Precision grinding of ball screws is commonly used in CNC machining
Designed specifically for high-end equipment such as CNC machining centers, five-axis machine tools, and CNC lathes, this machine utilizes imported German bearing steel and a triple precision grinding process. Its precision grades cover C1-C5, with positioning accuracy up to ±0.003mm/300mm and repeatability ±0.001mm, perfectly meeting the micron-level machining requirements of precision molds and aerospace parts.
The innovative double-nut preload design increases dynamic rigidity by 40%, enabling it to withstand high-torque cutting loads. The optimized ball bearing circulation system, with a DN value up to 150,000, achieves high-speed, stable operation with noise levels below 55dB. Through cryogenic treatment and surface nitriding, its hardness reaches HRC60-62, increasing wear resistance by 50% and extending service life by more than three times.
With 20 inspection processes throughout the entire process, quality is traceable. It supports customized shaft end machining, special leads, and dust and corrosion protection solutions, making it a core transmission component for high-precision, high-efficiency machining on high-end CNC machine tools.
