在冲模生产中,常常遇到图1所示的长圆形零件。过去加工这类零件,为了保证长圆形(刃口)的精度,需要经过多道精加工工序,还要钳工精修成形。现在采用夹具加工,可在内、外圆磨床上一道工序磨削成形,不仅大大地提高了效率,缩短了生产周期,而且提高了质量。 夹具是利用长圆形的运动 In the die production, often encounter the oval parts shown in Figure 1. In the past to process such parts, in order to ensure the accuracy of oblong (edge), you need to go through multiple finishing processes, but also fitter finishing. Now the use of fixture processing, cylindrical grinder in a process of grinding and forming, not only greatly improve the efficiency and shorten the production cycle, but also improve the quality. Fixture is the use of oblong movement
