In the early 1950s, China’s gear machine tool manufacturing industry began to develop through the full introduction of the technology of the former Soviet Union. Since the late last century, China’s gear processing CNC machine tools have ushered in a period of great development. In recent years, with the development of industrial modernization and the cultivation of technical talents, independent innovation and scientific research investment, China’s CNC gear processing machine tools have developed rapidly. Domestic enterprises such as Qinchuan machine tool factory, Tianjin No. 1 machine tool factory, Nanjing No. 2 machine tool factory and Chongqing machine tool factory are rising rapidly and occupy a place in the market share of gear processing machine tools. These enterprises have great investment in new product research and development, and there are many new gear processing machine tools to adapt to the fierce market competition.
As shown in Figure 1, it is an eleven axis five linkage gear grinding machine produced by Qinchuan machine tool factory. Model: ykz7230 CNC worm wheel gear grinding machine. The machine tool can process gears with modulus of 1-6mm and outer diameter of 300mm. It has a high degree of automation. It can not only automatically clamp the workpiece, but also automatically adjust the pressure angle. The machine tool not only adopts multiple heads
Grinding wheel grinding greatly improves the machining efficiency of Chinese gears, and the same phase dressing technology is also adopted to improve the dressing accuracy of grinding wheel.
As shown in Figure 2, it is ykn3112 CNC hobbing machine of Nanjing No. 2 machine tool factory. The main motion is driven by spindle servo motor. The radial and axial feed shafts are driven by independent AC servo motors. The gear hobbing machine has the characteristics of high transmission precision and good transmission rigidity.
For example, the Chinese gear processing machine tool of Chongqing Machine Tool Factory: yd31100 CNC six axis four linkage CNC gear hobbing machine. The gear hobbing machine can not only process straight, helical teeth and worm gears, but also process splines, drum gears, etc. In addition to the above, domestic enterprises have developed many new Chinese gear processing machines with high automation.
