With the continuous development of industrial technology, mechanical gears, as the core components of transmission devices, play an important role in various fields. The quality and accuracy of gears directly affect the transmission efficiency and working stability of mechanical devices, so the processing technology requirements for gears are getting higher and higher.
In the past, the processing of mechanical gears mainly relied on traditional milling, hobbing, grinding and other methods, but with the wide application of CNC technology, digital gear processing has gradually become the development trend of the industry. CNC gear machining has the characteristics of high precision, high efficiency and high stability, which can realize the processing needs of complex tooth surfaces, and reduce the difficulty and error rate of manual operation.
In CNC gear machining, commonly used machining methods include hobbing, milling, grinding, and EDM. Hobbing is the most common machining method, and by meshing with the tool teeth, it is possible to obtain high-precision and high-quality gears. Milling is suitable for the machining of large gears and special gears, and can realize the design requirements of various tooth profiles and tooth top clearances. Grinding is a machining method for high-precision gears, which can improve the surface quality and accuracy of gears. EDM is mainly used for the processing of non-metallic gears, which can realize the manufacture of complex tooth shapes.
In addition to the progress of processing methods, the development of materials science has also promoted the improvement of mechanical gear processing technology. The application of new materials, such as high-strength alloy steel, titanium alloy, etc., has improved the wear resistance and strength of gears. At the same time, the application of new coating technologies, such as nitriding, carbonization, etc., can improve the surface hardness and wear resistance of gears.
In short, the advancement of mechanical gear processing technology has made gears more widely used in various industries. The advent of digital gear machining has improved machining efficiency and work stability, and continuously improved the performance of mechanical devices. With the development of materials science, more new materials and coating technologies will further promote the development of mechanical gear processing technology and provide better solutions for industrial manufacturing.
