精密锻造是少无切屑加工的一种先进工艺。用这种锻造方法加工齿轮不仅可以提高劳动生产率、降低生产成本和减轻劳动强度,而且可以节约大批钢材,并且提高了齿轮的内在质量,增长使用寿命。我厂在毛主席的无产阶级革命路线指引下,不断改进精密锻造工艺,目前已用这种方法生产SH130型 Precision forging is less without chip processing an advanced technology. Machining gears with this forging method not only increases labor productivity, reduces production costs and reduces labor intensity, but also saves a large amount of steel, increases the inherent quality of gears and increases the service life. I plant under the guidance of Chairman Mao’s proletarian revolutionary line, continuous improvement of precision forging process, this method has been used to produce SH130
