It meets the requirements of high-speed, heavy-duty, low-noise, long-life and other requirements of modern mechanical transmission, and adopts high-efficiency and high-precision worm grinding wheel forming and grinding processing technology, which not only improves the manufacturing accuracy of gears, but also ensures precise contact and precise meshing of gears, and reduces operation Noise, and can also improve the smoothness and life of gears, has become one of the main development directions of gear grinding. Worm grinding wheels are suitable for precision CNC machine tools, matched with imported gear grinding machines, with good dynamic balance, strong grinding performance and less dressing.
