随着汽车整车对发动机的动力性、经济性、环保性及可靠性的要求越来越严格,活塞已发展成为集轻质高强度新材料、异型外圆复合型面、异型销孔等多项新技术于一体的高技术含量的产品,以保证活塞的耐热性、耐磨性、平稳的导向性和良好的密封功能,减少发动机的摩擦功损失,降低油耗、噪声和排放。目前,国内活塞制造行业通常是由通用机床和结合活塞工艺特点的专用设备组成机加工生产线,因此,专用设备就成为活塞切削加工的关键设备,其功能和精度将直接影响最终产品的关键特性的质量指标。 With the vehicle on the engine power, economy, environmental protection and reliability requirements more stringent, the piston has developed into a set of light and high strength of new materials, special-shaped cylindrical composite surface, shaped pin hole and more New technology in one of the high-tech products to ensure that the piston heat resistance, wear resistance, smooth orientation and good sealing function, reduce engine friction loss, reduce fuel consumption, noise and emissions. At present, the domestic piston manufacturing industry is usually composed of general-purpose machine tools and special equipment that combines the characteristics of piston technology to form a machining line. Therefore, the special equipment becomes the key equipment for piston cutting. Its function and precision will directly affect the key characteristics of the final product Quality Index.
