Ground ball screws high precision low noise custom reciprocating screws
This precision-ground ball screw is crafted from precision cold-rolled blanks using a full-stroke CNC precision grinding process. Each screw undergoes multiple rounds of precision calibration, achieving a high-precision level of C1–C5 in surface roughness and geometric accuracy. Positioning and repeatability are accurate to the micron level, easily handling demanding requirements such as high-speed transmission, precision positioning, and heavy-duty operation.
The screw undergoes fine grinding, resulting in precise thread profiles and a high surface finish, significantly reducing frictional resistance and achieving a transmission efficiency exceeding 95%. This leads to smoother, vibration-free, and low-noise equipment operation. The overall structure is rigid and resistant to deformation, and the small backlash design ensures stable accuracy even after long-term use, fundamentally reducing transmission backlash errors.
It can be widely used in high-end equipment such as CNC machine tools, automated equipment, precision instruments, and industrial robots. With its stable accuracy, low wear, long lifespan, and strong adaptability, it effectively improves equipment processing accuracy and work efficiency, making it a high-quality core component of precision transmission systems.
