-ground screws suppress the effects of thermal deformation and, combined with the preload structure, continuously maintain low-backlash transmission. Every screw undergoes full-stroke accuracy calibration before shipment, making it ideal for high-frequency reciprocating operations in lithium battery and 3C precision equipment. Green Valley Transmission Times also provides supporting protection solutions and technical guidance to extend the high-precision service life of screws and reduce maintenance costs for precision equipment.
